Description

Field of the Invention

[0001] This invention relates to novel aryl containing compounds that possess a phosphonate group that are inhibitors of Fructose-1,6-bisphosphatase. The invention also relates to the preparation and use of these compounds in the treatment of diabetes, and other diseases where the inhibition of gluconeogenesis, control of blood glucose levels, reduction in glycogen storage, or reduction in insulin levels is beneficial.

Background and Introduction to the Invention

[0002] The following description of the background of the invention is provided to aid in understanding the invention, but is not admitted to be, or to describe, prior art to the invention.

[0003] Diabetes mellitus (or diabetes) is one of the most prevalent diseases in the world today. Diabetic patients have been divided into two classes, namely type I or insulin-dependent diabetes mellitus and type II or non-insulin dependent diabetes mellitus (NIDDM). NIDDM accounts for approximately 90% of all diabetics and is estimated to affect 12-14 million adults in the U. S. alone (6.6% of the population). NIDDM is characterized by both fasting hyperglycemia and exaggerated postprandial increases in plasma glucose levels. NIDDM is associated with a variety of long-term complications, including microvascular diseases such as retinopathy, nephropathy and neuropathy, and macrovascular diseases such as coronary heart disease. Numerous studies in animal models demonstrate a causal relationship between long term hyperglycemia and complications. Results from the Diabetes Control and Complications Trial (DCCT) and the Stockholm Prospective Study demonstrate this relationship for the first time in man by showing that insulin-dependent diabetics with tighter glycemic control are at substantially lower risk for the development and progression of these complications. Tighter control is also expected to benefit NIDDM patients.

[0004] Current therapies used to treat NIDDM patients entail both controlling lifestyle risk factors and pharmaceutical intervention. First-line therapy for NIDDM is typically a tightly-controlled regimen of diet and exercise since an overwhelming number of NIDDM patients are overweight or obese (67%) and since weight loss can improve insulin secretion, insulin sensitivity and lead to normoglycemia. Normalization of blood glucose occurs in less than 30% of these patients due to poor compliance and poor response. Patients with hyperglycemia not controlled by diet alone are subsequently treated with oral hypoglycemics or insulin. Until recently, the sulfonylureas were the only class of oral hypoglycemic agents available for NIDDM. Treatment with sulfonylureas leads to effective blood glucose lowering in only 70% of patients and only 40% after 10 years of therapy. Patients that fail to respond to diet and sulfonylureas are subsequently treated with daily insulin injections to gain adequate glycemic control.

[0005] Although the sulfonylureas represent a major therapy for NIDDM patients, four factors limit their overall success. First, as mentioned above, a large segment of the MDDM population do not respond adequately to sulfonylurea therapy (i.e. primary failures) or become resistant (i.e. secondary failures). This is particularly true in NIDDM patients with advanced NIDDM since these patients have severely impaired insulin secretion. Second, sulfonylurea therapy is associated with an increased risk of severe hypoglycemic episodes. Third, chronic hyperinsulinemia has been associated with increased cardiovascular disease although this relationship is considered controversial and unproven. Last, sulfonylureas are associated with weight gain, which leads to worsening of peripheral insulin sensitivity and thereby can accelerate the progression of the disease.

[0006] Results from the U.K. Diabetes Prospective Study also showed that patients undergoing maximal therapy of a sulfonylurea, metformin, or a combination of the two, were unable to maintain normal fasting glycemia over the six year period of the study. U.K. Prospective Diabetes Study 16. Diabetes, 44:1249-158. (1995). These results further illustrate the great need for alternative therapies.

[0007] Gluconeogenesis from pyruvate and other 3-carbon precursors is a highly regulated biosynthetic pathway requiring eleven enzymes. Seven enzymes catalyze reversible reactions and are common to both gluconeogenesis and glycolysis. Four enzymes catalyze reactions unique to gluconeogenesis, namely pyruvate carboxylase, phosphoenolpyruvate carboxykinase, fructose-1,6-bisphosphatase and glucose-6-phosphatase. Overall flux through the pathway is controlled by the specific activities of these enzymes, the enzymes that catalyzed the corresponding steps in the glycolytic direction, and by substrate availability. Dietary factors (glucose, fat) and hormones (insulin, glucagon, glucocorticoids, epinephrine) coordinatively regulate enzyme activities in the gluconeogenesis and glycolysis pathways through gene expression and post-translational mechanisms.

[0008] Of the four enzymes specific to gluconeogenesis, fructose-1,6-bisphosphatase (hereinafter "FBPase") is the most suitable target for a gluconeogenesis inhibitor based on efficacy and safety considerations. Studies indicate that nature uses the FBPase/PFK cycle as a major control point (metabolic switch) responsible for determining whether metabolic flux proceeds in the direction of glycolysis or gluconeogenesis. Claus, et al., Mechanisms of Insulin Action, Belfrage, P. editor, pp.305-321, Elsevier Science 1992; Regen, et al. J. Theor. Biol., 111:635-658 (1984); Pilkis, et al. Annu. Rev. Biochem, 57:755-783 (1988). FBPase is inhibited by fructose-2,6-bisphosphate in the cell. Fructose-2,6-bisphosphate binds to the substrate site of the enzyme. AMP binds to an allosteric site on the enzyme.

[0009] Synthetic inhibitors of FBPase have also been reported. McNiel reported that fructose-2,6-bisphosphate analogs inhibit FBPase by binding to the substrate site. J. Am. Chem. Soc., 106:7851-7853 (1984); U.S. Patent No. 4,968,790 (1984). These compounds, however, were relatively weak and did not inhibit glucose production in hepatocytes presumably due to poor cell penetration.

[0010] Gruber reported that some nucleosides can lower blood glucose in the whole animal through inhibition of FBPase. These compounds exert their activity by first undergoing phosphorylation to the corresponding monophosphate. EP 0 427 799 B1.

[0011] Gruber et al. U.S. Patent No. 5,658,889 described the use of inhibitors of the AMP site of FBPase to treat diabetes. WO 98/39344, WO 98/39343, WO 98/39342 and WO 00/14095 describe specific inhibitors of FBPase to treat diabetes.

[0084] The term "prodrug ester" as employed herein refers to esters of phosphonic acids or phosphoramic acids and includes, but is not limited to, the following groups and combinations of these groups:

[1] Acyloxyalkyl esters which are well described in the literature (Farquhar et al., J. Pharm. Sci. 72, 324-325 (1983)) and are represented by formula A

wherein R, R', and R" are independently H, alkyl, aryl, alkylaryl, and alicyclic; (see WO 90/08155; WO 90/10636).

[2] Other acyloxyalkyl esters are possible in which an alicyclic ring is formed such as shown in formula B. These esters have been shown to generate phosphorus-containing nucleotides inside cells through a postulated sequence of reactions beginning with deesterification and followed by a series of elimination reactions (e.g. Freed et al., Biochem. Pharm. 38: 3193-3198 (1989)).

wherein R is -H, alkyl, aryl, alkylaryl, alkoxy, aryloxy, alkylthio, arylthio, alkylamino, arylamino, cycloalkyl, or alicyclic.

[3] Another class of these double esters known as alkyloxycarbonyloxymethyl esters, as shown in formula A, where R is alkoxy, aryloxy, alkylthio, arylthio, alkylamino, and arylamino; R', and R" are independently H, alkyl, aryl, alkylaryl, and alicyclic, have been studied in the area of β-lactam antibiotics (Tatsuo Nishimura et al. J. Antibiotics, 1987, 40(1), 81-90; for a review see Ferres, H., Drugs of Today, 1983, 19, 499.). More recently Cathy, M. S., et al. (Abstract from AAPS Western Regional Meeting, April, 1997) showed that these alkyloxycarbonyloxymethyl ester prodrugs on (9-[(R)-2-phosphonomethoxy)propyl]adenine (PMPA) are bioavailable up to 30% in dogs.

[4] Aryl esters have also been used as phosphonate prodrugs (e.g. Erion, DeLambert et al., J. Med. Chem. 37: 498, 1994; Serafinowska et al., J. Med. Chem. 38: 1372, 1995). Phenyl as well as mono and poly-substituted phenyl proesters have generated the parent phosphonic acid in studies conducted in animals and in man (Formula C). Another approach has been described where Y is a carboxylic ester ortho to the phosphate. Khamnei and Torrence, J. Med. Chem.; 39:4109-4115 (1996).

wherein: Y is H, alkyl, aryl, alkylaryl, alkoxy, acyloxy, halogen, amino, alkoxycarbonyl, hydroxy, cyano, and alicyclic.

[5] Benzyl esters have also been reported to generate the parent phosphonic acid. In some cases, using substituents at the para-position can accelerate the hydrolysis. Benzyl analogs with 4-acyloxy or 4-alkyloxy group [Formula D, X = H, OR or O(CO)R or O(CO)OR] can generate the 4-hydroxy compound more readily through the action of enzymes, e.g. oxidases, esterases, etc. Examples of this class of prodrugs are described in Mitchell et al., J. Chem. Soc. Perkin Trans. I 2345 (1992); Brook, et al. WO 91/19721.

wherein X and Y are independently H, alkyl, aryl, alkylaryl, alkoxy, acyloxy, hydroxy, cyano, nitro, perhaloalkyl, halo, or alkyloxycarbonyl; and R' and R" are independently H, alkyl, aryl, alkylaryl, halogen, and alicyclic.

[6] Thio-containing phosphonate proesters have been described that are useful in the delivery of FBPase inhibitors to hepatocytes. These proesters contain a protected thioethyl moiety as shown in formula E. One or more of the oxygens of the phosphonate can be esterified. Since the mechanism that results in de-esterification requires the generation of a free thiolate, a variety ofthiol protecting groups are possible. For example, the disulfide is reduced by a reductase-mediated process (Puech et al., Antiviral Res., 22: 155-174 (1993)). Thioesters will also generate free thiolates after esterase-mediated hydrolysis. Benzaria, et al., J. Med. Chem., 39:4958 (1996). Cyclic analogs are also possible and were shown to liberate phosphonate in isolated rat hepatocytes. The cyclic disulfide shown below has not been previously described and is novel.

In some cases it is at least 100%. Measurement of oral bioavailability usually refers to measurements of the prodrug, drug, or drug metabolite in blood, tissues, or urine following oral administration compared to measurements following systemic administration.

[0099] The term "parent drug" refers to any compound which delivers the same biologically active compound. The parent drug form is P(O)(OH)₂-L-R⁵ and standard prodrugs, such as esters.

[0120] In one aspect of the invention are compounds wherein both Y groups are -0- and R¹ is -H. In another aspect are compounds wherein both Y groups are -O-, and R¹ is -CH₂OC(O)OEt. In yet another aspect are compounds are such wherein both Y groups are -O-, and R¹ and R¹ together are

and V is phenyl substituted with 1-3 halogens. Within such a group are compounds wherein V is selected from the group consisting of 3,5-dichlorophenyl, 3-bromo-4-fluorophenyl, 3-chlorophenyl, 2-bromophenyl, and 3-bromophenyl.

[0121] In one aspect of the invention are such compounds wherein n is 1, and the carbon attached to R¹² and R¹³ has S stereochemistry.

[0122] In another aspect of the invention are compounds wherein R¹⁵ is not H.

[0123] In yet another aspect of the invention are compounds of formula I wherein -NR¹⁵R¹⁶ is a cyclic amine. Within such a group are compounds wherein -NR¹⁵R¹⁶ is selected from the group consisting of morpholinyl and pyrrolidinyl. In another aspect of the invention, R¹⁶ groups include -(CR¹²R¹³)_n-C(O)-R¹⁴. In yet another aspect are compounds with the formula

[0124] Within such a group are compounds wherein n is 1. In one aspect of the invention compounds are envisioned wherein when R¹² and R¹³ are not the same, then R¹⁴-C(O)-CR¹²R¹³-NH₂ is an ester or thioester of a naturally occurring amino acid; and R¹⁴ is selected from the group consisting of -OR¹⁷ and -SR¹⁷.

[0125] In one aspect of the invention are compounds wherein one Y is -O- and its corresponding R¹ is optionally substituted phenyl, while the other Y is -NH-, and its corresponding R¹ is -C(R²)₂-COOR³. When R¹ is -CHR³COOR³, then the corresponding -NR⁶-*CHR³COOR³, generally has L stereochemistry.

[0126] In general, substituents V, Z, W, W', V², Z², W², W", Z', D', D", and W³ of formula I are chosen such that they exhibit one or more of the following properties:

(1) enhance the oxidation reaction since this reaction is likely to be the rate determining step and therefore must compete with drug elimination processes.

(2) enhance stability in aqueous solution and in the presence of other non-p450 enzymes;

(3) enhance cell penetration, e.g. substituents are not charged or of high molecular weight since both properties can limit oral bioavailability as well as cell penetration;

(4) promote the β-elimination reaction following the initial oxidation by producing ring-opened products that have one or more of the following properties:

a) fail to recyclize;

b) undergo limited covalent hydration;

c) promote β-elimination by assisting in the proton abstraction;

d) impede addition reactions that form stable adducts, e.g. thiols to the initial hydroxylated product or nucleophilic addition to the carbonyl generated after ring opening; and

e) limit metabolism of reaction intermediates (e.g. ring-opened ketone);

(5) lead to a non-toxic and non-mutagenic by-product with one or more of the following characteristics. Both properties can be minimized by using substituents that limit Michael additions, reactions, e.g.

a) electron donating Z groups that decrease double bond polarization;

b) W groups that sterically block nucleophilic addition to β-carbon;

c) Z groups that eliminate the double bond after the elimination reaction either through retautomerization (enol->keto) or hydrolysis (e.g. enamine);

d) V groups that contain groups that add to the α,β-unsaturated ketone to form a ring;

e) Z groups that form a stable ring via Michael addition to double bond; and

f) groups that enhance detoxification of the by-product by one or more of the following characteristics:

(i) confine to liver, and

(ii) make susceptible to detoxification reactions (e.g. ketone reduction); and

(6) capable of generating a pharmacologically active product.

[0127] In yet another aspect of the invention, when together V and Z are connected via an additional 3-5 atoms to form a cyclic group, optionally containing 1 heteroatom, said cyclic group is fused to an aryl group at the beta and gamma positions to the Y attached to phosphorus. In such compounds it is envisioned that said aryl group may be an optionally substituted monocyclic aryl group and the connection between Z and the gamma position of the aryl group is selected from the group consisting of O, CH₂, CH₂CH₂, OCH₂ or CH₂O.

[0128] In another aspect, together V and W are connected via an additional 3 carbon atoms to form an optionally substituted cyclic group containing 6 carbon atoms and monosubstituted with one substituent selected from the group consisting of hydroxy, acyloxy, alkoxycarbonyloxy, alkylthiocarbonyloxy, and aryloxycarbonyloxy attached to one of said additional carbon atoms that is three atoms from a Y attached to the phosphorus. In such compounds, it is envisioned that together V and W may form a cyclic group selected from the group consisting of -CH₂-CH(OH)-CH₂-, CH₂CH(OCOR³)-CH₂-, and -CH₂CH(OCO₂R³)-CH₂-.

[0129] In another aspect, V group is 1-alkene. Oxidation by p450 enzymes is known to occur at benzylic and allylic carbons.

[0130] In yet another aspect of the invention, prodrugs of formula VI are:

wherein

V is selected from the group consisting of aryl, substituted aryl, heteroaryl, and substituted heteroaryl, 1-alkenyl, and 1-alkynyl. In another aspect V groups of formula-VI are aryl, substituted, heteroaryl, and substituted heteroaryl. Within such a group aryl and substituted aryl groups include phenyl and substituted phenyl. Within such a group heteroaryl groups include monocyclic substituted and unsubstituted heteroaryl groups. Such heteroaryls include 4-pyridyl and 3-bromopyridyl. In another aspect of the invention, Y is -O-.

[0131] In one aspect, the compounds of formula I have a group Z which is -H, alkyl, alicyclic, hydroxy, alkoxy,

or -NHCOR. Within such a group are compounds in which Z decreases the propensity of the byproduct, vinyl aryl ketone to undergo Michael additions. Such Z groups are groups that donate electrons to the vinyl group which is a known strategy for decreasing the propensity of α,β-unsaturated carbonyl compounds to undergo a Michael addition. For example, a methyl group in a similar position on acrylamide results in no mutagenic activity whereas the unsubstituted vinyl analog is highly mutagenic. Other groups could serve a similar function, e.g. Z=OR, NHAc, etc. Other groups may also prevent the Michael addition especially groups that result in removal of the double bond altogether such as Z = OH, -OC(O)R, -OCO₂R, and NH₂, which will rapidly undergo retautomerization after the elimination reaction. Certain W and W' groups are also advantageous in this role since the group(s) impede the addition reaction to the β-carbon or destabilize the product. Another suitable Z group is one that contains a nucleophilic group capable of adding to the α,β-unsaturated double bond after the elimination reaction i.e. (CH₂)_p-SH or (CH₂)_p-OH where p is 2 or 3. Yet another suitable group is a group attached to V which is capable of adding to the α,β-unsaturated double bond after the elimination reaction:

[0132] In another aspect of the invention are prodrugs of formula VII:

wherein

Z² is selected from the group consisting of -CHR²OH, -CHR²OCOR³, -CHR²OC(S)R³, -CHR²OCO₂R³, -CHR²OC(O)SR³, and -CHR²OC(S)OR³. Within such a group, Z² may be selected from the group of -CHR²OH, -CHR²OC(O)R³, and -CHR²OCO₂R³. In one aspect of the invention, Y is -O-.

[0133] In another aspect of the invention are prodrugs of formula VIII:

wherein

Z' is selected from the group consisting of -OH, -OC(O)R³, -OCO₂R³, and -OC(O)SR³;

D' is -H; and

D" is selected from the group consisting of -H, alkyl, -OR², -OH, and -OC(O)R³. In one aspect of the invention Y is -O-.

[0134] In one embodiment, W' and Z are -H, W and V are both the same aryl, substituted aryl, heteroaryl, or substituted heteroaryl such that the phosphonate prodrug moiety:

has a plane of symmetry. In one aspect of the invention Y is -O-.

[0135] In one aspect, oral bioavailability is at least 5%. In another aspect, oral bioavailability is at least 10%.

[0136] p450 oxidation can be sensitive to stereochemistry which might either be at phosphorus or at the carbon bearing the aromatic group. The prodrugs of the present invention have two isomeric forms around the phosphorus. One aspect of the invention is the stereochemistry that enables both oxidation and the elimination reaction. Within such a group are the compounds where V is trans to the phosphorous-oxygen double bond.

[0137] It is envisioned that compounds of formula VIII may utilize a Z' group that is capable of undergoing an oxidative reaction that yields an unstable intermediate which via elimination reactions breaks down to the corresponding P(O)(O^-)₂-L-R⁵, P(O)(NHR⁶)₂-R⁵,

Synthesis of Compounds of Formula I

[0143] Synthesis of compounds encompassed by the present invention typically includes some or all of the following general steps as represented in the scheme below: (a) coupling of a phosphonate fragment (1a or 1b) with an aryl or heteroaryl ring fragment (2a or 2b, respectively); (b) modification of the coupled molecule if necessary, (c) deprotection of a phosphonate diester (3) to give a phosphonic acid (4) and (d) preparation of a phosphonate prodrug.

(a) Coupling of a phosphonate fragment (1) with an aryl moiety (2).

[0144] When feasible, compounds disclosed in the present invention are advantageously prepared via a convergent synthetic route entailing the coupling of a phosphonate component with an aryl or heteroaryl ring fragment.

[0145] Transition metal-catalyzed coupling reactions such as Stille and Suzuki reactions are particularly suited for the synthesis of compounds of formula I (Farina et al, Organic Reactions, Vol. 50; Wiley, New York, 1997; Suzuki in Metal Catalyzed Cross-Coupling Reactions; Wiley VCH, 1998, pp 49-97). Coupling reactions between a compound 1 (wherein B is preferably a Bu₃Sn) and a compound 2 (wherein A is e.g. an iodo, bromo or trifluoromethylsulfonate) under palladium-catalyzed reaction conditions to yield compounds of formula 3 wherein L is e.g. a 2,5-furanyl. The same type of coupling between a compound 1 (wherein B is preferably an iodo group) and a compound 2 (wherein A = B(OH)₂ or a Bu₃Sn) can also be used to yield compounds of formula 3 wherein L is e.g. a 2,5-furanyl.

[0146] The reactants 2 that are substituted aryl and heteroaryl compounds are either commercially available or readily synthesized using known methodology. The coupling agents 1 are also prepared using well-known chemistry. For example when L is a 2,5-furanyl, the coupling agent 1 is prepared starting from furan using organolithium techniques. Lithiation of furan using known methods (e.g. n-BuLi/TMEDA, Gschwend Org. React. 1979, 26: 1) followed by addition ofphosphorylating agents (e.g. ClPO₃R₂) give 2-dialkylphosphono-furans (e.g. 2-diethylphosphonofuran). Synthesis of 2,5-disubstituted furan building blocks can be completed by lithiation of a 2-dialkylphosphonofuran (e.g. 2-diethylphosphonofuran) with a suitable base (e.g. LDA) followed by trapping of the generated anion with an electrophile (e.g. with tributyltinchloride, triisopropyl borate or iodine) to produce a 5-functionalized-2-dialkylphosphonofuran (e.g. 5-tributylstannyl-2-diethylphosphonofuran, 2-diethylphosphonofuran-5-boronic acid or 5-iodo-2-diethylphosphonofuran, respectively).

[0147] It is envisioned that the above described methods for the synthesis of furan derivatives can be either directly or with some modifications applied to syntheses of various other useful intermediates such as aryl phosphonate esters (e.g. thienyl phosphonate esters, phenyl phosphonate esters or pyridyl phosphonate esters).

[0148] Known amide bond formation reactions can be used to couple a phosphonate diester building block 1 with an aryl or heteroaryl ring intermediate 2 leading to compounds of formula I wherein L is a alkyleneaminocarbonyl or an alkylenecarbonylamino group. For example, coupling of an aryl carboxylic acid preferably with diethyl aminomethylphosphonate can result in a compound of formula I wherein the ring fragment incorporated from intermediate 2 is an aryl and the L fragment is -CH₂NHC(O)-. Similarly, substitution of diethyl alkylaminoalkylphosphonates in this method may produce compounds with an L fragment represented by -R'C(R")N(R)C(O)-. Alternatively, for example, coupling of an aryl amine preferably with diethylphosphonoacetic acid can result in a compound of formula I wherein the ring fragment incorporated from intermediate 2 is an aryl and the L fragment is -CH₂C(O)NH-. Compounds with an L fragment of -R'C(R")C(O)NR- may be prepared by extension of this method.

[0149] Known ether bond formation reactions can be used to produce compounds of formula I where L is an alkylene-O group. For example, the sodium salt of a phenol may be alkylated with diethyl (iodomethyl)phosphonate or preferably diethylphosphonomethyl triflate to produce compounds of formula I where L is -alkylene-O.

[0150] For compounds of formula I wherein L is an alkyl group, the phosphonate group can be introduced using other common phosphonate formation methods such as Michaelis-Arbuzov reaction (Bhattacharya et al., Chem. Rev., 1981, 81: 415), Michaelis-Becker reaction (Blackburn et al., J. Organomet. Chem., 1988, 348: 55), and addition reactions of phosphorus to electrophiles (such as aldehydes, ketones, acyl halides, imines and other carbonyl derivatives).

[0151] When feasible and sometimes advantageous, compounds of formula 3 can also be prepared from an aryl compound (2b) via the introduction of a phosphonate moiety such as a dialkylphosphono group (e.g. a diethylphosphono group). For example, compounds of formula I wherein L is a 1,2-ethynyl can be prepared via the lithiation of a terminal arylalkyne followed by reacting the anion with a phosphorylating agent (e.g. ClPO₃R₂) to give an arylalkynylphosphonate. The required arylalkynes are readily made using conventional chemistry. For example, arylalkynes can be derived from reactions of aryl halides (e.g. iodides, bromides) or triflates and trimethylsilylacetylene using Sonogashira reactions (Sonogashira in Comprehensive Organic Synthesis, Pergamon Press: New York, 1991, vol. 3, pp 521-549) followed by deprotection of the trimethylsilyl group to give terminal arylalkynes.

(b) Modification of the coupled molecule.

[0152] The coupled molecule 3 can be modified in a variety of ways. Aryl halides (J²-J⁶ each optionally e.g. Br, I or O-triflate) are useful intermediates and are often readily converted to other substituents such as aryls, olefins, alkyls, alkynyls, arylamines and aryloxy groups via transition metal assisted coupling reactions such as Stille, Suzuki, Heck, Sonogashira and other reactions (Farina et al, Organic Reactions, Vol. 50; Wiley, New York, 1997; Mitchell, Synthesis, 1992, 808; Suzuki in Metal Catalyzed Cross-Coupling Reactions; Wiley VCH, 1998, pp 49-97; Heck Palladium Reagents in Organic Synthesis; Academic Press: San Diego, 1985; Sonogashira in Comprehensive Organic Synthesis, Pergamon Press: New York, 1991, vol. 3, pp 521-549, Buchwald J. Am. Chem. Soc. 1999, 121, 4369-4378; Hartwig, J. Am. Chem. Soc. 1999, 121, 3224-3225; Buchwald Acc. Chem. Res. 1998, 31, 805).

[0153] Compounds of formula I wherein J²-J⁶ are each optionally is a carboxamido group can be made from their corresponding alkyl carboxylate esters via aminolysis using various amines, or by reaction of carboxylic acids with amines under standard amide bond formation reaction conditions (e.g.: DIC/HOBt mediated amide bond formation).

[0154] Compounds of formula I wherein J²-J⁶ are each optionally a carboxylate ester group can be made from the corresponding carboxylic acids by standard esterification reactions (e.g. DIEA/DMF/alkyl iodide or EDCI, DMAP and an alcohol), or from the corresponding aryl halides/triflates via transition metal-catalyzed carbonylation reactions.

[0155] Compounds of formula I wherein J²-J⁶ are each optionally is an alkylaminoalkyl or arylaminoalkyl group can be prepared from their corresponding aldehydes by standard reductive amination reactions (e.g. aryl or alkyl amine, TMOF, AcOH, DMSO, NaBH₄).

(c) Deprotection of a phosphonate or phosphoramidate ester

[0156] Compounds of formula 4 may be prepared from phosphonate esters using known phosphate and phosphonate ester cleavage conditions. Silyl halides are generally used to cleave various phosphonate esters. When required, acid scavengers (e.g. 1,1,1,3,3,3-hexamethyldisilazane, 2,6-lutidine etc.) can be used for the synthesis of acid labile compounds. Such silyl halides include preferably bromotrimethylsilane (McKenna, et al, Tetrahedron Lett., 1977, 155), chlorotrimethylsilane (Rabinowitz, J. Org. Chem., 1963, 28: 2975) and iodotrimethylsilane (Blackburn, et al, J. Chem. Soc., Chem. Commun., 1978, 870). Alternately, phosphonate esters can be cleaved under strong acidic conditions (e.g. HBr, HCl: Moffatt, et al, U.S. Patent 3,524,846, 1970). Aryl and benzyl phosphonate esters can be cleaved under hydrogenolysis conditions (Lejczak, et al, Synthesis, 1982, 412; Elliott, et al, J. Med. Chem., 1985, 28: 1208; Baddiley, et al, Nature, 1953, 171, 76).

(d) Preparation of a phosphonate or phosphoramidate prodrug

[0157] The prodrug substitution can be introduced at different stages of the synthesis. Most often the prodrug is made from the phosphonic acid of formula 4 because of the instability of some of the prodrugs. Advantageously, the prodrug can be introduced at an earlier stage, provided that it can withstand the reaction conditions of the subsequent steps.

[0158] Bis-phosphoramidates, compounds of formula I wherein both Y's are nitrogen and R¹'s are identical groups derived from amino acids, can be prepared from compounds of formula 4 via the coupling of a suitably activated phosphonate (e.g. dichlorophosphonate) with an amino acid ester (e.g. alanine ethyl ester) with or without the presence of a base (e.g. N-methylimidazole, 4-N,N-dimethylaminopyridine). Alternatively, bis-phosphoramidates can be prepared through reactions between compounds of formula 4 with an amino acid ester (e.g. glycine ethyl ester) in the presence of triphenylphosphine and 2,2'-dipyridyl disulfide in pyridine as described in WO 95/07920 or Mukaiyama, T. et al, J Am. Chem. Soc., 1972, 94, 8528.

[0159] Mixed bis-phosphoramidates, compounds of formula I wherein both Y's are nitrogen and R¹'s are different groups with one R¹ being derived from amino acids and the other R¹ being either derived from amino acids or other groups (e.g. alkyl, aryl, arylalkyl amines), can be prepared by the methods described above but with sequential addition of the different amines (e.g. a glycine ethyl ester and an alanine ethyl ester) to a suitably activated phosphonates (e.g. dichlorophosphonate). It is anticipated that the mixed bis-phosphoramidates may have to be separated from other products (e.g. compounds of formula I wherein both Y's are nitrogen and R¹'s are identical groups) using suitable purification techniques such as column chromatography, MPLC or crystallization methods. Alternatively, mixed bis-phosphoramidates can be prepared in the following manner: coupling of an appropriate phosphonate monoester (e.g. phenyl esters or benzyl esters) with an amine (e.g. alanine ethyl ester or morpholine) via the chloridate method described above, followed by removal of the phosphonate ester (e.g. phenyl esters or benzyl esters) under conditions that the phosphoramidate bond is stable (e.g. suitable hydrogenation conditions), and the resulting mono-phosphoramidate can be coupled with a second amine (e.g. glycine ethyl ester) to give a mixed bis-phosphoramidate via the chloridate method described above. Mono esters of a phosphonic acid can be prepared using conventional methods (e.g. hydrolysis of phosphonate diesters or procedures described in EP 481 214).

[0160] Mono phosphoramidate mono esters, compounds of formula I wherein one Y is O and the other Y is N, can also be prepared using the sequential addition methods described above. For example, a dichloridate generated from compounds of formula 4 can be treated with 0.7 to 1 equivalent of an alcohol (e.g. phenol, benzyl alcohol, 2,2,2-trifluoroethanol) preferably in the presence of a suitable base (e.g. Hunig's base, triethylamine). After the above reaction is completed, 2 to 10 equivalents of an amine (e.g. alanine ethyl ester) is added to the reaction to give compounds of formula I wherein one Y is O and the other Y is N. Alternatively, selective hydrolysis (e.g. using lithium hydroxide) of a phosphonate diester (e.g. a diphenyl phosphonate) can also lead to a phosphonate mono ester (e.g. a phosphonate mono phenyl ester), and the phosphonate mono ester can be coupled with an amine (e.g. alanine ethyl ester) via the chloridate method described above for the preparation of mixed bis-phosphoramidates.

[0161] Compounds of formula 4, can be alkylated with electrophiles (such as alkyl halides, alkyl sulfonates, etc.) under nucleophilic substitution reaction conditions to give phosphonate esters. For example compounds of formula I, wherein R¹ are acyloxyalkyl groups can be synthesized through direct alkylation of compounds of formula 4 with an appropriate acyloxyalkyl halide (e.g. Cl, Br, I; Elhaddadi, et al Phosphorus Sulfur, 1990, 54(1-4): 143; Hoffmann, Synthesis, 1988, 62) in presence of a suitable base (e.g. N, N'-dicyclohexyl-4-morpholinecarboxamidine, Hunig's base etc.) (Starrett, et al, J. Med. Chem., 1994, 1857). The carboxylate component of these acyloxyalkyl halides can be; but is not limited to, acetate, propionate, 2-methylpropionate, pivalate, benzoate, and other carboxylates. When appropriate, further modifications are envisioned after the formation of acyloxyalkyl phosphonate esters such as reduction of a nitro group. For example, compounds of formula 5 wherein J² to J⁶ are each optionally a nitro group can be converted to compounds of formula 5 wherein J² to J⁶ are each optionally an amino group under suitable reduction conditions (Dickson, et al, J. Med. Chem., 1996, 39: 661; Iyer, et al, Tetrahedron Lett., 1989, 30: 7141; Srivastva, et al, Bioorg. Chem., 1984, 12: 118). Compounds of formula I wherein R¹ is a cyclic carbonate, a lactone or a phthalidyl group can also be synthesized via direct alkylation of compounds of formula 4 with appropriate electrophiles (e.g. halides) in the presence of a suitable base (e.g. NaH or diisopropylethylamine, Biller et al., US 5,157,027; Serafinowska et al., J. Med. Chem. 1995, 38: 1372; Starrett et al., J. Med. Chem. 1994, 37: 1857; Martin et aL, J. Pharm. Sci. 1987, 76: 180; Alexander et al., Collect. Czech. Chem. Commun, 1994, 59: 1853; EPO 0632048A1). Other methods can also be used to alkylate compounds of formula 4 (e.g. using N,N-Dimethylformamide dialkyl acetals as alkylating reagents: Alexander, P., et al Collect. Czech. Chem. Commun., 1994, 59, 1853).

[0162] Alternatively, these phosphonate prodrugs can also be synthesized by reactions of the corresponding dichlorophosphonates with an alcohol (Alexander et al, Collect. Czech. Chem. Commun., 1994, 59: 1853). For example, reactions of a dichlorophosphonate with substituted phenols, arylalkyl alcohols in the presence of a suitable base (e.g. pyridine, triethylamine, etc) yield compounds of formula I where R¹ is an aryl group (Khamnei et al., J. Med. Chem., 1996, 39: 4109; Serafinowska et al., J. Med. Chem., 1995, 38: 1372; De Lombaert et al., J. Med Chem., 1994, 37: 498) or an arylalkyl group (Mitchell et al., J. Chem. Soc. Perkin Trans. 1,1992, 38: 2345) and Y is oxygen. The disulfide-containing prodrugs (Puech et al., Antiviral Res., 1993, 22: 155) can also be prepared from a dichlorophosphonate and 2-hydroxyethyl disulfide under standard conditions. When applicable, these methods can be extended to the synthesis of other types of prodrugs, such as compounds of formula I wherein R¹ is a 3-phthalidyl, a 2-oxo-4,5-didehydro-1,3-dioxolanemethyl, or a 2-oxotetrahydrofuran-5-yl group.

[0163] A dichlorophosphonate or a monochlorophosphonate derivative of compounds of formula 4 can be generated from the corresponding phosphonic acids using a chlorinating agent (e.g. thionyl chloride: Starrett et al., J. Med. Chem., 1994, 1857, oxalyl chloride: . Stowell et al., Tetrahedron Lett., 1990, 31: 3261, and phosphorus pentachloride: Quast et al., Synthesis, 1974, 490). Alternatively, a dichlorophosphonate can also be generated from its corresponding disilyl phosphonate esters (Bhongle et al., Synth. Commun., 1987, 17: 1071) or dialkyl phosphonate esters (Still et al., Tetrahedron Lett., 1983, 24: 4405; Patois et al., Bull. Soc. Chim. Fr., 1993, 130: 485).

[0164] Furthermore, when feasible some of these prodrugs can be prepared using Mitsunobu reactions (Mitsunobu, Synthesis, 1981, 1; Campbell, J. Org. Chem., 1992, 52: 6331), and other coupling reactions (e.g. using carbodiimides: Alexander et al., Collect. Czech. Chem. Commun., 1994, 59: 1853; Casara et al., Bioorg. Med. Chem. Lett., 1992, 2: 145; Ohashi et al., Tetrahedron Lett., 1988, 29: 1189, and benzotriazolyloxytris-(dimethylamino)phosphonium salts: Campagne et al., Tetrahedron Lett., 1993, 34: 6743). In some cases R¹ can also be introduced advantageously at an early stage of the synthesis provided that it is compatible with the subsequent reaction steps. For example, compounds of formula I where R¹ is an aryl group can be prepared by metalation of a 2-furanyl substituted heterocycle (e.g. using LDA) followed by trapping the anion with a diaryl chlorophosphate.

[0165] It is envisioned that compounds of formula I can be mixed phosphonate esters (e.g. phenyl and benzyl esters, or phenyl and acyloxyalkyl esters) including the chemically combined mixed esters such as the phenyl and benzyl combined prodrugs reported by Meier, et al. Bioorg. Med. Chem. Lett., 1997, 7: 99.

[0166] The substituted cyclic propyl phosphonate or phosphoramidate esters can be synthesized by reactions of the corresponding dichlorophosphonate with a substituted 1,3-propanediol, 1,3-hydroxypropylamine, or 1,3-propanediamine. Some of the methods useful for preparations of a substituted 1,3-propanediol, for example, are discussed below.

Synthesis of a 1,3-propanediol, 1,3-hydroxypropylamine and 1,3-propanediamine

[0167] Various synthetic methods can be used to prepare numerous types of 1,3-propanediols: (i) 1-substituted, (ii) 2-substituted, (iii) 1,2- or 1,3-annulated 1,3-propanediols, (iv) 1,3-hydroxypropylamine and 1,3-propanediamine. Substituents on the prodrug moiety of compounds of formula I (e.g. substituents on the 1,3-propanediol moiety) can be introduced or modified either during the synthesis of these diols,hydroxyamines, and diamines, or after the coupling of these compounds to the compounds of formula 4.

(i) 1-Substituted 1,3-propanediols.

[0168] 1,3-Propanediols useful for the synthesis of compounds in the present invention can be prepared using various synthetic methods. For example, additions of an aryl Grignard to a 1-hydroxy-propan-3-al give 1-aryl substituted 1,3-propanediols (path a). This method is suitable for the conversion of various aryl halides to 1-aryl substituted-1,3-propanediols (Coppi et. al., J Org. Chem., 1988, 53, 911). Conversions of aryl halides to 1-substituted 1,3-propanediols can also, be achieved using Heck reactions (e.g. couplings with a 1,3-diox-4-ene) followed by reductions and subsequent hydrolysis reactions (Sakamoto et. al., Tetrahedron Lett., 1992, 33, 6845). Various aromatic aldehydes can also be converted to 1-substituted-1,3-propanediols using alkenyl Grignard addition reactions followed by hydroboration reactions (path b). Additions of a t-butyl acetate metal enolate to aromatic aldehydes followed by reduction of the ester (path e) are also useful for the synthesis of 1,3-propanediols (Turner., J. Org. Chem., 1990, 55 4744). In another method, epoxidations of cinnamyl alcohol derivatives using known methods (e.g. Sharpless epoxidations and other asymmetric epoxidation reactions) followed by a reduction reaction (e.g. using Red-Al) give various 1,3-propanediols (path c). Alternatively, enantiomerically pure 1,3-propanediols can be obtained using chiral borane reduction reactions of hydroxyethyl aryl ketone derivatives (Ramachandran et. al., Tetrahedron Lett., 1997, 38 761). Propan-3-ols with a 1-heteroaryl substituent (e.g. a pyridyl, a quinolinyl or an isoquinolinyl) can be oxygenated to give 1-substituted 1,3-propanediols using N-oxide formation reactions followed by a rearrangement reaction in acetic anhydride conditions (path d) (Yamamoto et. al., Tetrahedron, 1981, 37, 1871).

(ii) 2-Substituted 1,3-propanediols:

[0169] A variety of 2-substituted 1,3-propanediols useful for the synthesis of compounds of formula I can be prepared from 2-(hydroxymethyl)-1,3-propanediols using known chemistry (Larock, Comprehensive Organic Transformations, VCH, New York, 1989). For example, reductions of a trialkoxycarbonylmethane under known conditions give a triol via complete reduction (path a) or a bis(hydroxymethyl)acetic acid via selective hydrolysis of one of the ester group followed by reduction of the remaining two other ester groups. Nitrotriols are also known to give triols via reductive elimination (path b) (Latour et. al., Synthesis, 1987, 8, 742). Furthermore, a 2-(hydroxymethyl)-1,3-propanediol can be converted to a mono acylated derivative (e.g. acetyl, methoxycarbonyl) using an acyl chloride or an alkyl chloroformate (e.g. acetyl chloride or methyl chloroformate) (path d) using known chemistry (Greene et al., Protective groups in organic synthesis ; Wiley, New York, 1990). Other functional group manipulations can also be used to prepare 1,3-propanediols such as oxidation of one the hydroxylmethyl group in a 2-(hydroxymethyl)-1,3-propanediol to an aldehyde followed by addition reactions with an aryl Grignard (path c). The intermediate aldehydes can also be converted to alkyl amines via reductive amination reactions (path e).

(iii) Annulated 1,3-propane diols:

[0170] Compounds of formula I wherein V and Z or V and W are connected by four carbons to form a ring can be prepared from a 1,3-cyclohexanediol. For example, cis, cis-1,3,5-cyclohexanetriol can be modified as described for 2-substituted 1,3-propanediols. It is envisioned that these modifications can be performed either before or after formation of a cyclic phosphonate 1,3-propanediol ester. Various 1,3-cyclohexanediols can also be prepared using Diels-Alder reactions (e.g. using a pyrone as the diene: Posner et. al., Tetrahedron Lett., 1991, 32, 5295). 1,3-Cyclohexanediol derivatives are also prepared via other cycloaddition reaction methodologies. For example, cycloadditon of a nitrile oxide to an olefin followed by conversion of the resulting cycloadduct to a 2-ketoethanol derivative which can be converted to a 1,3-cylohexanediol using know chemistry (Curran, et. al., J. Am. Chem. Soc., 1985, 107, 6023). Alternatively, precursors to 1,3-cyclohexanediol can be made from quinic acid (Rao, et. al., Tetrahedron Lett., 1991, 32, 547.)

(vi) Synthesis of chiral substituted 1,3-hydroxyamines and 1,3-diamines:

[0171] Enantiomerically pure 3-aryl-3-hydroxypropan-1-amines are synthesized by CBS enantioselective catalytic reaction of 3-chloropropiophenone followed by displacement of halo group to make secondary or primary amines as required (Corey, et al., Tetrahedron Lett., 1989, 30, 5207). Chiral 3-aryl-3-amino propan-1-ol type of prodrug moiety may be obtained by 1,3-dipolar addition of chirally pure olefin and substituted nitrone of arylaldehyde followed by reduction of resulting isoxazolidine (Koizumi, et al., J. Org. Chem., 1982, 47, 4005). Chiral induction in 1,3-polar additions to form substituted isoxazolidines is also attained by chiral phosphine palladium complexes resulting in enantioselective formation of δ-amino alcohol (Hori, et al., J. Org. Chem., 1999; 64, 5017). Alternatively, optically pure 1-aryl substituted amino alcohols are obtained by selective ring opening of corresponding chiral epoxy alcohols with desired amines (Canas et al., Tetrahedron Lett., 1991, 32, 6931).

[0172] Several methods are known for diastereoselective synthesis of 1,3-disubstituted aminoalcohols. For example, treatment of (E)-N-cinnamyltrichloroacetamide with hypochlorus acid results in trans-dihydrooxazine which is readily hydrolysed to erythro-β-chloro-α-hydroxy-δ-phenylpropanamine in high diastereoselectivity (Commercon et al., Tetrahedron Lett., 1990, 31, 3871). Diastereoselective formation of 1,3-aminoalcohols is also achieved by reductive amination of optically pure 3-hydroxy ketones ( Haddad et al., Tetrahedron Lett., 1997, 38, 5981). In an alternate approach, 3-aminoketones are transformed to 1,3-disubstituted aminoalcohols in high stereoselectivity by a selective hydride reduction (Barluenga et al., J. Org. Chem., 1992, 57, 1219).

[0173] All the above mentioned methods can also be applied to prepare corresponding V-Z, V-W, or V²-Z² annulated chiral aminoalcohols. Furthermore, such optically pure amino alcohols are also a source to obtain optically pure diamines by the procedures described earlier in the section.

Formulations

[0174] Compounds of the invention are administered orally in a total daily dose of about 0.01 mg/kg/dose to about 100 mg/kg/dose, preferably from about 0.1 mg/kg/dose to about 10 mg/kg/dose. The use of time-release preparations to control the rate of release of the active ingredient may be preferred. The dose may be administered in as many divided doses as is convenient. When other methods are used (e.g. intravenous administration), compounds are administered to the affected tissue at a rate from 0.05 to 10 mg/kg/hour, preferably from 0.1 to 1 mg/kg/hour. Such rates are easily maintained when these compounds are intravenously administered as discussed below.

[0175] For the purposes of this invention, the compounds may be administered by a variety of means including orally, parenterally, by inhalation spray, topically, or rectally in formulations containing pharmaceutically acceptable carriers, adjuvants and vehicles. The term parenteral as used here includes subcutaneous, intravenous, intramuscular, and intraarterial injections with a variety of infusion techniques. Intraarterial and intravenous injection as used herein includes administration through catheters. Oral administration is generally preferred.

[0176] Pharmaceutical compositions containing the active ingredient may be in any form suitable for the intended method of administration. When used for oral use for example, tablets, troches, lozenges, aqueous or oil suspensions, dispersible powders or granules, emulsions, hard or soft capsules, syrups or elixirs may be prepared. Compositions intended for oral use may be prepared according to any method known to the art for the manufacture of pharmaceutical compositions and such compositions may contain one or more agents including sweetening agents, flavoring agents, coloring agents and preserving agents, in order to provide a palatable preparation. Tablets containing the active ingredient in admixture with non-toxic pharmaceutically acceptable excipient which are suitable for manufacture of tablets are acceptable. These excipients may be, for example, inert diluents, such as calcium or sodium carbonate, lactose, calcium or sodium phosphate; granulating and disintegrating agents, such as maize starch, or alginic acid; binding agents, such as starch, gelatin or acacia; and lubricating agents, such as magnesium stearate, stearic acid or talc. Tablets may be uncoated or may be coated by known techniques including microencapsulation to delay disintegration and adsorption in the gastrointestinal tract and thereby provide a sustained action over a longer period. For example, a time delay material such as glyceryl monostearate or glyceryl distearate alone or with a wax may be employed .

[0177] Formulations for oral use may be also presented as hard gelatin capsules where the active ingredient is mixed with an inert solid diluent, for example calcium phosphate or kaolin, or as soft gelatin capsules wherein the active ingredient is mixed with water or an oil medium, such as peanut oil, liquid paraffin or olive oil.

[0178] Aqueous suspensions of the invention contain the active materials in admixture with excipients suitable for the manufacture of aqueous suspensions. Such excipients include a suspending agent, such as sodium carboxymethylcellulose, methylcellulose, hydroxypropyl methylcellulose, sodium alginate, polyvinylpyrrolidone, gum tragacanth and gum acacia, and dispersing or wetting agents such as a naturally occurring phosphatide (e.g., lecithin), a condensation product of an alkylene oxide with a fatty acid (e.g., polyoxyethylene stearate), a condensation product of ethylene oxide with a long chain aliphatic alcohol (e.g., heptadecaethyleneoxycetanol), a condensation product of ethylene oxide with a partial ester derived from a fatty acid and a hexitol anhydride (e.g., polyoxyethylene sorbitan monooleate). The aqueous suspension may also contain one or more preservatives such as ethyl or n-propyl p-hydroxy-benzoate, one or more coloring agents, one or more flavoring agents and one or more sweetening agents, such as sucrose or saccharin.

[0179] Oil suspensions may be formulated by suspending the active ingredient in a vegetable oil, such as arachis oil, olive oil, sesame oil or coconut oil, or in a mineral oil such as liquid paraffin. The oral suspensions may contain a thickening agent, such as beeswax, hard paraffin or cetyl alcohol. Sweetening agents, such as those set forth above, and flavoring agents may be added to provide a palatable oral preparation. These compositions may be preserved by the addition of an antioxidant such as ascorbic acid.

[0180] Dispersible powders and granules of the invention suitable for preparation of an aqueous suspension by the addition of water provide the active ingredient in admixture with a dispersing or wetting agent, a suspending agent, and one or more preservatives. Suitable dispersing or wetting agents and suspending agents are exemplified by those disclosed above. Additional excipients, for example sweetening, flavoring and coloring agents, may also be present.

[0181] The pharmaceutical compositions of the invention may also be in the form of oil-in-water emulsions. The oily phase may be a vegetable oil, such as olive oil or arachis oil, a mineral oil, such as liquid paraffin, or a mixture of these. Suitable emulsifying agents include naturally-occurring gums, such as gum acacia and gum tragacanth, naturally occurring phosphatides, such as soybean lecithin, esters or partial esters derived from fatty acids and hexitol anhydrides, such as sorbitan monooleate, and condensation products of these partial esters with ethylene oxide, such as polyoxyethylene sorbitan monooleate. The emulsion may also contain sweetening and flavoring agents.

[0182] Syrups and elixirs may be formulated with sweetening agents, such as glycerol, sorbitol or sucrose. Such formulations may also contain a demulcent, a preservative; a flavoring or a coloring agent.

[0183] The pharmaceutical compositions of the invention may be in the form of a sterile injectable preparation, such as a sterile injectable aqueous or oleaginous suspension. This suspension may be formulated according to the known art using those suitable dispersing or wetting agents and suspending agents which have been mentioned above. The sterile injectable preparation may also be a sterile injectable solution or suspension in a non-toxic parenterally acceptable diluent or solvent, such as a solution in 1,3-butane-diol or prepared as a lyophilized powder. Among the acceptable vehicles and solvents that may be employed are water, Ringer's solution and isotonic sodium chloride solution. In addition, sterile fixed oils may conventionally be employed as a solvent or suspending medium. For this purpose any bland fixed oil may be employed including synthetic mono- or diglycerides. In addition, fatty acids such as oleic acid may likewise be used in the preparation of injectables.

[0184] The amount of active ingredient that may be combined with the carrier material to produce a single dosage form will vary depending upon the host treated and the particular mode of administration. For example, a time-release formulation intended for oral administration to humans may contain approximately 1 to 1000 mg of active material compounded with an appropriate and convenient amount of carrier material which may vary from about 5 to about 95% of the total compositions. The pharmaceutical composition can be prepared to provide easily measurable amounts for administration. For example, an aqueous solution intended for intravenous infusion should contain from about 3 to 330 µg of the active ingredient per milliliter of solution in order that infusion of a suitable volume at a rate of about 30 mL/hr can occur.

[0185] As noted above, formulations of the present invention suitable for oral administration may be presented as discrete units such as capsules, cachets or tablets each containing a predetermined amount of the active ingredient; as a powder or granules; as a solution or a suspension in an aqueous or non-aqueous liquid; or as an oil-in-water liquid emulsion or a water-in-oil liquid emulsion. The active ingredient may also be administered as a bolus, electuary or paste.

[0186] A tablet may be made by compression or molding, optionally with one or more accessory ingredients. Compressed tablets may be prepared by compressing in a suitable machine the active ingredient in a free flowing form such as a powder or granules, optionally mixed with a binder (e.g., povidone, gelatin, hydroxypropylmethyl cellulose), lubricant, inert diluent, preservative, disintegrant (e.g., sodium starch glycolate, cross-linked povidone, cross-linked sodium carboxymethyl cellulose) surface active or dispersing agent. Molded tablets may be made by molding in a suitable machine a mixture of the powdered compound moistened with an inert liquid diluent. The tablets may optionally be coated or scored and may be formulated so as to provide slow or controlled release of the active ingredient therein using, for example, hydroxypropyl methylcellulose in varying proportions to provide the desired release profile. Tablets may optionally be provided with an enteric coating, to provide release in parts of the gut other than the stomach. This is particularly advantageous with the compounds of formula I when such compounds are susceptible to acid hydrolysis.

[0187] Formulations suitable for topical administration in the mouth include lozenges comprising the active ingredient in a flavored base, usually sucrose and acacia or tragacanth; pastilles comprising the active ingredient in an inert base such as gelatin and glycerin, or sucrose and acacia; and mouthwashes comprising the active ingredient in a suitable liquid carrier.

[0188] Formulations for rectal administration may be presented as a suppository with a suitable base comprising for example cocoa butter or a salicylate.

[0189] Formulations suitable for vaginal administration may be presented as pessaries, tampons, creams, gels, pastes, foams or spray formulations containing in addition to the active ingredient such carriers as are known in the art to be appropriate.

[0190] Formulations suitable for parenteral administration include aqueous and non-aqueous isotonic sterile injection solutions which may contain antioxidants, buffers, bacteriostats and solutes which render the formulation isotonic with the blood of the intended recipient; and aqueous and non-aqueous sterile suspensions which may include suspending agents and thickening agents. The formulations may be presented in unit-dose or multi-dose sealed containers, for example, ampoules and vials, and may be stored in a freeze-dried (lyophilized) condition requiring only the addition of the sterile liquid carrier, for example water for injections, immediately prior to use. Injection solutions and suspensions may be prepared from sterile powders, granules and tablets of the kind previously described.

[0191] Suitable unit dosage formulations are those containing a daily dose or unit, daily sub-dose, or an appropriate fraction thereof, of a fructose-1,6-bisphosphatase inhibitor compound.

[0192] It will be understood, however, that the specific dose level for any particular patient will depend on a variety of factors including the activity of the specific compound employed; the age, body weight, general health, sex and diet of the individual being treated; the time and route of administration; the rate of excretion; other drugs which have previously been administered; and the severity of the particular disease undergoing therapy, as is well understood by those skilled in the art.

Utility

[0193] FBPase inhibitors may be used to treat diabetes mellitus, lower blood glucose levels, and inhibit gluconeogenesis.

[0194] FBPase inhibitors may also be used to treat excess glycogen storage diseases. Excessive hepatic glycogen stores are found in patients with some glycogen storage diseases. Since the indirect pathway contributes significantly to glycogen synthesis (Shulman, G.I. Phys. Rev. 72:1019-1035 (1992)), inhibition of the indirect pathway (gluconeogenesis flux) decreases glycogen overproduction.

[0195] FBPase inhibitors may also be used to treat or prevent diseases associated with increased insulin levels. Increased insulin levels are associated with an increased risk of cardiovascular complications and atherosclerosis (Folsom, et al., Stroke, 25:66-73 (1994); Howard, G. et al., Circulation 93:1809-1817 (1996)). FBPase inhibitors are expected to decrease postprandial glucose levels by enhancing hepatic glucose uptake. This effect is postulated to occur in individuals that are non-diabetic (or pre-diabetic, i.e. without elevated hepatic glucose output "hereinafter HGO" or fasting blood glucose levels). Increased hepatic glucose uptake will decrease insulin secretion and thereby decrease the risk of diseases or complications that arise from elevated insulin levels.

[0196] One aspect of the invention is directed to the use of prodrugs of the novel aryl phosphonates or phosphoramidates which results in efficient conversion of the cyclic phosphonate or phosphoramidate. The cyclic 1,3-propanyl ester containing compounds are oxidized by p450 enzymes found in large amounts in the liver and other tissues containing these specific enzymes.

[0197] In another aspect of the invention, these prodrugs can also be used to prolong the pharmacodynamic half-life because the cyclic phosphonates or phosphoramidatess of the invention can prevent the action of enzymes which degrade the parent drug.

[0198] In another aspect of the invention, these prodrugs can be used to achieve sustained delivery of the parent drug because various novel prodrugs are slowly oxidized in the liver at different rates.

[0199] The novel cyclic 1,3-propanyl esters of the present invention may also be used to increase the distribution of a particular drug to the liver which contains abundant amounts of the p450 isozymes responsible for oxidizing the cyclic 1,3-propanyl ester of the present invention so that the free phosphonate or phosphoramidate is produced.

[0200] In another aspect of the invention, the cyclic phosphonate or phosphoramidate prodrugs can increase the oral bioavailability of the drugs.

[0201] Theses aspects are described in greater detail below.

[0202] Evidence of the liver specificity can also be shown in vivo after both oral and I.V. administration of the prodrugs as described in Examples G and H.

Prodrug Cleavage Mechanism of Cyclic 1,3-propgayl esters

[0203] The cyclic 1,3-propanyl ester prodrugs are rapidly cleaved in the presence of liver microsomes from rates and humans, by freshly isolated rat hepatocyles, and by cytochrome P450 inhibitors. It is believed that the isoenzyme cytochrome CYP3A4 is responsible for the oxidation based on ketoconozole inhibition of drug formation. Inhibitors of cytochrome P450 family 1 and/or family 2 do not appear to inhibit prodrug cleavage. Furthermore, although these specific prodrugs appear to be cleaved by CYP3A4, other prodrugs in the class may be substrates for other P450s.

[0204] Although the cyclic 1,3-propanyl esters in the invention are not limited by the above mechanisms, in general, each ester contains a group or atom susceptible to microsomal oxidation (e.g. alcohol, benzylic methine proton), which in turn generates an intermediate that breaks down to the parent compound in aqueous solution via β-elimination of the phosphonate or phosphoramidate diacid.

[0205] Class (1) prodrugs readily undergo P450 oxidation because they have a Z' = hydroxyl or hydroxyl equivalent with an adjacent (geminal) acidic proton. D' is hydrogen to allow the ultimate elimination to produce a phenol.

[0206] Class (2) generally has V is selected from group consisting of aryl, substituted aryl, heteroaryl, substituted heteroaryl, 1-alkenyl, and 1-alkynyl. This class of prodrugs readily undergoes P450 oxidation at the benzylic methine proton (the proton on the carbon to which V is attached). The allylic proton in the case of 1-alkenyl and 1-alkynl behaves similarly. There must be a hydrogen geminal to V to undergo this oxidation mechanism. Because Z, W, and W' are not at the oxidation site in this class of prodrugs, a broad range of substituents are possible. In one aspect, Z can be an electron donating group which may reduce the mutagenicity or toxicity of the arylvinyl ketone that is the by-product of the oxidation of this class of prodrugs. Thus, in this aspect Z is -OR², -SR², or -NR²₂.

[0207] In this class of prodrug, V and W may be cis to one another or trans to one another. The class (2) mechanism generally describes the oxidation mechanism for cyclic 1,3-propanyl esters wherein together V and Z are connected via an additional 3-5 atoms to form a cyclic group, optionally containing 1 heteroatom, said cyclic group is fused to an aryl group at the beta and gamma position to the Y adjacent to V.

[0208] Class (3) includes compounds wherein Z² is selected from the group consisting of -CHR²OH, -CHR²OC(O)R³, -CHR²OC(S)R³, -CHR²OC(S)OR³, -CHR²OC(O)SR³, - CHR²OCO₂R³, -SR², -CHR²N₃, -CH₂aryl, -CH(aryl)OH, -CH(CH=CR²₂)OH, -CH(C CR²)OH, and -CH₂NHaryl.

[0209] Class (3) prodrugs readily undergo P450 oxidation because Z² contains a hydroxyl or hydroxyl equivalent (e.g., -CHR²OC(O)R³, -CHR²N₃) with an adjacent (geminal) acidic proton. Z² groups may also readily undergo P450 oxidation because they have a benzylic methine proton or equivalent (e.g., -CH₂aryl, -CH(CH=CR²₂)OH). Where Z² is -SR², it is believed that this is oxidized to the sulfoxide or sulfone which will enhance the beta-elimination step. Where Z² is -CH₂NHaryl, the carbon next to nitrogen is oxidized to produce a hemiaminal, which hydrolizes to the aldehyde (-C(O)H), as shown above for class (3). Because V², W², and W" are not at the oxidation site in this class of prodrugs, a broad range of V², W², and W" substituents is possible.

[0210] The Class (3) mechanism depicted above generally describes the oxidaton mechanism for cyclic 1,3-propanyl esters wherein together V² and Z² are connected via an additional 3-5 atoms to form a cylic group containing 5-7 atoms, optionally 1 heteroatom, substituted with hydroxy, acyloxy, alkoxycarbonyloxy, or aryloxycarbonyloxy attached to a carbon that is three atoms from both Y groups attached to the phosphorus. This class of prodrugs undergoes P450 oxidation and oxidizes by a mechanism analogous to those of class (3) described above. The broad range of W' and W groups are suitable.

[0211] The mechanism of cleavage could proceed by the following mechanisms. Further evidence for these mechanisms is indicated by analysis of the by-products of cleavage. Prodrugs of class (1) depicted where Y is -O- generate phenol whereas prodrugs of class (2) depicted where Y is -O- generate phenyl vinyl ketone.

[0212] The cyclic phosphoramidates where Y is a nitrogen rather than oxygen containing moiety can serve as a prodrug since intermediate phosphoramidates can generate the intermediate phosphonate or phosphoramidate by a similar mechanism. The phosphoramidate (-P(O)(NH₂)O^-) is then converted to the phosphonate (-PO₃^2-).

Inhibition of Rat Liver FBPase

[0264] E. coli strain BL21 transformed with a rat liver FBPase-encoding plasmid is obtained from Dr. M.R. E1-Maghrabi at the State University of New York at Stony Brook. Recombinant FBPase is purified as described (E1-Maghrabi, M.R., and Pilkis, S.J. (1991) Biochem. Biophys. Res. Commun. 176, 137-144) The enzyme assay is identical to that described above for human liver FBPase. The IC₅₀ for AMP is 20 µM.

Example B: AMP Site Binding

[0265] To assess whether compounds bind to the allosteric AMP binding site of hIFBPase, the enzyme is incubated with radio-labeled AMP in the presence of a range of test compound concentrations. The reaction mixtures consist of 25 mM ³H-AMP (54 mCi/mmole) and 0 - 1000 mM test compound in 25 mM Tris-HCl, pH 7.4, 100 mM KCl and 1 mM MgCl₂. 1.45 mg of homogeneous FBPase (±1 nmole) is added last. After a 1 minute incubation, AMP bound to FBPase is separated from unbound AMP by means of a centrifugal ultrafiltration unit ("Ultrafree-MC", Millipore) used according to the instructions of the manufacturer. The radioactivity in aliquots (100 µl) of the upper compartment of the unit (the retentate, which contains enzyme and label) and the lower compartment (the filtrate, which contains unbound label) is quantified using a Beckman liquid scintillation counter. The amount of AMP bound to the enzyme is estimated by comparing the counts in the filtrate (the unbound label) to the total counts in the retentate.

Example C: AMP Site/Enzyme Selectivity

[0266] To determine the selectivity of compounds towards FBPase, effects of FBPase inhibitors on 5 key AMP binding enzymes is measured using the assays described below: Adenosine Kinase: Human adenosine kinase is purified from an E. coli expression system as described by Spychala et al. (Spychala, J., Datta, N.S., Takabayashi, K., Datta, M., Fox, I.H., Gribbin, T., and Mitchell, B.S. (1996) Proc. Natl. Acad. Sci. USA 93, 1232-123'7). Activity was measured essentially as described by Yamada et al. (Yamada, Y., Goto, H., Ogasawara, N. (1988) Biochim. Biophys. Acta 660, 36-43.) with a few minor modifications. Assay mixtures contain 50 mM TRIS-maleate buffer, pH 7.0, 0.1% BSA, 1 mM ATP 1 mM MgCl₂, 1.0 µM [U-¹⁴C] adenosine (400-600 mCi/mmol) and varying duplicate concentrations of inhibitor. ¹⁴C-AMP was separated from unreacted ¹⁴C-adenosine by absorption to anion exchange paper (Whatman) and quantified by scintillation counting.

[0267] Adenosine Monophosphate Deaminase: Porcine heart AMPDA is purified essentially as described by Smiley et al. (Smiley, K.L., Jr, Berry, A.J., and Suelter, C.H. (1967) J. Biol. Chem. 242, 2502-2506) through the phosphocellulose step. Inhibition of AMPDA activity is determined at 37 °C in a 0.1 ml assay mixture containing inhibitor, ~0.005U AMPDA, 0.1% bovine serum albumin, 10 mM ATP, 250 mM KCl, and 50 mM MOPS at pH 6.5. The concentration of the substrate AMP is varied from 0.125 - 10.0 mM. Catalysis is initiated by the addition of enzyme to the otherwise complete reaction mixture, and terminated after 5 minutes by injection into an HPLC system. Activities are determined from the amount of IMP formed during 5 minutes. IMP is separated from AMP by HPLC using a Beckman Ultrasil-SAX anion exchange column (4.6 mm x 25 cm) with an isocratic buffer system (12.5 mM potassium phosphate, 30 mM KCl, pH 3.5) and detected spectrophotometrically by absorbance at 254 nm.

[0268] Phosphofructokinase: Enzyme (rabbit liver) is purchased from Sigma. Activity is measured at 30 °C in reactions in which the formation of fructose-1,6-bisphosphate is coupled to the oxidation of NADH via the action of aldolase, triosephosphate isomerase, and α-glycerophosphate dehydrogenase.

[0269] Glycogen Phosphorylase: Enzyme (rabbit muscle) is purchased from Sigma. Activity is measured at 37 °C in reactions in which the formation of glucose 1-phosphate is coupled to the reduction of NADP via phosphoglucomutase and glucose 6-phosphate dehydrogenase. Assays are performed on 96-well microtitre plates and are read at 340 nm on a Molecular Devices Microplate Reader. Reaction mixtures consist of 20 mM imidazole, pH 7.4, 20 mM MgCl₂, 150 mM potassium acetate, 5 mM potassium phosphate, 1 mM DTT, 1 mg/ml BSA, 0.1 mM NADP, 1 unit/ml phosphoglucomutase, 1 unit/ml glucose 6-phosphate dehydrogenase, 0.5% glycogen. Test compound concentrations range from 1 to 500 µM. Reactions are started by the addition of 17 µg enzyme and are monitored for 20 minutes.

[0270] Adenylate Kinase: Enzyme (rabbit muscle) is purchase from Sigma. Activity is measured at 37 °C in reaction mixtures (100 µl) containing 100 mM Hepes, pH 7.4, 45 mM MgCl₂, 1 mM EGTA, 100 mM KCl, 2 mg/ml BSA, 1 mM AMP and 2 mM ATP. Reactions are started by addition of 4.4 ng enzyme and terminated after 5 minutes by addition of 17 µl perchloric acid. Precipitated protein is removed by centrifugation and the supernatant neutralized by addition of 33 µl 3 M KOH/3 M KHCO₃. The neutralized solution is clarified by centrifugation and filtration and analyzed for ADP content (enzyme activity) by HPLC using a YMC ODS AQ column (25 X 4.6 cm). A gradient is run from 0.1 M KH₂PO₄, pH 6, 8 mM tetrabutyl ammonium hydrogen sulfate to 75% acetonitrile. Absorbance is monitored at 254 nM.

Example D: Inhibition of Gluconeogenesis in Rat Hepatocytes

[0271] Hepatocytes are prepared from overnight fasted Sprague-Dawley rats (250-300 g) according to the procedure of Berry and Friend (Berry, M.N., Friend, D.S., 1969, J. Cell. Biol. 43, 506-520) as modified by Groen (Groen, A.K., Sips, H.J., Vervoorn, RC., Tager, J.M. , 1982, Eur. J. Biochem. 122, 87-93). Hepatocytes (75 mg wet weight/ml) are incubated in 1 ml Krebs-bicarbonate buffer containing 10 mM Lactate, 1 mM pyruvate, 1 mg/ml BSA, and test compound concentrations from 1 to 500 µM. Incubations are carried out in a 95% oxygen, 5% carbon dioxide atmosphere in closed, 50-ml Falcon tubes submerged in a rapidly shaking water bath (37°C). After 1 hour, an aliquot (0.25 ml) is removed, transferred to an Eppendorf tube and centrifuged. 50 µl of supernatant is then assayed for glucose content using a Sigma Glucose Oxidase kit as per the manufacturer's instructions.

Example E: Glucose Production Inhibition and Fructose-1,6-bisphosphate Accumulation in Rat Hepatocytes

[0272] Isolated rat hepatocytes are prepared as described in Example D and incubated under the identical conditions described. Reactions are terminated by removing an aliquot (250 µl) of cell suspension and spinning it through a layer of oil (0.8 ml silicone/mineral oil, 4/1) into a 10% perchloric acid layer (100 µl). After removal of the oil layer, the acidic cell extract layer is neutralized by addition of 1/3rd volume of 3 M KOH/3 M KHCO₃. After thorough mixing and centrifugation, the supernatant is analyzed for glucose content as described in Example D, and also for fructose-1,6-bisphosphate. Fructose-1,6-bisphosphate is assayed spectrophotometrically by coupling its enzymatic conversion to glycerol 3-phosphate to the oxidation of NADH, which is monitored at 340 nm. Reaction mixtures (1 ml) consist of 200 mM Tris-HCl, pH 7.4, 0.3 mM NADH, 2 units/ml glycerol 3-phosphate dehydrogenase, 2 units/ml triosephosphate isomerase, and 50-100 µl cell extract. After a 30 minute preincubation at 37 °C, 1 unit/ml of aldolase is: added and the change in absorbance measured until a stable value is obtained. 2 moles of NADH are oxidized in this reaction per mole of fructose-1,6-bisphosphate present in the cell extract

[0273] A dose-dependent inhibition of glucose production accompanied by a dose-dependent accumulation of fructose-1,6 bisphosphate (the substrate of FBPase) is an indication that the target enzyme in the gluconeogenic pathway, FBPase, is inhibited.

Example F: Blood Glucose Lowering Following Intravenous Administration to Fasted Rats

[0274] Sprague Dawley rats (250-300 g) are fasted for 18 hours and then dosed intravenously either with saline or up to about 60 mg/kg of an FBPase inhibitor. Inhibitors are dissolved in water and the solution adjusted to neutrality with NaOH. Blood samples are obtained from the tail vein of conscious animals just prior to injection and after 1 hour. Blood glucose is measured using a HemoCue Inc. glucose analyzer according to the instructions of the manufacturer.

Example G: Analysis of Drug Levels and Liver Accumulation in Rats

[0275] Sprague-Dawley rats (250-300 g) are fasted for 18 hours and then dosed intravenously either with saline up to about 60 mgs/kg of a compound of the invention. The compound is dissolved in water and the solution adjusted to neutrality with NaOH. One hour post injection rats are anesthetized with halothane and a liver biopsy (approx. 1 g) is taken as well as a blood sample (2 ml) from the posterior vena cava. A heparin flushed syringe and needle are used for blood collection. The liver sample is immediately homogenized in ice-cold 10% perchloric acid (3 ml), centrifuged, and the supernatant neutralized with 1/3rd volume of 3 M KOH/3 M KHCO₃. Following centrifugation and filtration, 50 µl of the neutralized extract is analyzed for compound content by HPLC. A YMC ODS AQ column (250 X 4.6 cm) is used and eluted with a gradient from 10 mM sodium phosphate pH 5.5 to 75% acetonitrile. Absorbance is monitored at 310 - 325 nm. Plasma is prepared from the blood sample by centrifugation and extracted by addition of methanol to 60% (v/v). The methanolic extract is clarified by centrifugation and filtration and then analyzed by HPLC as described above.

Example H: Glucose Lowering Following Oral Administration to the Fasted Rat

[0276] Compounds are administered by oral gavage to 18-hour fasted, Sprague Dawley rats (250-300g). Phosphonic acids are prepared in deionized water, and the solution adjusted to neutrality with sodium hydroxide. Prodrugs are dissolved in polyethylene glycol (mw 400). Blood glucose is measured immediately prior to dosing and at 1 hour intervals thereafter by means of a HemoCue glucose analyzer (HemoCue Inc., Mission Viejo, CA).

Example I: Estimation of the Oral Bioavailability of Phosphonic Acids and Their Prodrugs

[0277] Phosphonic acids are dissolved in water, and the solution adjusted to neutrality with sodium hydroxide. Prodrugs are dissolved in 10% ethanol/90% polyethlene glycol (mw 400). Compound is administered by oral gavage to 18-hour fasted Sprague-Dawley rats (220-250 g) at doses ranging from 10-60 mg/kg. The rats are subsequently placed in metabolic cages and urine is collected for 24 hours. The quantity ofphosphonic acid excreted into urine is determined by HPLC analysis as described in Example G. In a separate study, urinary recovery is determined following intravenous (tail vein) administration of compound (in the case of the prodrugs, the appropriate parent phosphonic acid is administered I.V.). The percentage oral bioavailability is estimated by comparison of the recovery of compound in urine 24 hours following oral administration, to that recovered in urine 24 hours after intravenous administration.

Example J: Blood Glucose Lowering in Zucker Diabetic Fatty Rats, Oral

[0278] Zucker Diabetic Fatty rats are purchased from Genetics Models Inc. (Indianapolis, Indiana) at 8 weeks of age and fed the recommended Purina 5008 diet. At the age of 12 weeks, 16 animals with fed blood glucose levels between 500 and 700 mg/dl are selected and divided into two groups (n=8) with statistically equivalent average blood glucose levels. A compound of the invention is administered at a dose of up to about 300 mg/kg by oral gavage to one group of animals at 1 p.m. The drug solution for this treatment is prepared in deionized water and adjusted to neutrality by dropwise addition of 5 N NaOH. A second group of rats (n=8) is dosed orally with saline, in parallel. Blood glucose is measured in each rat just prior to drug or saline administration and 6 hours post administration. A HemoCue blood glucose analyzer (HemoCue Inc., Mission Viejo, CA) is used for these measurements according to the manufacturer's instructions.

Example K: Blood Glucose Lowering in Zucker Diabetic Fatty Rats, Intravenous

[0279] 12-week old Zucker Diabetic Fatty rats (Genetics Models Inc., Indianapolis, Indiana) maintained on Purina 5008 diet are instrumented with tail artery and tail vein catheters at 8 am on the day of the study. Food is removed for the remainder of the day. Starting at 12 p.m., animals are infused for 6 hours via the tail vein catheter either with saline or compound of the invention at up to about 60 mg/kg/h. Blood samples are obtained from the tail artery catheter at the start of the infusions, and at hourly intervals thereafter. Glucose is measured in the samples by means of a HemoCue analyzer (HemoCue Inc., Mission Viejo, CA) according to the manufacturer's instructions.

Example L: Inhibition of Gluconeogenesis by FBPase Inhibitor in Zucker Diabetic Fatty Rats

[0280] Following a 6-hour infusion of a compound of the invention at up to about 60 mg/kg/h or saline to Zucker Diabetic Fatty rats (n=3/group) as described in Example K, a bolus of ¹⁴C-bicarbonate (40 µCi/100g body weight) is administered via the tail vein catheter. 20 minutes later, a blood sample (0.6 mL) is taken via the tail artery. Blood (0.5 ml) is diluted into 6 mL deionized water and protein precipitated by addition of 1 mL zinc sulfate (0.3 N) and 1 mL barium hydroxide (0.3 N). The mixture is centrifuged (20 minutes, 1000 X g) and 5 mL of the resulting supernatant is then combined with 1 g of a mixed bed ion exchange resin (1 part AG 50W-X8, 100-200 mesh, hydrogen form, and 2 parts AG 1-X8, 100-200 mesh, acetate form) to separate ¹⁴-C-bicabonate from ¹⁴C-glucose. The slurry is shaken at room temperature for four hours and then allowed to settle. An aliquot of the supernatant (0.5 mL) is then counted in 5 mL scintillation cocktail. The percentage inhibition of gluconeogenesis in drug-treated rats is calculated by dividing the average cpm of ¹⁴C-glucose in samples from drug-treated animals by those from saline-injected animals.

[0281] Inhibition ¹⁴C-Glucose production provides evidence that the glucose lowering activity in the Zucker Diabetic Fatty rat (Example K) is due to the inhibition of gluconeogenesis.

Example M: Blood Glucose Lowering in the Streptozotocin-Treated Rat

[0282] Diabetes is induced in male Sprague-Dawley rats (250-300 g) by intraperitoneal injection of 55 mg/kg streptozotocin (Sigma Chemical Co.). Six days later, blood glucose is measured as described in Example F. Animals are selected with fed blood glucose values (8 am) between 350 and 600 mg/dl, and divided into two groups. One group is dosed orally with compound (up to about 300 mg/kg) and the second with an equivalent volume of saline. Food is removed from the animals. Blood glucose is measured again after 2 and 4 hours of drug/saline administration.

Example N: Oral Absorption Determinations of Prodrugs in the Rat

[0283] Prodrugs of the invention are administered to normal, fed rats at 30 mg/kg both by intraperitoneal injection and by oral gavage (n=3 rats/ compound/route of administration). Rats are subsequently placed in metabolic cages and urine collected for 24 hours. Parent compound, is quantitated in urine by reverse phase HPLC as described in Example G. By comparison of the amount of parent compound excreted in urine following oral administration to that following intraperitoneal administration, the % oral absorption is calculated for each prodrug.

Example O: Chronic Oral Efficacy in the ZDF Rat

[0284] To determine the chronic glucose lowering effects of a prodrug of the invention, ZDF are administered the drug orally for 3 weeks.

[0285] Methods: ZDF rats (10 weeks of age) are maintained either on powdered Purina 5008 rat chow (n=10) or the same powdered chow supplemented with 1% of the drug (n=8). Blood glucose measurements are made as described in Example F at baseline and at weekly intervals thereafter for a total of 3 weeks. Statistical analysis is performed using the Student's t test.

Example P: Identification of the P450 Isozyme Involved in the Activation

[0286] Prodrugs are evaluated for human microsome-catalyzed conversion to parent compound in the absence and presence of specific inhibitors of three major P450 isozymes: ketoconazole (CYP3A4), furafylline (CYP1A2), and sulfaphenazole (CYP2C9).

[0287] Methods: Reaction (0.5 ml @ 37°C) consist of 0.2 M KH₂PO₄, 13 mM glucose-6-phosphate, 2.2 mM NADP⁺, 1 unit of glucose-6-phosphate dehydrogenase, 0-2.5 mg/ml human microsomal protein (In Vitro Technologies, In.), 250µ prodrug, and 0-100 µM P450 isozyme inhibitor: Reactions are stopped by addition of methanol to a concentration of 60%, filtered (0.2 µM filter), and lyophilized. Samples are resuspended in HPLC buffer (10 mM phosphate pH 5.5, 2.5 mM octyl-triethylammonium), loaded onto a YMC C8 HPLC column (250 x 4.6 mm), and eluted with a methanol gradient to 80%. Formuation of parent drug is confirmed by co-elution with an authentic parent drug standard.

[0288] Results: Prodrug is converted readily to parent drug in human liver microsomes. Ketoconazole will inhibit the formation of parent drugs in a dose-dependent fashion. The other inhibitor, fusafylline and sulfaphenazole, will show no significant inhibition. The results indicate that CYP3A4 is the primary P450 isoform responsible for activation of prodrugs in human liver.
