CROSS REFERENCES TO RELATED APPLICATIONS
FIELD OF THE INVENTION
[0002] The present invention relates to compounds that inhibit myeloid cell leukemia 1 protein
(Mcl-1, also abbreviated as MCl-1, MCL-1 or MCL1); methods of treating diseases or
conditions, such as cancer, using the compounds; and pharmaceutical compositions containing
the compounds.
BACKGROUND OF THE INVENTION
[0003] One common characteristic of human cancer is overexpression of Mcl-1. Mcl-1overexpression
prevents cancer cells from undergoing programmed cell death (apoptosis), allowing
the cells to survive despite widespread genetic damage.
[0004] Mcl-1 is a member of the Bcl-2 family of proteins. The Bcl-2 family includes pro-apoptotic
members (such as BAX and BAK) which, upon activation, form a homo-oligomer in the
outer mitochondrial membrane that leads to pore formation and the escape of mitochondrial
contents, a step in triggering apoptosis. Antiapoptotic members of the Bcl-2 family
(such as Bcl-2, Bcl-XL, and Mcl-1) block the activity of BAX and BAK. Other proteins
(such as BID, BIM, BIK, and BAD) exhibit additional regulatory functions.
[0006] New compositions and methods for preparing and formulating Mcl-1 inhibitors would
be useful.

DETAILED DESCRIPTION
[0015] The symbol "-" represents a covalent bond and can also be used in a radical group
to indicate the point of attachment to another group. In chemical structures, the
symbol - is commonly used to represent a methyl group in a molecule.
[0016] As used herein, chemical structures which contain one or more stereocenters depicted
with dashed and bold bonds (i.e.,

and

) are meant to indicate absolute stereochemistry of the stereocenter(s) present in
the chemical structure. As used herein, bonds symbolized by a simple line do not indicate
a stereo-preference. Unless otherwise indicated to the contrary, chemical structures
that include one or more stereocenters which are illustrated herein without indicating
absolute or relative stereochemistry encompass all possible stereoisomeric forms of
the compound (e.g., diastereomers, enantiomers) and mixtures thereof. Structures with
a single bold or dashed line, and at least one additional simple line, encompass a
single enantiomeric series of all possible diastereomers.
[0017] As used herein, the term "about" is meant to account for variations due to experimental
error. All measurements reported herein are understood to be modified by the term
"about," whether or not the term is explicitly used, unless explicitly stated otherwise.
As used herein, the singular forms "a," "an," and "the" include plural referents unless
the context clearly dictates otherwise.
[0018] The term "alkyl" means a straight or branched chain hydrocarbon. Representative examples
of alkyl groups include methyl, ethyl, propyl, isopropyl, butyl, isobutyl, tert-butyl,
sec-butyl, pentyl and hexyl. Typical alkyl groups are alkyl groups having from 1 to
8 carbon atoms, which groups are commonly represented as C
1-8 alkyl.
[0019] The term "compound", as used herein is meant to include all stereoisomers, geometric
isomers, tautomers, and isotopes of the structures depicted. Compounds herein identified
by name or structure as one particular tautomeric form are intended to include other
tautomeric forms unless otherwise specified.
[0020] All compounds, and pharmaceutically acceptable salts thereof, can be found together
with other substances such as water and solvents (e.g., hydrates and solvates).
[0021] The term "cycloalkyl" means a cyclic, nonaromatic hydrocarbon. Representative examples
of cycloalkyl groups include cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl and
cycloheptyl. A cycloalkyl group can contain one or more double bonds. Representative
examples of cycloalkyl groups that contain double bonds include cyclopentenyl, cyclohexenyl,
cyclohexadienyl and cyclobutadienyl. Common cycloalkyl groups are C
3-8 cycloalkyl groups.
[0022] The term "excipient", as used herein, means any pharmaceutically acceptable additive,
carrier, diluent, adjuvant or other ingredient, other than the active pharmaceutical
ingredient (API), which is typically included for formulation and/or administration
to a patient.
Handbook of Pharmaceutical Excipients, 5th Edition, R.C. Rowe , P.J. Sheskey, and
S.C. Owen, editors, Pharmaceutical Press, 2005, Hardback, 928, 0853696187.
[0023] For the terms "for example" and "such as" and grammatical equivalences thereof, the
phrase "and without limitation" is understood to follow unless explicitly stated otherwise.
[0024] The term "halogen" or "halo" means F, Cl, Br or I.
[0025] The term "patient" means subjects including animals, such as dogs, cats, cows, horses,
sheep and humans. Particular patients are mammals. The term patient includes males
and females.
[0026] The term "patient in need" means a patient having, or at risk of having, one or more
diseases or conditions where the Mcl-1 protein is involved, such as cancers. Identifying
a patient in need can be in the judgment of a subject or a health care professional
and can be subjective (e.g., opinion) or objective (e.g., measurable by a test or
diagnostic method).
[0027] The phrases "parenteral administration" and "administered parenterally" as used herein
means modes of administration other than enteral and topical administration, usually
by injection, and includes, without limitation, intravenous, intramuscular, intraarterial,
intrathecal, intracapsular, intraorbital, intracardiac, intradermal, intraperitoneal,
transtracheal, subcutaneous, subcuticular, intraarticular, subcapsular, subarachnoid,
intraspinal and intrastemal injection, and infusion.
[0028] Compositions suitable for parenteral injection may comprise physiologically acceptable
sterile aqueous or nonaqueous solutions, dispersions, suspensions, or emulsions, and
sterile powders for reconstitution into sterile injectable solutions or dispersions.
Examples of suitable aqueous and nonaqueous carriers, diluents, solvents, or vehicles
include water, ethanol, polyols (propylene glycol, polyethylene glycol, glycerol,
and the like), suitable mixtures thereof, vegetable oils (such as olive oil) and injectable
organic esters such as ethyl oleate. Proper fluidity can be maintained, for example,
by the use of a coating such as lecithin, by the maintenance of the required particle
size in the case of dispersions, and by the use of surfactants.
[0029] The term "pharmaceutically acceptable" is employed herein to refer to those ligands,
materials, compositions, and/or dosage forms which are, within the scope of sound
medical judgment, suitable for administration to a patient, commensurate with a reasonable
benefit/risk ratio.
[0030] The phrase "pharmaceutically acceptable carrier" as used herein means a pharmaceutically
acceptable material, composition, or vehicle, such as a liquid or solid filler, diluent,
excipient, solvent or encapsulating material. As used herein the language "pharmaceutically
acceptable carrier" includes buffer, sterile water for injection, solvents, dispersion
media, coatings, antibacterial and antifungal agents, isotonic and absorption delaying
agents, and the like, compatible with pharmaceutical administration. Each carrier
must be "acceptable" in the sense of being compatible with the other ingredients of
the formulation and not injurious to the patient. Some examples of materials which
can serve as pharmaceutically acceptable carriers include: (1) sugars, such as lactose,
glucose, and sucrose; (2) starches, such as corn starch, potato starch, and substituted
or unsubstituted β-cyclodextrin; (3) cellulose, and its derivatives, such as sodium
carboxymethyl cellulose, ethyl cellulose, and cellulose acetate; (4) powdered tragacanth;
(5) malt; (6) gelatin; (7) talc; (8) excipients, such as cocoa butter and suppository
waxes; (9) oils, such as peanut oil, cottonseed oil, safflower oil, sesame oil, olive
oil, corn oil, and soybean oil; (10) glycols, such as propylene glycol; (11) polyols,
such as glycerin, sorbitol, mannitol, and polyethylene glycol; (12) esters, such as
ethyl oleate and ethyl laurate; (13) agar; (14) buffering agents, such as magnesium
hydroxide and aluminum hydroxide; (15) alginic acid; (16) pyrogen-free water; (17)
isotonic saline; (18) Ringer's solution; (19) ethyl alcohol; (20) phosphate buffer
solutions; and (21) other non-toxic compatible substances employed in pharmaceutical
formulations. In certain Claims, pharmaceutical compositions provided herein are non-pyrogenic,
i.e., do not induce significant temperature elevations when administered to a patient.
[0031] The term "pharmaceutically acceptable salt" refers to the relatively non-toxic, inorganic
and organic acid addition salts of a compound provided herein. These salts can be
prepared
in situ during the final isolation and purification of a compound provided herein, or by
separately reacting the compound in its free base form with a suitable organic or
inorganic acid, and isolating the salt thus formed. Representative salts include the
hydrobromide, hydrochloride, sulfate, bisulfate, phosphate, nitrate, acetate, valerate,
oleate, palmitate, stearate, laurate, benzoate, lactate, phosphate, tosylate, citrate,
maleate, fumarate, succinate, tartrate, naphthylate, mesylate, glucoheptonate, lactobionate,
laurylsulphonate salts, and amino acid salts, and the like. (See, for example,
Berge et al. (1977) "Pharmaceutical Salts", J. Pharm. Sci. 66: 1-19).
[0032] The phrases "systemic administration", "administered systemically", "peripheral administration",
and "administered peripherally" as used herein mean the administration of a ligand,
drug, or other material via route other than directly into the central nervous system,
such that it enters the patient's system and thus, is subject to metabolism and other
like processes, for example, subcutaneous administration.
[0033] The term "therapeutically effective amount" means an amount of a compound that ameliorates,
attenuates or eliminates one or more symptom of a particular disease or condition,
or prevents or delays the onset of one of more symptom of a particular disease or
condition.
[0034] The terms "treating", "treat" or "treatment" and the like include preventative (e.g.,
prophylactic) and palliative treatment.

in conjunction with any of the above embodiments.
[0152] Provided herein are pharmaceutical compositions that include one or more of the compounds
provided herein.
[0153] In some Claims, a compound provided herein may contain one or more acidic functional
groups and, thus, is capable of forming pharmaceutically acceptable salts with pharmaceutically
acceptable bases. The term "pharmaceutically acceptable salts" in these instances
refers to the relatively non-toxic inorganic and organic base addition salts of a
compound provided herein. These salts can likewise be prepared
in situ during the final isolation and purification of the compound, or by separately reacting
the purified compound in its free acid form with a suitable base, such as the hydroxide,
carbonate, or bicarbonate of a pharmaceutically acceptable metal cation, with ammonia,
or with a pharmaceutically acceptable organic primary, secondary, or tertiary amine.
Representative alkali or alkaline earth salts include the lithium, sodium, potassium,
calcium, magnesium, and aluminum salts, and the like. Representative organic amines
useful for the formation of base addition salts include ethylamine, diethylamine,
ethylenediamine, ethanolamine, diethanolamine, piperazine, and the like (see, for
example, Berge et al., supra).
[0154] Wetting agents, emulsifiers, and lubricants, such as sodium lauryl sulfate and magnesium
stearate, as well as coloring agents, release agents, coating agents, sweetening,
flavoring, and perfuming agents, preservatives and antioxida
[0155] Examples of pharmaceutically acceptable antioxidants include: (1) water soluble antioxidants,
such as ascorbic acid, cysteine hydrochloride, sodium bisulfate, sodium metabisulfite,
sodium sulfite, and the like; (2) oil-soluble antioxidants, such as ascorbyl palmitate,
butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT), lecithin, propyl gallate,
alpha-tocopherol, and the like; and (3) metal chelating agents, such as citric acid,
ethylenediamine tetraacetic acid (EDTA), sorbitol, tartaric acid, phosphoric acid,
and the like.
[0156] A pharmaceutical composition may also contain adjuvants such as preservatives, wetting
agents, emulsifying agents, and dispersing agents. Prevention of the action of microorganisms
may be ensured by the inclusion of various antibacterial and antifungal agents, for
example, paraben, chlorobutanol, phenol sorbic acid, and the like. It may also be
desirable to include tonicityadjusting agents, such as sugars and the like into the
compositions. In addition, prolonged absorption of the injectable pharmaceutical form
may be brought about by the inclusion of agents which delay absorption such as aluminum
monostearate and gelatin.
[0157] In some cases, in order to prolong the effect of one or more compounds provided herein,
it is desirable to slow the absorption of the compound from subcutaneous or intramuscular
injection. For example, delayed absorption of a parenterally administered compound
can be accomplished by dissolving or suspending the compound in an oil vehicle.
[0158] The compounds of the present invention are administered to a patient in a therapeutically
effective amount. The compounds can be administered alone or as part of a pharmaceutically
acceptable composition or formulation. In addition, the compounds or compositions
can be administered all at once, as for example, by a bolus injection, multiple times,
such as by a series of tablets, or delivered substantially uniformly over a period
of time, as for example, using transdermal delivery. The dose of the compound or composition
can be varied over time. All combinations, delivery methods and administration sequences
are contemplated.
[0159] The compounds of the present invention and in some Claims, other additional pharmaceutically
active compounds, can be administered to a patient either orally, rectally, parenterally,
(for example, intravenously, intramuscularly, or subcutaneously) intracisternally,
intravaginally, intraperitoneally, intravesically, locally (for example, powders,
ointments or drops), or as a buccal or nasal spray. All methods that are used by those
skilled in the art to administer a pharmaceutically active agent are contemplated.
[0160] Compositions prepared as described herein can be administered in various forms, depending
on the disorder to be treated and the age, condition, and body weight of the patient,
as is well known in the art. For example, where the compositions are to be administered
orally, they may be formulated as tablets, capsules, granules, powders, or syrups;
or for parenteral administration, they may be formulated as injections (intravenous,
intramuscular, or subcutaneous), drop infusion preparations, or suppositories. For
application by the ophthalmic mucous membrane route, they may be formulated as eye
drops or eye ointments. These formulations can be prepared by conventional means in
conjunction with the methods described herein, and, if desired, the active ingredient
may be mixed with any conventional additive or excipient, such as a binder, a disintegrating
agent, a lubricant, a corrigent, a solubilizing agent, a suspension aid, an emulsifying
agent, or a coating agent.
[0161] Formulations suitable for oral administration may be in the form of capsules (e.g.,
gelatin capsules), cachets, pills, tablets, lozenges (using a flavored basis, usually
sucrose and acacia or tragacanth), powders, troches, granules, or as a solution or
a suspension in an aqueous or non-aqueous liquid, or as an oil-inwater or water-in-oil
liquid emulsion, or as an elixir or syrup, or as pastilles (using an inert matrix,
such as gelatin and glycerin, or sucrose and acacia) and/or as mouthwashes, and the
like, each containing a predetermined amount of a compound provided herein as an active
ingredient. A composition may also be administered as a bolus, electuary, or paste.
Oral compositions generally include an inert diluent or an edible carrier.
[0162] Pharmaceutically compatible binding agents, and/or adjuvant materials can be included
as part of an oral composition. In solid dosage forms for oral administration (capsules,
tablets, pills, dragees, powders, granules, and the like), the active ingredient can
be mixed with one or more pharmaceutically acceptable carriers, such as sodium citrate
or dicalcium phosphate, and/or any of the following: (1) fillers or extenders, such
as starches, cyclodextrins, lactose, sucrose, saccharin, glucose, mannitol, and/or
silicic acid; (2) binders, such as, for example, carboxymethylcellulose, microcrystalline
cellulose, gum tragacanth, alginates, gelatin, polyvinyl pyrrolidone, sucrose, and/or
acacia; (3) humectants, such as glycerol; (4) disintegrating agents, such as agar-agar,
calcium carbonate, potato, corn, or tapioca starch, alginic acid, Primogel, certain
silicates, and sodium carbonate; (5) solution retarding agents, such as paraffin;
(6) absorption accelerators, such as quaternary ammonium compounds; (7) wetting agents,
such as, for example, acetyl alcohol and glycerol monostearate; (8) absorbents, such
as kaolin and bentonite clay; (9) lubricants, such a talc, calcium stearate, magnesium
stearate, Sterotes, solid polyethylene glycols, sodium lauryl sulfate, and mixtures
thereof; (10) a glidant, such as colloidal silicon dioxide; (11) coloring agents;
and (12) a flavoring agent such as peppermint, methyl salicylate, or orange flavoring.
In the case of capsules, tablets, and pills, the pharmaceutical compositions may also
comprise buffering agents. Solid compositions of a similar type may also be employed
as fillers in soft and hard-filled gelatin capsules using such excipients as lactose
or milk sugars, as well as high molecular weight polyethylene glycols, and the like.
[0163] A tablet may be made by compression or molding, optionally with one or more accessory
ingredients. Compressed tablets may be prepared using binder (for example, gelatin
or hydroxypropylmethyl cellulose), lubricant, inert diluent, preservative, disintegrant
(for example, sodium starch glycolate or cross-linked sodium carboxymethyl cellulose),
surface-active or dispersing agent. Molded tablets may be made by molding in a suitable
machine a mixture of a powdered compound moistened with an inert liquid diluent.
[0164] Tablets, and other solid dosage forms, such as dragees, capsules, pills, and granules,
may optionally be scored or prepared with coatings and shells, such as enteric coatings
and other coatings well known in the pharmaceutical-formulating art. They may also
be formulated so as to provide slow or controlled release of the active ingredient
therein using, for example, hydroxypropylmethyl cellulose in varying proportions to
provide the desired release profile, other polymer matrices, liposomes, microspheres,
and/or nanoparticles. They may be sterilized by, for example, filtration through a
bacteria-retaining filter, or by incorporating sterilizing agents in the form of sterile
solid compositions which can be dissolved in sterile water, or some other sterile
injectable medium immediately before use. These compositions may also optionally contain
opacifying agents and may be of a composition that they release the active ingredient(s)
only, or preferentially, in a certain portion of the gastrointestinal tract, optionally,
in a delayed manner. Examples of embedding compositions which can be used include
polymeric substances and waxes. The active ingredient can also be in micro-encapsulated
form, if appropriate, with one or more of the above-described excipients.
[0165] Liquid dosage forms for oral administration include pharmaceutically acceptable emulsions,
microemulsions, solutions, suspensions, syrups, and elixirs. In addition to the active
ingredient, the liquid dosage forms may contain inert diluents commonly used in the
art, such as, for example, water or other solvents, solubilizing agents, and emulsifiers
such as ethyl alcohol, isopropyl alcohol, ethyl carbonate, ethyl acetate, benzyl alcohol,
benzyl benzoate, propylene glycol, 1,3-butylene glycol, oils (in particular, cottonseed,
groundnut, corn, germ, olive, castor, and sesame oils), glycerol, tetrahydrofuryl
alcohol, polyethylene glycols, and fatty acid esters of sorbitan, and mixtures thereof.
[0166] Besides inert diluents, the oral compositions can also include adjuvants such as
wetting agents, emulsifying and suspending agents, sweetening, flavoring, coloring,
perfuming, and preservative agents.
[0167] Suspensions, in addition to the active compound(s) may contain suspending agents
as, for example, ethoxylated isostearyl alcohols, polyoxyethylene sorbitol and sorbitan
esters, microcrystalline cellulose, aluminum metahydroxide, bentonite, agar-agar and
tragacanth, and mixtures thereof.
[0168] Pharmaceutical compositions suitable for parenteral administration can include one
or more compounds provided herein in combination with one or more pharmaceutically
acceptable sterile aqueous or nonaqueous solutions, dispersions, suspensions or emulsions,
or sterile powders which may be reconstituted into sterile injectable solutions or
dispersions just prior to use, which may contain antioxidants, buffers, bacteriostats,
solutes which render the formulation isotonic with the blood of the intended recipient
or suspending or thickening agents.
[0169] In one Claim, the IV formulation consists of a composition containing hydroxypropyl
beta cyclodextrin within a pH range between 8-10 as a buffered or unbuffered solution.
The IV formulation can be formulated as a sterile solution ready for injection, a
sterile solution ready for dilution into an IV admixture or a sterile solid for reconstituion.
The API in the IV formulation may exist as a free acid/base or an in situ salt.
[0170] Examples of suitable aqueous and nonaqueous carriers which may be employed in the
pharmaceutical compositions provided herein include water for injection (e.g., sterile
water for injection), bacteriostatic water, ethanol, polyols (such as glycerol, propylene
glycol, polyethylene glycol such as liquid polyethylene glycol, and the like), sterile
buffer (such as citrate buffer), and suitable mixtures thereof, vegetable oils, such
as olive oil, injectable organic esters, such as ethyl oleate, and Cremophor EL
™ (BASF, Parsippany, NJ). In all cases, the composition must be sterile and should
be fluid to the extent that easy syringability exists. Proper fluidity can be maintained,
for example, by the use of coating materials, such as lecithin, by the maintenance
of the required particle size in the case of dispersions, and by the use of surfactants.
[0171] The composition should be stable under the conditions of manufacture and storage
and must be preserved against the contaminating action of microorganisms such as bacteria
and fungi. Prevention of the action of microorganisms can be achieved by various antibacterial
and antifungal agents, for example, parabens, chlorobutanol, phenol, ascorbic acid,
thimerosal, and the like. In many cases, it will be preferable to include isotonic
agents, for example, sugars, polyalcohols such as mannitol, sorbitol, and sodium chloride
in the composition. Prolonged absorption of the injectable compositions can be brought
about by including in the composition an agent that delays absorption, for example,
aluminum monostearate and gelatin.
[0172] Sterile injectable solutions can be prepared by incorporating the active compound
in the required amount in an appropriate solvent with one or a combination of ingredients
enumerated above, as required, followed by filtered sterilization. Generally, dispersions
are prepared by incorporating the active compound into a sterile vehicle, which contains
a basic dispersion medium and the required other ingredients from those enumerated
above. In the case of sterile powders for the preparation of sterile injectable solutions,
the methods of preparation are freeze-drying (lyophilization), which yields a powder
of the active ingredient plus any additional desired ingredient from a previously
sterile-filtered solution thereof.
[0173] Injectable depot forms can be made by forming microencapsule or nanoencapsule matrices
of a compound provided herein in biodegradable polymers such as polylactide-polyglycolide.
Depending on the ratio of drug to polymer, and the nature of the particular polymer
employed, the rate of drug release can be controlled. Examples of other biodegradable
polymers include poly(orthoesters) and poly(anhydrides). Depot injectable formulations
are also prepared by entrapping the drug in liposomes, microemulsions or nanoemulsions,
which are compatible with body tissue.
[0174] For administration by inhalation, the compounds can be delivered in the form of an
aerosol spray from a pressured container or dispenser that contains a suitable propellant
(e.g., a gas such as carbon dioxide) or a nebulizer. Such methods include those described
in
U.S. Patent No. 6,468,798. Additionally, intranasal delivery can be accomplished, as described in, inter alia,
Hamajima et al., Clin. Immunol. Immunopathol., 88(2), 205-10 (1998). Liposomes (e.g., as described in
U.S. Patent No. 6,472,375, microencapsulation and nanoencapsulation can also be used. Biodegradable targetable
microparticle delivery systems or biodegradable targetable nanoparticle delivery systems
can also be used (e.g., as described in
U.S. Patent No. 6,471,996.
[0175] Systemic administration of a therapeutic compound as described herein can also be
by transmucosal or transdermal means. Dosage forms for the topical or transdermal
administration of a compound provided herein include powders, sprays, ointments, pastes,
creams, lotions, gels, solutions, patches, and inhalants. The active component may
be mixed under sterile conditions with a pharmaceutically acceptable carrier, and
with any preservatives, buffers, or propellants which may be required. For transmucosal
or transdermal administration, penetrants appropriate to the barrier to be permeated
are used in the formulation. Such penetrants are generally known in the art, and include,
for example, for transmucosal administration, detergents, bile salts, and fusidic
acid derivatives. Transmucosal administration can be accomplished through the use
of nasal sprays or suppositories. For transdermal administration, the active compounds
are formulated into ointments, salves, gels, or creams as generally known in the art.
[0176] The ointments, pastes, creams, and gels may contain, in addition to one or more compounds
provided herein, excipients, such as animal and vegetable fats, oils, waxes, paraffins,
starch, tragacanth, cellulose derivatives, polyethylene glycols, silicones, bentonites,
silicic acid, talc, and zinc oxide, or mixtures thereof.
[0177] Powders and sprays can contain, in addition to a compound provided herein, excipients
such as lactose, talc, silicic acid, aluminum hydroxide, calcium silicates, and polyamide
powder, or mixtures of these substances. Sprays can additionally contain customary
propellants, such as chlorofluorohydrocarbons and volatile unsubstituted hydrocarbons,
such as butane and propane.
[0178] A compound provided herein can be administered by aerosol. This is accomplished by
preparing an aqueous aerosol, liposomal preparation, or solid particles containing
a compound or composition provided herein. A nonaqueous (e.g., fluorocarbon propellant)
suspension could be used. In some Claims, sonic nebulizers are used because they minimize
exposing the agent to shear, which can result in degradation of the compound.
[0179] Ordinarily, an aqueous aerosol can be made by formulating an aqueous solution or
suspension of the agent together with conventional pharmaceutically acceptable carriers
and stabilizers. The carriers and stabilizers vary with the requirements of the particular
composition, but typically include nonionic surfactants (TWEEN
®(polysorbates), PLURONIC
® (poloxamers), sorbitan esters, lecithin, CREMOPHOR
®(polyethoxylates)), pharmaceutically acceptable cosolvents such as polyethylene glycol,
innocuous proteins like serum albumin, sorbitan esters, oleic acid, lecithin, amino
acids such as glycine, buffers, salts, sugars, or sugar alcohols. Aerosols generally
are prepared from isotonic solutions.
[0180] Transdermal patches have the added advantage of providing controlled delivery of
a compound provided herein to the body. Such dosage forms can be made by dissolving
or dispersing the agent in the proper medium. Absorption enhancers can also be used
to increase the flux of the compound across the skin. The rate of such flux can be
controlled by either providing a rate controlling membrane or dispersing the compound
in a polymer matrix or gel.
[0181] The pharmaceutical compositions can also be prepared in the form of suppositories
or retention enemas for rectal and/or vaginal delivery. Formulations presented as
a suppository can be prepared by mixing one or more compounds provided herein with
one or more suitable nonirritating excipients or carriers comprising, for example,
cocoa butter, glycerides, polyethylene glycol, a suppository wax or a salicylate,
which is solid at room temperature, but liquid at body temperature and, therefore,
will melt in the rectum or vaginal cavity and release the active agent. Formulations
which are suitable for vaginal administration also include pessaries, tampons, creams,
gels, pastes, foams, or spray formulations containing such carriers as are known in
the art to be appropriate.
[0182] In one claim, the therapeutic compounds are prepared with carriers that will protect
the therapeutic compounds against rapid elimination from the body, such as a controlled
release formulation, including implants and microencapsulated delivery systems. Biodegradable,
biocompatible polymers can be used, such as ethylene vinyl acetate, polyanhydrides,
polyglycolic acid, collagen, polyorthoesters, and polylactic acid. Such formulations
can be prepared using standard techniques, or obtained commercially (e.g., from Alza
Corporation and Nova Pharmaceuticals, Inc). Liposomal suspensions (including liposomes
targeted to selected cells with monoclonal antibodies to cellular antigens) can also
be used as pharmaceutically acceptable carriers. These can be prepared according to
methods known to those skilled in the art, for example, as described in
U.S. Patent No. 4,522,811.
[0183] The compounds of the present invention are used for the treatment of diseases, disorders
or symptoms mediated by Mcl-1 inhibition. Examples of diseases, disorders or symptoms
mediated by Mcl-1 inhibition include, but are not limited to, cancers. Non-limiting
examples of cancers include breast cancer, colorectal cancer, skin cancer, melanoma,
ovarian cancer, kidney cancer, lung cancer, non-small cell lung cancer, lymphoma,
non-Hodgkin's lymphoma, myeloma, multiple myeloma, leukemia, and acute myelogenous
leukemia.
[0184] The cancers can include carcinomas (originating in the outer layer of cells of the
skin and internal membranes, e.g., breasts, kidneys, lungs, skin); sarcomas (arising
from connective tissue such as bone, muscle, cartilage, and blood vessels), and hematologic
malignancies (e.g., lymphomas and leukemias, which arise in the blood or blood-forming
organs such as the spleen, lymph nodes, and bone marrow). Cancer cells can include,
for example, tumor cells, neoplastic cells, malignant cells, metastatic cells, and
hyperplastic cells.
[0185] In an Claim, the disease, disorder or symptom is a hyperproliferative disorder, e.g.,
a lymphoma, leukemia, carcinoma (e.g., renal, breast, lung, skin), multiple myeloma,
or a sarcoma. In one Claim, the leukemia is acute myeloid leukemia. In one Claim,
the hyperproliferative disorder is a relapsed or refractory cancer.
[0186] Actual dosage levels of the active ingredients in the pharmaceutical compositions
provided herein may be varied so as to obtain an amount of the active ingredient which
is effective to achieve the desired therapeutic response for a particular patient,
composition, and mode of administration, without being toxic to the patient.
[0187] The specific dosage and dosage range depends on a number of factors, including the
requirements of the patient, the severity of the condition or disease being treated,
the pharmacokinetic characteristics of the compound(s) employed, and the route of
administration. In some Claims, the compositions provided herein can be provided in
an aqueous solution containing about 0.1-10% w/v of a compound disclosed herein, among
other substances, for parenteral administration. Typical dose ranges can include from
about 0.01 to about 50 mg/kg of body weight per day, given in 1-4 divided doses. Each
divided dose may contain the same or different compounds. The dosage will be a therapeutically
effective amount depending on several factors including the overall health of a patient,
and the formulation and route of administration of the selected compound(s).
[0188] Dosage forms or compositions containing a compound as described herein in the range
of 0.005% to 100% with the balance made up from non-toxic carrier may be prepared.
Methods for preparation of these compositions are known to those skilled in the art.
The contemplated compositions may contain about 0.001%-100% active ingredient, in
one Claim from about 0.1 to about 95%, in another Claim from about 75 to about 85%.
Although the dosage will vary depending on the symptoms, age and body weight of the
patient, the nature and severity of the disorder to be treated or prevented, the route
of administration and the form of the drug, in general, a daily dosage of from about
0.01 to about 3,000 mg of the compound is recommended for an adult human patient,
and this may be administered in a single dose or in divided doses. The amount of active
ingredient which can be combined with a carrier material to produce a single dosage
form will generally be that amount of the compound which produces a therapeutic effect.
[0189] The pharmaceutical composition may be administered at once, or may be divided into
a number of smaller doses to be administered at intervals of time. It is understood
that the precise dosage and duration of treatment is a function of the disease being
treated and may be determined empirically using known testing protocols or by extrapolation
from in vivo or in vitro test data. It is to be noted that concentrations and dosage
values may also vary with the severity of the condition to be alleviated. It is to
be further understood that for any particular patient, specific dosage regimens should
be adjusted over time according to the individual need and the professional judgment
of the person administering or supervising the administration of the compositions,
and that the concentration ranges set forth herein are exemplary only and are not
intended to limit the scope or practice of the Claimed compositions.
[0190] The precise time of administration and/or amount of the composition that will yield
the most effective results in terms of efficacy of treatment in a given patient will
depend upon the activity, pharmacokinetics, and bioavailability of a particular compound,
physiological condition of the patient (including age, sex, disease type and stage,
general physical condition, responsiveness to a given dosage, and type of medication),
route of administration, etc. However, the above guidelines can be used as the basis
for fine-tuning the treatment, e.g., determining the optimum time and/or amount of
administration, which will require no more than routine experimentation consisting
of monitoring the patient and adjusting the dosage and/or timing
[0191] The compounds of the present invention can be administered alone, in combination
with other compounds of the present invention, or with other pharmaceutically active
compounds or agents. The other pharmaceutically active compounds/agents can be intended
to treat the same disease or condition as the compounds of the present invention or
a different disease or condition. If the patient is to receive or is receiving multiple
pharmaceutically active compounds or agents, the compounds can be administered simultaneously,
or sequentially.
[0192] The compounds of the present invention, or pharmaceutically acceptable salts thereof,
may be used in combination with one or more additional pharmaceutically active compounds/agents.
[0193] One or more additional pharmaceutically active compounds or agents may be administered
separately, as part of a multiple dose regimen, from the compound of Formula I' (e.g.,
sequentially, e.g., on different overlapping schedules with the administration of
one or more compounds of Formula I' (including any subgenera or specific compounds
thereof). In other Claims, the one or more additional compounds/agents may be part
of a single dosage form, mixed together with the compound of Formula I' in a single
composition. In still another Claim, the one or more additional compounds/agents can
be given as a separate dose that is administered at about the same time that one or
more compounds of Formula I' are administered (e.g., simultaneously with the administration
of one or more compounds of Formula I' (including any subgenera or specific compounds
thereof). Both the compound of Formula I' and the one or more additional compounds/agents
can be present at dosage levels of between about 1 to 100%, and more preferably between
about 5 to 95% of the dosage normally administered in a monotherapy regimen.
[0194] In a particular claim, the additional pharmaceutically active compound/agent is a
compound or agent that can be used to treat a cancer. For example, the additional
pharmaceutically active compound/agent can be selected from antineoplastic agents,
anti-angiogenic agents, chemotherapeutic agents, and peptidal cancer therapy agents.
In another Claim, the antineoplastic agents are selected from antibiotic-type agents,
alkylating agents, antimetabolite agents, hormonal agents, immunological agents, interferon-type
agents, kinase inhibitors, proteasome inhibitors, and combinations thereof. It is
noted that the additional pharmaceutically active compound/agent may be a traditional
small organic chemical molecule or can be a macromolecule such as a protein, antibody,
peptibody, DNA, RNA or a fragment of such macromolecules.

6)alkyl)
2 or glycosyl (the radical resulting from the removal of a hydroxyl group of the hemiacetal
form of a carbohydrate).
[0205] The compounds of the present invention may contain asymmetric or chiral centers,
and therefore, exist in different stereoisomeric forms. It is contemplated that all
stereoisomeric forms of the compounds as well as mixtures thereof, including racemic
mixtures, form part of the present invention. In addition, the present invention contemplates
all geometric and positional isomers. For example, if the compound contains a double
bond, both the cis and trans forms (designated as Z and E, respectively), as well
as mixtures, are contemplated.
[0206] Mixture of stereoisomers, such as diastereomeric mixtures, can be separated into
their individual stereochemical components on the basis of their physical chemical
differences by known methods such as chromatography and/or fractional crystallization.
Enantiomers can also be separated by converting the enantiomeric mixture into a diasteromeric
mixture by reaction with an appropriate optically active compound (e.g., an alcohol),
separating the diastereomers and converting (e.g., hydrolyzing) the individual diastereomers
to the corresponding pure enantiomers.
[0207] The compounds of the present invention may exist in unsolvated as well as solvated
forms with pharmaceutically acceptable solvents such as water (hydrate), ethanol,
and the like. The present invention contemplates and encompasses both the solvated
and unsolvated forms.
[0208] It is also possible that compounds of the present invention may exist in different
tautomeric forms. All tautomers of compounds of the present invention are contemplated.
Those skilled in the art will recognize that the compound names and structures contained
herein may be based on a particular tautomer of a compound. While the name or structure
for only a particular tautomer may be used, it is intended that all tautomers are
encompassed by the present invention, unless stated otherwise.
[0209] It is also intended that the present invention encompass compounds that are synthesized
in vitro using laboratory techniques, such as those well known to synthetic chemists;
or synthesized using in vivo techniques, such as through metabolism, fermentation,
digestion, and the like. It is also contemplated that the compounds of the present
invention may be synthesized using a combination of in vitro and in vivo techniques.
[0210] The compounds of the present invention may exist in various solid states including
crystalline states and as an amorphous state. The different crystalline states, also
called polymorphs, and the amorphous states of the present compounds are contemplated
as part of this invention.

[0266]

Step 1: (3R,4S)-1-methoxy-N,N-bis(4-methoxybenzyl)-4-methylhept-6-ene-3-sulfonamide
[0267] A dry 2 L three neck flask with a thermo couple and magnetic stir bar under nitrogen
was charged with (S)-N,N-bis(4-methoxybenzyl)-2-methylpent-4-ene-1-sulfonamide (54
g, 134 mmol) and 300 mL of dry toluene. Cooled solution to -76 °C internal temperature
(acetone/dry ice bath). Added n-butyllithium solution (1.6 M in hexanes, 100 mL, 161
mmol) slowly via cannula under a positive pressure of nitrogen. The mixture was stired
at -78 °C for 1 hour. Then 2-bromoethyl methyl ether (18.88 mL, 201 mmol) was slowly
via syringe. After the addition, the -78 °C bath was replaced with an ice water bath.
After a total of 105 minutes reaction time, the reaction was quenched with saturated
ammonium chloride at 0 °C. The mixture was diluted with water and EtOAc and warmed
to room temperature with stirring. The layers were separated and extracted with additional
EtOAc. The combined organic layers were washed with water and brine, dried over sodium
sulfate, filtered, and concentrated in vacuo. The crude products were further separated
to give 20.4 g of (3R,4S)-1-methoxy-N,N-bis(4-methoxybenzyl)-4-methylhept-6-ene-3-sulfonamide

Step 2: (3R,4S)-1-methoxy-4-methylhept-6-ene-3-sulfonamide
[0268] At 0 °C, trifluoroacetic acid (164 mL, 2210 mmol) was added dropwise via addition
funnel to a solution of (3R,4S)-1-methoxy-N,N-bis(4-methoxybenzyl)-4-methylhept-6-ene-3-sulfonamide
(20.4 g, 44.2 mmol) and anisole (48.0 mL, 442 mmol) in DCM (221 mL). The solution
was allowed to come to room temperature and stirred overnight. The reaction was concentrated
in vacuo. The remaining material was partitioned between DCM and saturated aqueous
sodium bicarbonate. The layers were separated and the aqueous layer was extracted
with DCM. The combined organic extracts were washed with saturated aqueous sodium
chloride and dried over sodium sulfate. The solution was filtered and concentrated
in vacuo to give the crude material. Purification by flash column chromatography on
silica gel (eluted with 0% to 100% EtOAc in heptane) gave (3R,4S)-1-methoxy-4-methylhept-6-ene-3-sulfonamide

[0269] To a nitrogen inerted 3-neck 1 L flask equipped with a thermometer and a magnetic
stir bar at room temperature was added 4-(dimethylamino) pyridine (0.821 g, 6.72 mmol),
2-methyltetrahydrofuran (80 mL), triethylamine (7.02 mL, 50.4 mmol), acetic anhydride
(4.76 mL, 50.4 mmol), and a solution of (S)-6'-chloro-5-(((1R,2R)-2-((S)-1-hydroxyallyl)cyclobutyl)methyl)-3',4,4',5-tetrahydro-2H,2'H-spiro[benzo[b][1,4]oxazepine-3,1'-naphthalene]-7-carboxylic
acid (15.72 g, 33.6 mmol) in 2-methyltetrahydrofuran (80 mL) was added via cannula
over 20 min (internal temperature increased from 20 °C to 25 °C during the addition).
The reaction mixture was stirred at room temperature for 1.5 h. Water (40 mL) was
added (internal temperature increased from 23 °C to 26 °C) followed by 1 M Na
2HPO
4 (60 mL). Sodium hydroxide (1 M, 20 mL, 220 mmol) was added until the pH reached 9.
The mixture was stirred at room temperature for 19 h and the pH was adjusted to 3
with 2 M HCl (80 mL). The mixture was diluted with PhMe (150 mL) and transferred to
a separatory funnel. The aqueous layer was discarded and the organic phase was washed
with water (75 mL), 20% brine (75 mL), and concentrated under reduced pressure. The
concentrate was diluted with PhMe (100 mL) and the PhMe was removed under reduced
pressure. This was repeated three times to give (S)-5-(((1R,2R)-2-((S)-1-acetoxyallyl)cyclobutyl)methyl)-6'-chloro-3',4,4',

was added followed by slow addition of thionyl chloride (2.74 mL, 37.6 mmol) via syringe.
The reaction was stirred at room temperature for 4 h and additional thionyl chloride
(0.50 mL) was added and the reaction was stirred for 1 h. In a separate flask (3R,4S)-1-methoxy-4-methylhept-6-ene-3-sulfonamide
(9.85 g, 42.5 mmol) and 4-(dimethylamino)pyridine (0.437 g, 3.58 mmol) were combined
and azetroped by concentration in vacuo with PhMe (80 mL) and then taken up in 100
mL of PhMe. The resulting solution was added to the acid chloride solution described
above via cannula. The solution was cooled in an ice bath for 10 min before triethylamine
(17.41 mL, 125 mmol) was added dropwise via addition funnel. After the addition, the
reaction was warmed to room temperature and stirred overnight. The reaction was quenched
with saturated ammonium chloride. To the mixture was added 0.1 M aqueous HCl and then
the mixture was extracted with EtOAc (3x). The combined organic layers were washed
with brine, dried with sodium sulfate, filtered, and concentrate in vacuo. Purification

13',13'-dioxide (50 mg, 0.071 mmol) in DCE (2 mL) and N,N-diisopropylethylamine (0.1
mL, 0.574 mmol). After 1.5 h, the solution was treated with sodium triacetoxyborohydride
(6 mg). After a further 3 h, the reaction was treated with more sodium triacetoxyborohydride
(7 mg). After a further 16 h, the reaction was again treated with sodium triacetoxy
borohydride (6 mg). The reaction was monitored by LC-MS and sodium triacetoxyborohydride
added in 5-10 mg portions until reaction was judged complete. After a further 24 h,
the reaction was diluted with DCE (3 mL). After 4 d, the reaction was treated with
acetic acid (12 µL, 0.208 mmol). After a further 24 h, more acetic acid (18 µL) was
added. After a further 24 h, the reaction was treated with another 30 mg of amine.
After a further 96 h, the reaction was treated with larger portions of sodium triacetoxyborohydride
to drive reaction to desired product or the alcohol resulting from reduced aldehyde.

GENERAL SYNTHESIS OF INTERMEDIATES
N-Methyl-2-morpholinoethanamine
[0488]

Step 1: tert-butyl (2-morpholinoethyl)carbamate
[0489] A 2-dram vial was charged with di-t-butyldicarbonate (0.459 mL, 2.000 mmol), a magnetic
stir bar, and indium (III) chloride (4.42 mg, 0.020 mmol). 4-(2-Aminoethyl)morpholine
(0.262 mL, 2 mmol) was then added to the stirring solution. After 1 min, the solution
was diluted with EtOAc (2 mL). Water (3 mL) was added and the layers were partitioned.
The organic layer was washed with water (2 × 5 mL), dried over MgSO
4, filtered, and concentrated to afford tert-butyl (2-morpholinoethyl)carbamate as
a clear oil. The material was carried forward without further purification.
Step 2: N-methyl-2-morpholinoethanamine
[0490] A 125 mL three-neck flask with stir bar was heated with a heat gun under vacuum.
Under a positive pressure of nitrogen, a reflux condenser was attached to the middle
neck. The flask was charged with tetrahydrofuran (25.00 mL) and lithium aluminium
hydride (2 M solution in THF, 0.84 mL, 20 mmol), tert-butyl (2-morpholinoethyl)carbamate

while maintaining the temperature at -20°C. The filter cake was washed with two portions
of cold (<-10°C) THF (2 × 14.2 g, 2V) rinsed through the reaction vessel. The filter
cake (4-methylmorpholine·HCl) was transferred to a labeled container. The mother liquor
and washes were concentrated to a minimum volume and distillative solvent swap by

conversion. The batch was quenched by the addition of H
2O (14 L, 5 vol) over ~20 min. maintaining the batch temperature below 15°C and then
toluene (16.8 L, 6 vol) was added. After partition, the organic layer was treated
with H
2O (14 L, 5 vol) and toluene (16.8 L, 6 vol). The top organic layer was washed with
2 N HCl twice (14 L each, 5 vol) and brine (14 L, 5 vol). The organic layer was drained
to a clean container, assayed by HPLC and then transferred back to the clean 60L reactor
through an inline filter. The batch was concentrated to a minimal volume and solvent
switched to MeOH until the batch volume was 28 L (10 vol) and MeOH/toluene ratio was
3:1 (v/v) as measured by QNMR. The batch was then transferred to a 30L jacketed reactor

was seeded with the aldehyde (51 g, 0.02 eq) as a slurry in MeOH (400 mL). After the
slurry was aged for 30 min at 30°C, the batch was solvent switched by distillation
with MeOH until the batch volume is 11 L (4 vol) and MeOH/toluene ratio is ≥99:1 (v/v).
The batch was then cooled to 5°C and MeOH/H
2O mixture (3.70 Kg MeOH + 1.34 Kg H
2O) was added over 1.5 h to bring the total solvent volume to approximately 5.5 vol
and final MeOH/H
2O to 90/10 (v/v). The batch was heated to 65°C over 30 min, and cooled to 20°C over

98% conversion. To the batch in the flask was added sat. NH
4Cl solution (10 mL), maintaining the temperature at -20 ± 10°C, followed by addition
of H
2O (20 mL) and MeTHF (34 mL) at -20 ± 20°C. The mixture was warmed to 20°C and agitated
for 13 h. The batch was transferred to a separatory funnel, allowed to settle for
~5 min, and the bottom aqueous layer was removed keeping the rag with the organic
stream. The top organic stream was washed with sat. NH
4Cl solution (10 mL) and H
2O (20 mL) at 20°C. After ~5 min of settling, the aqueous layer was separated. To the
total crude organic stream (KF=14%) was added MSA (4 mL) in a 250mL 3-necked-RBF.
The batch was heated to reflux (65°C) for 25 h and LC assay showed full conversion
(≥97%).
[0607] The batch was cooled to <20°C and K
3PO
4·H
2O (4.5 g) and H
2O (7 mL) were added. The batch was transferred to a separatory funnel and the bottom
aqueous layer was drained to give the aldehyde product crude solution. The combined
organic crude stream was concentrated to minimum volume using a rotary evaporator.
To the batch in a 500mL RBF was charged AcOH (~50 mL, ~50 mL) and distilled using
a rotary evaporator at reduced pressure (30 mbar, external temp ~40°C). The THF level
was measured by QNMR and none was observed. The mixture was transferred to a 250mL
3-necked RBF and AcOH was added to adjust the total volume to ~40 mL, when crystallization
occurred. To the batch was added H
2O (12 mL) over ~ 1 h. After aging for >1 h, LC assay of supernatant concentration
was 9 mg/mL. If concentration is >10 mg/mL then a small portion of H
2O (0.2 vol) can be added; after checking by LC, repeat if necessary. The batch was
filtered, washed with 20% H
2O/AcOH (23 mL) and dried under N
2/vacuum for 3.25 h to give the title compound (8.22 g) as an off-white solid (82%
yield corrected for purity).

[0614] The reaction mixture was filtered through a Celite
® pad (2 inch) using additional THF for rinses, and the filtrate was concentrated under
reduced pressure at 40 °C. To the residue was added IPA (60 mL) and 2-4% aqueous MeOH
(10 mL). The mixture was stirred for 10 min and then it was filtered through a Celite
® pad (2 inch). MeOH was evaporated under reduced pressure at 40 °C and to the concentrated
IPA solution cooled to ambient temperature was added a solution of +CSA (56.0 g) in
IPA (200 mL) dropwise over 2 h. After 10% of the CSA solution has been added, the
mixture was seeded with crystals of the title compound (10 - 15 mg) followed by the

(40 g, 317 mmol) was gradually added over 2 h, maintaining the internal temperature
of the reaction mixture below 50°C. The reaction was stirred overnight at ambient
temperature under argon. After 16 h, the reaction mixture was cooled by an ice bath
to 10°C, and, under a fast stream of argon, a solution of 36 mL H
2O was added drop wise by addition funnel at a rate that maintained the temperature
between 12 - 15°C, approximately 1 mL/min, with vigorous stirring (500 rpm). The mixture
was then vigorously stirred (500 rpm) in the ice-bath for 1 h, then removed from the
bath and stirred to rt for 1 h before cooling again with an ice bath to 5-10°C. To
the mixture was added 36 mL of a 15% NaOH aqueous solution over a period of 45 min,
maintaining the temperature between 10 - 20°C. To the mixture was added 108 mL H
2O drop wise by addition funnel, maintaining the temperature between 10 - 20°C, over
~1 h. Upon completed addition of the H
2O, the flask was removed from the ice bath, equilibrated to rt and left to stir vigorously
under argon overnight. After stirring for 16 h, the mixture was filtered and the filtrate
concentrated under reduced pressure to afford a colorless, slightly opaque oil. The
oil was taken up in Et
2O and stirred over anhydrous MgSO

CIS-1,2-cyclobutanediyldimethanol (1.06 g, 9.15 mmol) and the resulting solution was
heated to 50°C. After stirring overnight, the mixture was assayed by GC and showed
complete conversion. The mixture was then diluted with 15mL of heptane and concentrated
under vacuum to give a clear oil. The oil was dissolved in 15mL heptane and concentrated
back down to an oil (azeotropic removal of Ac
2O) to give the title compound as an oil (1.827g, 88% yield, 88.3% purity by QNMR using

Pseudomonas fluorescens (41.8 g, 1547 mmol) was then added in one charge (pH ~ 8.12) and the mixture was
vigorously stirred at ambient temperature for ~5 min. (1R,2S)-cyclobutane-1,2-diylbis(methylene)
diacetate (348 g, 1547 mmol) was added in one charge and the resulting mixture was
stirred vigorously at ambient temperature monitoring internal temperature and pH.
After stirring the mixture overnight (~20.9°C and pH~5.45) an aliquot was collected,
extracted with IPAc, diluted with MeCN and analyzed by GC and the reaction was deemed
complete (1.21% SM leftover, 0.17% of enantiomer, 1.8% of diol). Celite
® (70 g) added to the reaction mixture and the slurry was filtered through a Celite
® pad on a medium porosity glass filter (fast filtration, 15-20 min), rinsing with
2.5 L IPA. The biphasic mixture was transferred into a 12L-extractor and stirred for

addition: the temperature decreased to 15°C). TEMPO (3.97 g, 25.4 mmol) was added
as a solid in one portion resulting in a cloudy orange solution, which became clear
over the course of 20 min. After stirring at 20°C overnight, an aliquot was collected,
diluted with MeOH, and analyzed by GC. An Additional kicker charge of iodobenzene
diacetate and TEMPO can be used to push the reaction to completion if necessary. The
reaction mixture was then cooled to 1.8°C (internal temperature, ice/dry ice/ H
2O bath) and DIPEA (194 mL, 1113mol) was added drop-wise via addition funnel over 65
min keeping internal temperature <5°C. The cooling bath was removed and the mixture
was allowed to warm to ambient temperature with stirring. After 48 h an aliquot was
collected, diluted with methanol, and analyzed by GC showing a 12:1 ratio of
trans: cis isomers. The reaction mixture was then cooled to <5°C (ice/ H
2O bath) and H
2O (230 mL) was added over ~ 10 min (internal temperature reached 14°C). The organic

[0718] To a 20L reactor blanketed in argon was charged 14 L of 1,2-DCE. (S)-6'-chloro-5-(((1R,2R)-2-((S)-1-hydroxyallyl)cyclobutyl)methyl)-N-(((2R,3S)-3-methylhex-5-en-2-yl)sulfonyl)-3',4,4',5-tetrahydro-2H,2'H-spiro[benzo[b][1,4]oxazepine-3,1'-naphthalene]-7-carboxamide
(18.75 g, 29.9 mmol) was added as a solution in 400 mL 1,2-DCE followed by a 400 mL
rinse. The reactor was sealed and purged with argon. Hoveyda-Grubbs II (1.873 g, 2.99
mmol) was added as a solution in 150 mL of 1,2-DCE followed by a 50 mL rinse. The
reactor was heated to 60°C over 1 h with an argon sweep of the headspace and held
at temperature for 9 h. The reaction was quenched by the addition of 2-(2-(vinyloxy)ethoxy)ethanol
(1.501 g, 11.36 mmol), cooled to ambient temperature, and concentrated to ∼ 200 mL
volume by rotary evaporation. The reaction was transferred to a 1 L RBF and diluted
to 500 mL volume with 1,2-DCE. The reaction was treated with 52 g of Silicycle Si-Thiol
(SiliCycle Inc., Quebec City, Quebec CANADA Cat# R51030B) with stirring for 9 h at
40°C, filtered and rinsed with 2 x 65 mL DCM. The solution was passed through a Whatman
GF/F filter cup (GE Healthcare Bio-Sciences Pittsburgh, PA, USA) to afford a transparent
yellow solution. The reaction was concentrated to afford a crude product mass of 27.4
g. The residue was slurried in 250 mL IPAc and evaporated to dryness three times.
The reaction was suspended in 270 mL IPAc, heated to dissolution, allowed to cool
to ambient temperature, and stirred for 18. The solids were filtered and washed with
65 mL IPAc. The solid was air-dried for 30 min then placed under high vacuum for 3

BIOLOGICAL ASSAYS
Cell free Mcl-1:Bim affinity assay (Mcl-1 HTRF)
[0725] The inhibition of the Mcl-1/Bim interaction was measured using a timeresolved fluorescence
resonance energy transfer (TR-FRET) assay. The recombinant human Mcl-1 (C-terminally
6xHis tagged Mcl-1 containing residues 171-327) was generated at Amgen Inc (Thousand
Oaks, CA). A biotinylated peptide derived from human Bim (residues 51-76) was purchased
from CPC Scientific (San Jose, CA). The TR-FRET assay was conducted in a 384-well
white OptiPlate
™ (PerkinElmer, Waltham, MA) in a total volume of 40 µL. The reaction mixture contained
0.1 nM Mcl-1(171-327), 0.05 nM biotin-Bim(51-76), 0.05 nM LANCE
® Eu-W1024 Anti-6xHis (PerkinElmer), 0.072 nM Streptavidin-Xlent (Cisbio, Bedford,
MA), and serially diluted test compounds in the binding buffer of 20 mM Hepes, pH
7.5, 150 mMNaCl, 0.016 mM Brij
®35, and 1 mM dithiothreitol. Test compounds were pre-incubated with Mcl-1(171-327)
and biotin-Bim (51-76) for 60 min before addition of the detection mixture (LANCE
®Eu-W1024 Anti-6xHis and Streptavidin-Xlent). The reaction plates were further incubated
overnight and then were read on an Envision
® multimode reader (PerkinElmer). Fluorescence signals were measured at 620 nm (40-nm
bandwidth) and 665 nm (7.5-nm bandwidth) with a 60 µs delay after excitation at 320
nm (75-nm bandwidth). The signal ratio at 665/620 nm corresponded to the Mcl-1/Bim
interaction and was used in all data analyses. The IC
50 values of test compounds were determined from duplicate data by analyzing competition
curves using a four-parameter sigmoidal model in GraphPad Prism (GraphPad Software,
San Diego, CA) or in Genedata Screener
® (Genedata, Basel, Switzerland).
Cell viability assay (OPM-2 10 FBS)
[0726] The human multiple myeloma cell line, OPM-2, was cultured in complete growth medium
containing RPMI 1640 and 10% fetal bovine serum (FBS). Cells were seeded into 384-well
plates at 3000 cells/well density in complete growth medium containing 10% FBS, and
incubated for 16 h with serially diluted test compounds in a 37°C incubator with 5%
CO
2. Cell viability was tested using CellTiter-Glo
® assay (Promega, Madison, WI) according to the manufacturer recommendations. Luminescence
was determined using an EnVision
® Multilabel plate reader 25 min after the addition of detection reagent. IC
50 values were then calculated with Xlfit using a logistical 4-parameter fit model in
GraphPad Prism (GraphPad Software, San Diego, CA) or in Genedata Screener
® (Genedata, Basel, Switzerland).

In-Vivo Data
Tumor Pharmacodynamics (PD)
[0728] Figures 1-7 illustrate the PD results of the cited Examples. The Reference Compound
1, an internal Amgen MCl-1 inhibitor compound made by one of the general schemes outlined
in
U.S. Patent No. 9,562,061 is (1S,3'R,6'R,7'S,8'E,12'R)-6-chloro-12'-ethyl-7'-methoxy-3,4-dihydro-2H,15'H-spiro[naphthalene-1,22'-[20]oxa[13]thia[1,14]diazatetracyclo[14.7.2.0~3,6~.0~19,24~]
pentacosa[8, 16, 18,24]tetraen]-15'-one 13', 13'-dioxide

[0729] Female Athymic nude (Charles River Laboratories, Inc., Hollister CA) mice were inoculated
subcutaneously with 5 x 10
6 OPM-2 Luc cells. When tumors reached 300-500 mm
3 in size, mice were randomized into treatment groups and harvested 6 hours post single
dose of compound at various concentrations. Tumor lysates were analyzed for active
Bak using a sandwich ELISA format (Active Bak MSD plate cat #N45ZA-1; Bak detection
antibody Abcam Cat# Ab53153 and Sulfo-Tagged by MSD) and read on a MSD reader (S16000).
Columns (n=3 per group) represent level of luminescence (cps). Statistical significance
was determined by Oneway ANOVA followed by Dunnett's post hoc compared to the vehicle
control group. Black diamonds represent drug plasma concentration and circles represent
drug concentration in the tumor.
OPM-2 Xenograft
[0730] Examples 8-13 illustrate Xenograft data of various compounds of the present invention.
Female Athymic nude (Charles River Laboratories, Inc., Hollister CA) mice were inoculated
subcutaneously with 5 x 10
6 OPM-2 Luc cells. When average tumor volumes reached approximately 155-183 mm
3, animals were randomized (n=10/group) and dosed once daily by oral gavage (10-12
days) with test compounds at various concentrations unless notes otherwise. Tumor
volume and body weights were recorded twice per week using electronic calipers and
an analytical scale. Statistical analysis was performed using Repeated Measures ANOVA
(RMANOVA) followed by Dunnett's post-hoc analysis.
[0731] The foregoing description is merely illustrative of the invention and is not intended
to limit the invention to the disclosed compounds, compositions and methods. Variations
and changes, which are obvious to one skilled in the art, are intended to be within
the scope and nature of the invention, as defined in the appended Claims.
