2. FIELD OF THE INVENTION
[0002] The present invention relates to aromatic organic compounds which are specific, potent
and safe inhibitors of the Ca
2+-activated potassium channel (Gardos channel) of erythrocytes and/or of mammalian
cell proliferation. The compounds can be used to inhibit mammalian cell proliferation
in situ as a therapeutic approach towards the treatment or prevention of diseases
characterized by abnormal cell proliferation.
3. BACKGROUND OF THE INVENTION
[0003] Cell proliferation is a normal part of mammalian existence, necessary for life itself.
However, cell proliferation is not always desirable, and has recently been shown to
be the root of many life-threatening diseases such as cancer, certain skin disorders,
inflammatory diseases, fibrotic conditions and arteriosclerotic conditions.
[0004] Cell proliferation is critically dependent on the regulated movement of ions across
various cellular compartments, and is associated with the synthesis of DNA. Binding
of specific polypeptide growth factors to specific receptors in growth-arrested cells
triggers an array of early ionic signals that are critical in the cascade of mitogenic
events eventually leading to DNA synthesis (Rozengurt, 1986,
Science 234:
161-164). These include (1) a rapid increase in cystolic Ca
2+, mostly due to rapid release of Ca
2+ from intracellular stores; (2) capacitative Ca
2+ influx in response to opening of ligand-bound and hyperpolarization-sensitive Ca
2+ channels in the plasma membrane that contribute further to increased intracellular
Ca
2+ concentration (Tsien and Tsien.
1990, Annu. Rev. Cell Biol. 6:715-760; Peppelenbosch et al., 1991,
J. Biol, Chem. 266:19938-19944); and (3) activation of Ca
2+-depeadent K
+ channels in the plasma membrane with increased K
+ conductance and membrane hyperpolarisation (Magni et al.,
1991,
J. Biol. Chem. 261:9321-9327). These mitogen induced early ionic changes, considered critical events in the signal
transduction pathways, are powerful therapeutic targets for inhibition of cell proliferation
in normal and malignant cells.
[0005] One therapeutic approach towards the treatment of diseases characterized by unwanted
or abnormal cell proliferation via alteration of the ionic fluxes associated with
early mitogenic signals involves the actrainistration of Clotrimazole. As discussed
above, Clotrimazole has been shown to inhibit the Ca
2+ activated potassium channel of erythrocytes. In addition, Clotrimazole inhibits voltage-
and ligand-stimulated Ca
2+ influx mechanisms in nucleated cells (villalobos
et al., 1992,
FASEB J. 6:2742-2747; Montero et
al:, 1991,
Biochem. J. 277:73-79) and inhibits cell proliferation both
in vitro and
in vivo (Benzaquen
et al., 1995,
Nature Medicine 1:534-540). Recently, Clotrimazole and other imidazole-containing antimycotic agents
capable of inhibiting Ca
2+-activated potassium channels have been shown to be useful in the treatment of arteriosclerosis
(U.S. Patent No. 5,358,959 to Halperin et al.), as well as other disorders characterized
by unwanted or abnormal cell proliferation.
[0006] As can be seen from the above discussion, inhibiting mammalian cell proliferation
via alteration of ionic fluxes associated with early mitogenic signals is a powerful
therapeutic approach towards the treatment and/or prevention of diseases characterized
by unwanted or abnormal cell proliferation. Compounds capable of inhibiting mammalian
cell proliferation are highly desirable, and are therefore also an object of the present
invention.

5. DETAILED DESCRIPTION OF THE INVENTION
[0016] As discussed in the Background section, the modulation of early ionic mitogenic signals
and inhibition of cell proliferation are powerful therapeutic approaches towards the
treatment and/or prevention of disorders characterized by abnormal cell proliferation.
It has been shown that Clotrimazole, in addition to inhibiting the Gardos channel
of erythrocytes, also modulates ionic mitogenic signals and inhibits cell proliferation
both
in vitro and
in vivo.
[0017] For example, Clotrimazole inhibits the rate of cell proliferation of normal and cancer
cell lines in a reversible and dose-dependent manner
in vitro (Benzaquen
et al., 1995
Nature Medicine 1:534-540). Clotrimazole also depletes the intracellular Ca
2+ stores and prevents the rise in cystolic Ca
2+ that normally follows mitogenic stimulation. Moreover, in mice with severe combined
immunodeficiency disease (SCID) and inoculated with MM-RU human melanoma cells, daily
administration of Clotrimazole resulted in a significant reduction in the number of
lung metastases observed (Benzaquen
et al., supra).
[0018] Quite surprisingly, it has now been discovered that the imidazole-like ring moieties
of Clotrimazole and the other above-mentioned antimycotic agents, which are well-recognized
as the essential functionality underlying their antimycotic and other biological activities,
is not the underlying functionality responsible for effecting inhibition of the Gardos
channel or inhibition of mitogen-induced mammalian cell proliferation. Thus, based
in part on this surprising discovery, in one aspect the present invention provides
a new class of organic compounds that are capable of inhibiting mammalian cell proliferation,
particularly mitogen-induced cell proliferation.
[0019] The compounds of the invention are potent, specific inhibitors of mammalian cell
proliferation. Thus, in another aspect, the invention enables inhibiting mammalian
cell proliferation as a therapeutic approach towards the treatment or prevention of
diseases characterized by unwanted or abnormal cell proliferation. In its broadest
sense, this involves an effective amount of at least one pharmacologically active
compound according to the invention to be administered to a mammalian cell in situ.
The compound may act cytostatically, cytotoxically, or by a combination of both mechanisms
to inhibit cell proliferation. Mammalian cells treatable in this manner include vascular
smooth muscle cells, fibroblasts, endothelial cells, various pre-cancer cells and
various cancer cells. In a preferred embodiment, cell proliferation is to be inhibited
in a subject suffering from a disorder that is characterized by unwanted or abnormal
cell proliferation. Such diseases are described more fully below.
[0020] Based in part on the surmised role of mammalian cell proliferation in certain diseases,
the invention enables the treatment or prevention of diseases characterized by abnormal
cell proliferation. This involves, an effective amount of at least one compound according
to the invention, or a pharmaceutical composition thereof, is to be administered to
a patient suffering from a disorder that is characterized by abnormal cell proliferation.
While not intending to be bound by any particular theory, it is believed that administration
of an appropriate amount of a compound according to the invention to a subject inhibits
cell proliferation by altering the ionic fluxes associated with early mitogenic signals.
Such alteration of ionic fluxes is thought to be due to the ability of the compounds
of the invention to inhibit potassium channels of cells, particularly Ca
2+-activated potassium channels. The described method can be used prophylactically to
prevent unwanted or abnormal cell proliferation, or may be used therapeutically to
reduce or arrest proliferation of abnormally proliferating cells. The compound, or
a pharmaceutical formulation thereof, can be applied locally to proliferating cells
to arrest or inhibit proliferation at a desired time, or may be administered to a
subject systemically to arrest or inhibit cell proliferation.
[0021] Diseases which are characterized by abnormal cell proliferation that can be treated
or prevented by means of the present invention include blood vessel proliferative
disorders, fibrotic disorders, and various cancers.
[0022] Blood vessel proliferation disorders refer to angiogenic and vasculogenic disorders
generally resulting in abnormal proliferation of blood vessels. The formation and
spreading of blood vessels, or vasculogenesis and angiogenesis, respectively, play
important roles in a variety of physiological processes such as embryonic development,
corpus luteum formation, wound healing and organ regeneration. They also play a pivotal
role in cancer development. Other examples of blood vessel proliferative disorders
include arthritis, where new capillary blood vessels invade the joint and destroy
cartilage and ocular diseases such as diabetic retinopathy, where new capillaries
in the retina invade the vitreous, bleed and cause blindness and neovascular glaucoma.
[0023] Another example of abnormal neovascularization is that associated with solid tumors.
It is now established that unrestricted growth of tumors is dependent upon angiogenesis
and that induction of angiogenesis by liberation of angiogenic factors can be an important
step in carcinogenesis. For example, basic fibroblast growth factor (bFGF) is liberated
by several cancer cells and plays a crucial role in cancer angiogenesis. The demonstration
that certain animal tumors regress when angiogenesis is inhibited has provided the
most compelling evidence for the role of angiogenesis in tumor growth. Other cancers
that are associated with neovascularization include hemangioendotheliomas, hemangiomas
and Kaposi's sarcoma.
[0024] Proliferation of endothelial and vascular smooth muscle cells is the main feature
of neovascularization. The invention is useful in inhibiting such proliferation, and
therefore in inhibiting or arresting altogether the progression of the angiogenic
condition which depends in whole or in part upon such neovascularization. The invention
is particularly useful when the condition has an additional element of endothelial
or vascular smooth muscle cell proliferation that is not necessarily associated with
neovascularization. For example, psoriasis may additionally involve endothelial cell
proliferation that is independent of the endothelial cell proliferation associated
with neovascularization. Likewise, a solid tumor which requires neovascularization
for continued growth may also be a tumor of endothelial or vascular smooth muscle
cells. In this case, growth of the tumor cells themselves, as well as the neovascularization,
is inhibited by the compounds described herein.
[0025] The invention is also useful for the treatment of fibrotic disorders such as fibrosis
and other medical complications of fibrosis which result in whole or in part from
the proliferation of fibroblasts. Medical conditions involving fibrosis (other than
atherosclerosis, discussed below) include undesirable tissue adhesion resulting from
surgery or injury.
[0026] Vascular injury can also result in endothelial and vascular smooth muscle cell proliferation.
The injury can be caused by any number of traumatic events or interventions, including
vascular surgery and balloon angioplasty. Restenosis is the main complication of successful
balloon angioplasty of the coronary arteries. It is believed to be caused by the release
of growth factors as a result of mechanical injury to the endothelial cells lining
the coronary arteries. Thus, by inhibiting unwanted endothelial and smooth muscle
cell proliferation, the compounds described herein can be used to delay, or even avoid,
the onset of restenosis.
[0027] Other conditions which can be treated or prevented by means of the present invention
include diseases of the arterial walls that involve proliferation of endothelial and/or
vascular smooth muscle cells, such as complications of diabetes, diabetic glomerulosclerosis
and diabetic retinopathy.
[0028] The compounds described herein are also useful in treating or preventing various
types of cancers. Cancers which can be treated by means of the present invention include,
but are not limited to, biliary tract cancer; brain cancer, including glioblastomas
and medulloblastomas; breast cancer; cervical cancer; choriocarcinoma; colon cancer;
endometrial cancer; esophageal cancer; gastric cancer; hematological neoplasms, including
acute and chronic lymphocytic and myelogenous leukemia, multiple myeloma, AIDS associated
leukemias and adult T-cell leukemia lymphoma; intraepithelial neoplasms, including
Bowen's disease and Paget's disease; liver cancer; lung cancer; lymphomas, including
Hodgkin's disease and lymphocytic lymphomas; neuroblastomas; oral cancer, including
squamous cell carcinoma; ovarian cancer, including those arising from epithelial cells,
stromal cells, germ cells and mesenchymal cells; pancreas cancer; prostate cancer;
rectal cancer; sarcomas, including leiomyosarcoma, rhabdomyosarcoma, liposarcoma,
fibrosarcoma and osteosarcoma; skin cancer, including melanoma, Kaposi's sarcoma,
basocellular cancer and squamous cell cancer; testicular cancer, including germinal
tumors (seminoma, non-seminoma (teratomas, choriocarcinomas)), stromal tumors and
germ cell tumors; thyroid cancer, including thyroid adenocarcinoma and medullar carcinoma;
and renal cancer including adenocarcinoma and Wilms tumor.
[0029] The compounds of the invention are useful with hormone dependent and also with nonhormone
dependent cancers. They also are useful with prostate and nonprostate cancers and
with breast and nonbreast cancers. They further are useful with multidrug resistant
strains of cancer.
[0030] In addition to the particular disorders enumerated above, the invention is also useful
in treating or preventing dermatological diseases including keloids, hypertrophic
scars, seborrheic dermatosis, papilloma virus infection (
e.
g., producing verruca vulgaris, verruca plantaris, verruca plan, condylomata, etc.),
eczema and epithelial precancerous lesions such as actinic keratosis; other inflammatory
diseases including proliferative glomerulonephritis; lupus erythematosus; scleroderma;
temporal arthritis; thromboangiitis obliterans; mucocutaneous lymph node syndrome;
and other pathologies mediated by growth factors including uterine leiomyomas.
[0031] The compounds of the invention provide myriad advantages over agents commonly used
to treat sickle cell disease and/or cell proliferative disorders. The compounds of
the invention also provide myriad advantages over the treatment of cell proliferative
disorders with Clotrimazole or other antimycotic agents. For example, many of the
compounds of the invention are more potent than Clotrimazole in
in vitro tests, and therefore may provide consequential therapeutic advantages in clinical
settings.
[0032] Most significantly, the compounds of the invention have reduced toxicity as compared
with these other agents. For Clotrimazole, it is well-known that the imidazole moiety
is responsible for inhibiting a wide range of cytochrome P-450 isozyme catalyzed reactions,
which constitutes their main toxicological effects (Pappas and Franklin, 1993,
Toxicology 80:27-35; Matsuura
et al., 1991,
Biochemical Pharmacology 41:1949-1956). Analogues and metabolites of Clotrimazole do not induce cytochrome P-450
(Matsuura
et al., 1991,
Biochemical Pharmacology 41:1949-1956), and therefore do not share Clotrimazole's toxicity.

cell proliferation may be determined using standard techniques. Preferentially, a
compound is subject to a series of screens to determine its pharmacological activity.
[0051] In most cases, the active compounds of the invention exhibit two pharmacological
activities: inhibition of the Gardos channel of erythrocytes and inhibition of mammalian
cell proliferation. However, in some cases, the compounds of the invention may exhibit
only one of these pharmacological activities. Any compound encompassed by formula
(I) which exhibits at least one of these pharmacological activities is considered
to be within the scope of the present invention.
[0052] In general, the active compounds of the invention are those which induce at least
about 25% inhibition of the Gardos channel of erythrocytes (measured at about 10 µM)
and/or about 25% inhibition of mammalian cell proliferation (measured at about 10
µM), as measured using
in vitro assays that are commonly known in the art (
see, e.
g., Brugnara
et al., 1993,
J. Biol. Chem. 268(12):8760-8768; Benzaquen
et al., 1995,
Nature Medicine 1:534-540). Alternatively, or in addition, the active compounds of the invention generally
will have an IC
50 (concentration of compound that yields 50% inhibition) for inhibition of the Gardos
channel of less than about 10 µM and/or an IC
50 for inhibition of cell proliferation of less than about 10 µM, as measured using
in vitro assays that are commonly known in the art (

[0075] The active compound(s) may be administered per se or in the form of a pharmaceutical
composition wherein the active compound(s) is in admixture with one or more pharmaceutically
acceptable carriers, excipients or diluents. Pharmaceutical compositions for use in
accordance with the present invention may be formulated in conventional manner using
one or more physiologically acceptable carriers comprising excipients and auxiliaries
which facilitate processing of the active compounds into preparations which can be
used pharmaceutically. Proper formulation is dependent upon the route of administration
chosen.
[0076] For injection, the agents of the invention may be formulated in aqueous solutions,
preferably in physiologically compatible buffers such as Hanks's solution, Ringer's
solution, or physiological saline buffer. For transmucosal administration, penetrants
appropriate to the barrier to be permeated are used in the formulation. Such penetrants
are generally known in the art.
[0077] For oral administration, the compounds can be formulated readily by combining the
active compound(s) with pharmaceutically acceptable carriers well known in the art.
Such carriers enable the compounds of the invention to be formulated as tablets, pills,
dragees, capsules, liquids, gels, syrups, slurries, suspensions and the like, for
oral ingestion by a patient to be treated. Pharmaceutical preparations for oral use
can be obtained solid excipient, optionally grinding a resulting mixture, and processing
the mixture of granules, after adding suitable auxiliaries, if desired, to obtain
tablets or dragee cores. Suitable excipients are, in particular, fillers such as sugars,
including lactose, sucrose, mannitol, or sorbitol; cellulose preparations such as,
for example, maize starch, wheat starch, rice starch, potato starch, gelatin, gum
tragacanth, methyl cellulose, hydroxypropylmethyl-cellulose, sodium carboxymethylcellulose,
and/or polyvinylpyrrolidone (PVP). If desired, disintegrating agents may be added,
such as the cross-linked polyvinyl pyrrolidone, agar, or alginic acid or a salt thereof
such as sodium alginate.
[0078] Dragee cores are provided with suitable coatings. For this purpose, concentrated
sugar solutions may be used, which may optionally contain gum arabic, talc, polyvinyl
pyrrolidone, carbopol gel, polyethylene glycol, and/or titanium dioxide, lacquer solutions,
and suitable organic solvents or solvent mixtures. Dyestuffs or pigments may be added
to the tablets or dragee coatings for identification or to characterize different
combinations of active compound doses.
[0079] Pharmaceutical preparations which can be used orally include push-fit capsules made
of gelatin, as well as soft, sealed capsules made of gelatin and a plasticizer, such
as glycerol or sorbitol. The push-fit capsules can contain the active ingredients
in admixture with filler such as lactose, binders such as starches, and/or lubricants
such as talc or magnesium stearate and, optionally, stabilizers. In soft capsules,
the active compounds may be dissolved or suspended in suitable liquids, such as fatty
oils, liquid paraffin, or liquid polyethylene glycols. In addition, stabilizers may
be added. All formulations for oral administration should be in dosages suitable for
such administration.
[0080] For buccal administration,the compositions may take the form of tablets or lozenges
formulated in conventional manner.
[0081] For administration by inhalation, the compounds for use according to the present
invention are conveniently delivered in the form of an aerosol spray presentation
from pressurized packs or a nebulizer, with the use of a suitable propellant,
e.g., dichlorodifluoromethane, trichlorofluoromethane, dichlorotetrafluoroethane, carbon
dioxide or other suitable gas. In the case of a pressurized aerosol the dosage unit
may be determined by providing a valve to deliver a metered amount. Capsules and cartridges
of e.g. gelatin for use in an inhaler or insufflator may be formulated containing
a powder mix of the compound and a suitable powder base such as lactose or starch.
[0082] The compounds may be formulated for parenteral administration by injection,
e.g., by bolus injection or continuous infusion. Formulations for injection may be presented
in unit dosage form,
e.g., in ampoules or in multidose containers, with an added preservative. The compositions
may take such forms as suspensions, solutions or emulsions in oily or aqueous vehicles,
and may contain formulatory agents such as suspending, stabilizing and/or dispersing
agents.
[0083] Pharmaceutical formulations for parenteral administration include aqueous solutions
of the active compounds in water-soluble form. Additionally, suspensions of the active
compounds may be prepared as appropriate oily injection suspensions. Suitable lipophilic
solvents or vehicles include fatty oils such as sesame oil, or synthetic fatty acid
esters, such as ethyl oleate or triglycerides, or liposomes. Aqueous injection suspensions
may contain substances which increase the viscosity of the suspension, such as sodium
carboxymethyl cellulose, sorbitol, or dextran. Optionally, the suspension may also
contain suitable stabilizers or agents which increase the solubility of the compounds
to allow for the preparation of highly concentrated solutions.
[0084] Alternatively, the active ingredient may be in powder form for constitution with
a suitable vehicle, e.g., sterile pyrogen-free water, before use.
[0085] The compounds may also be formulated in rectal compositions such as suppositories
or retention enemas,
e.g., containing conventional suppository bases such as cocoa butter or other glycerides.
[0086] In addition to the formulations described previously, the compounds may also be formulated
as a depot preparation. Such long acting formulations may be administered by implantation
or transcutaneous delivery (for example subcutaneously or intramuscularly), intramuscular
injection or a transdermal patch. Thus, for example, the compounds may be formulated
with suitable polymeric or hydrophobic materials (for example as an emulsion in an
acceptable oil) or ion exchange resins, or as sparingly soluble derivatives, for example,
as a sparingly soluble salt.
[0087] The pharmaceutical compositions also may comprise suitable solid or gel phase carriers
or excipients. Examples of such carriers or excipients include but are not limited
to calcium carbonate, calcium phosphate, various sugars, starches, cellulose derivatives,
gelatin, and polymers such as polyethylene glycols.
5.3 Effective Dosages
[0088] Pharmaceutical compositions suitable for use with the present invention include compositions
wherein the active ingredient is contained in a therapeutically effective amount,
i.e., in an amount effective to achieve its intended purpose. Of course, the actual
amount effective for a particular application will depend, inter alia, on the condition
being treated. When administered in methods to inhibit cell proliferation, such compositions
will contain an amount of active ingredient effective to achieve this result. When
administered to patients suffering from disorders characterized by abnormal cell proliferation,
such compositions will contain an amount of active ingredient effective to,
inter alia, prevent the development of or alleviate the existing symptoms of, or prolong the
survival of, the patient being treated. For use in the treatment of cancer, a therapeutically
effective amount further includes that amount of compound which arrests or regresses
the growth of a tumor. Determination of an effective amount is well within the capabilities
of those-skilled in the art, especially in light of the detailed disclosure herein.
[0089] For any compound described herein the therapeutically effective amount can be initially
determined from cell culture arrays. Target plasma concentrations will be those concentrations
of active compound(s) that are capable of inducing at least about 25% inhibition of
cell proliferation in cell culture assays, depending, of course, on the particular
desired application. Target plasma concentrations of active compound(s) that are capable
of inducing at least about 50%, 75%, or even 900 or higher inhibition of the cell
proliferation in cell culture assays are preferred. The percentage of inhibition of
the cell proliferation in the patient can be monitored to assess the appropriateness
of the plasma drug concentration achieved, and the dosage can be adjusted upwards
or downwards to achieve the desired percentage of inhibition.
[0090] Therapeutically effective amounts for use in humans can also be determined from animal
models. For example, a dose for humans can be formulated to achieve a circulating
concentration that has been found to be effective in animals. A particularly useful
animal model for sickle cell disease is the SAD mouse model (Trudel et al., 1991,
EMBO J. 11:315725 3165). Useful animal models for diseases characterized by abnormal cell
proliferation are well-known in the art. In particular, the following references provide
suitable animal models for cancer xenografts (Corbett
et al., 1996,
J. Exp. Ther. Oncol. 1:95-108; Dykes et
al., 1992,
Contrib. oncol. Basel. Karger 42:1-22), restenosis (Carter
et al., 1994, J.
Am. Coll. Cardiol. 24(5):1398-1405), atherosclerosis (Zhu
et al., 1994,
Cardiology 85(6):370-377) and neovascularization (Epstein
et al., 1987, Cornea 6(4):250-257). The dosage in humans can be adjusted by monitoring
inhibition of cell proliferation and adjusting the dosage upwards or downwards, as
described above.
[0091] A therapeutically effective dose can also be determined from human data for compounds
which are known to exhibit similar pharmacological activities, such as Clotrimazole
and other antimycotic agents (see,
e.g., Brugnara
et al., 1995,
JPET 273:266-272; Benzaquen
et al., 1995,
Nature Medicine 1:534-540; Brugnara
et al., 1996,
J. Clin. Invest. 97(5):1227-1234). The applied dose can be adjusted based on the relative bioavailability
and potency of the administered compound as compared with Clotrimazole.
[0092] Adjusting the dose to achieve maximal efficacy in humans based on the methods described
above and other methods as are well-known in the art is well within the capabilities
of the ordinarily skilled artisan.
[0093] Of course, in the case of local administration, the systemic circulating concentration
of administered compound will not be of particular importance. In such instances,
the compound is administered so as to achieve a concentration at the local area effective
to achieve the intended result.
[0094] For use in the treatment of disorders characterized by abnormal cell proliferation,
including cancer, arteriosclerosis and angiogenic conditions such as restenosis, a
circulating concentration of administered compound of about 0.001 µM to 20 µM is considered
to be effective, with about 0.1 µM to 5 µM being preferred.
[0095] Patient doses for oral administration of the compounds described herein for the treatment
or prevention of cell proliferative disorders typically range from about 80 mg/day
to 16,000 mg/day, more typically from about 800 mg/day to 8000 mg/day, and most typically
from about 800 mg/day to 4000 mg/day. Stated in terms of patient body weight, typical
dosages range from about 1 to 200 mg/kg/day, more typically from about 10 to 100 mg/kg/day,
and most typically from about 10 to 50 mg/kg/day. Stated in terms of patient body
surface areas, typical dosages range from about 40 to 8000 mg/m
2/day, more typically from about 400 to 4000 mg/m
2/day, and most typically from about 400 to 2000 mg/m
2/day.
[0096] For other modes of administration, dosage amount and interval can be adjusted individually
to provide plasma levels of the administered compound effective for the particular
clinical indication being treated.
[0097] For use in the treatment of tumorigenic cancers, the compounds can be administered
before, during or after surgical removal of the tumor. For example, the compounds
can be administered to the tumor via injection into the tumor mass prior to surgery
in a single or several doses. The tumor, or as much as possible of the tumor, may
then be removed surgically. Further dosages of the drug at the tumor site can be applied
post removal. Alternatively, surgical removal of as much as possible of the tumor
can precede administration of the compounds at the tumor site.
[0098] Combined with the teachings provided herein, by choosing among the various active
compounds and weighing factors such as potency, relative bioavailability, patient
body weight, severity of adverse side-effects and preferred mode of administration,
an effective prophylactic or therapeutic treatment regimen can be planned which does
not cause substantial toxicity and yet is entirely effective to treat the clinical
symptoms demonstrated by the particular patient. Of course, many factors are important
in determining a therapeutic regimen suitable for a particular indication or patient.
Severe indications such as cancer may warrant administration of higher dosages as
compared with less severe indications such as sickle cell disease.
5.4 Toxicity
[0099] The ratio between toxicity and therapeutic effect for a particular compound is its
therapeutic index and can be expressed as the ratio between LD
50 (the amount of compound lethal in 50% of the population) and ED
50 (the amount of compound effective in 50% of the population). Compounds which exhibit
high therapeutic indices are preferred. Therapeutic index data obtained from cell
culture assays and/or animal studies can be used in formulating a range of dosages
for use in humans. The dosage of such compounds preferably lies within a range of
plasma concentrations that include the ED
50 with little or no toxicity. The dosage may vary within this range depending upon
the dosage form employed and the route of administration utilized. The exact formulation,
route of administration and dosage can be chosen by the individual physician in view
of the patient's condition. (See
e.g. Fingl
et al., 1975,
In:
The Pharmacological Basis of Therapeutics, Ch. 1 pl).
[0100] The invention having been described, the following examples are intended to illustrate,
not limit, the invention.
6. EXAMPLE: Compound Syntheses
[0101] This Example demonstrates general methods of synthesis for many of the preferred
compounds of the invention, as well as preferred methods of synthesis for certain
exemplary compounds of the invention.
6.1 Synthesis of Triphenylmethanols
[0102] A general method of synthesis of triphenylmethanol derivatives is as follows: A mixture
of substituted benzoyl chloride (1 equivalent), substituted benzene (1 equivalent),
and aluminum chloride (1.1 equivalent), in methylene chloride was stirred at room
temperature for 1 hour. The reaction mixture was cooled in an ice bath and water was
added. The layers were separated and the aqueous layer extracted with methylene chloride.
The combined methylene chloride extracts were washed with water and saturated aqueous
sodium bicarbonate and then dried over sodium sulfate. Evaporation of the solvent
gave the substituted benzophenone in 80-95% yield. The substituted benzophenone (1
equivalent) and substituted phenylmagnesium bromide (1.1 equivalent) in tetrahydrofuran
was refluxed for 5 hours, cooled in an ice bath and water added. The reaction mixture
was extracted with methylene chloride and the combined extracts were dried over sodium
sulfate. Evaporation of the solvent followed by column chromatography gave the substituted
triphenylmethanol in 45-90% yield.
6.2 Synthesis of Triphenylpropionic acids
6.2.1 Method A
[0103] One method of synthesis of triphenylpropionic acid derivatives is as follows: A mixture
of substituted triphenylmethanol (1 equivalent) and malonic acid (2-3 equivalents)
was stirred without solvent at 170 °C for 3 hour. After cooling, aqueous 1.0 M sodium
hydroxide was added to the reaction mixture. This mixture was stirred at 90 °C for
4 hours and then filtered hot. Acidification of the cooled filtrate with 1.0 M hydrochloric
acid caused precipitation of a white product which was collected by suction filtration
in 20-40% yield.
6.2.2 Method B
[0104] A second method of synthesis of triphenylpropionic acid derivatives is as follows:
A mixture of magnesium (1.1 equivalent) and diethyl malonate (1.1 equivalent) in anhydrous
ethanol was heated at reflux until all the magnesium was consumed (approximately 2
hours). Evaporation of the solvent gave a clear oil to which substituted triphenylmethane
(obtained by reduction of the substituted triphenylmethanol by the method of Ando
& Ikeno, 1979,
Tetrahedron. Lett. 51:4941) (1 equivalent) and benzene was added. The mixture was refluxed for 5 minutes and
then stirred at ambient temperature for 3 hours. Hydrochloric acid (0.1 M) was added
and the mixture stirred at room temperature overnight. The organic layer was separated,
washed with water and dried over sodium sulfate. Evaporation gave the intermediate
diethyl-substituted-diphenyl-benzylmalonate in 50-90% yield. In the final step, this
intermediate (1 equivalent) and potassium hydroxide (6 equivalents) in ethanol was
refluxed for 9 hours. The solvent was removed in vacuo, water added, and the solution
stirred at 65 °C for 1 hour. The cooled solution was acidified with 1.0 M hydrochloric
acid causing precipitation of a white solid. The solid was collected by suction filtration
to give the desired substituted triphenylpropionic acid in 60-90% yield.

[0126] A preferred method of synthesis of 3-(2-chlorophenyl)-3,3-diphenylpropionic acid
(Compound 36) is as follows: A mixture of 1.7 g (0.07 mole) of magnesium and 11.2
g (0.07 mole) of diethyl malonate in 25 mL anhydrous ethanol was heated at reflux
until all the magnesium was consumed (approximately 2 hours). Evaporation of the solvent
gave a clear oil to which 20 g (0.064) of chloro-(2-chlorophenyl)-diphenylmethane
and 100 mL benzene was added. The mixture was refluxed for 5 minutes and then stirred
at ambient temperature for 3 hours. Water (90 mL) and 10 mL of 1.0 M hydrochloric

7. EXAMPLE: In Vitro Activity
[0158] This Example demonstrates the ability of several exemplary compounds of formula (I)
to inhibit the Gardos channel of erythrocytes and/or mitogen-induced cell proliferation
in vitro. The assays are generally applicable for demonstrating the
in vitro activity of other compounds of formula (I).
7.1 Experimental Protocol
[0159] The percent inhibition of the Gardos channel (10 µM compound) and the IC
50 were determined as described in Brugnara
et al., 1993,
J. Biol. Chem. 268(12):8760-8768. The percent inhibition of mitogen-induced cell proliferation (10 µM
compound) and the IC
50 were determined or described in Benzaquen
et al. (1995,
Nature Medicine 1:534-540) with NIH 3T3 mouse fibroblast cells (ATCC No. CRL 1658). Clotrimazole is
reported for purposes of comparison. Other cell lines, e.g., cancer cells, endothelial
cells and fibroblasts, as well as many others, may be used in the cell proliferation
assay. Selection of a particular cell line will depend in part on the desired application,
and is well within the capabilities of an ordinarily skilled artisan.

8. EXAMPLE: Clotrimazole Metabolite B (Compound 6) Displaces Bound 125I-ChTX
[0161] Charybdotoxin (ChTX), a peptide of 37 amino acids in length, is a potent inhibitor
of many Ca
2+-activated and voltage-gated K
+ channels, including the Gardos channel (Miller
et al., 1985,
Nature 313:316-318; Bontems
et al., 1992,
Biochemistry 31:7756-7764; Park
et al., 1991,
Proc. Natl. Acad. Sci. U.S.A.
88:2046-2050; Vazquez
et al., 1989,
J. Biol. Chem. 264:20902-20909; Grinstein and Smith, 1990,
J. Gen. Physiol.
95:97-120; Brugnara
et al., 1993,
J. Biol. Chem. 268:8760-8768). Because bound ChTX inhibitor may be competitively displaced by other Gardos channel
inhibitors, ChTX is an important tool for understanding Gardos channel function and
activation. This example demonstrates displacement of ChTX by CLT metabolite B (Compound
6). The method described herein is generally applicable for demonstrating the ability
of other compounds of formula (I) to competitively displace ChTX.
8.1 125ChTX binding to red cells
[0162] White cells were removed by passing 0.8 mL of packed red cells through a 5 mL syringe
containing a mixture of equal parts of alpha-cellulose and microcrystalline cellulose
as originally described by Beutler and West, 1976,
J. Lab. Clin. Med. 88:328-333. Red cells were washed three times in binding medium containing 18mM NaCl,
2mM KCl, 10mM tris-Cl, pH 8.0, 230 mM sucrose and 0.25% bovine serum albumin. A suspension
was then made in the same medium at 15% Hematocrit (HCt). Cells were added to 3.5
ml of binding medium containing
125IChTX to a final concentration of 1 X 10
7 cells/mL, in the absence or presence of the specified drugs. Tubes containing cell
suspension were gently rotated for 90 min. at room temperature. At the end of the
incubation, aliquots of 1 ml were pelleted by microfuge and washed 3 times at 4°C
with a solution containing 200 mM NaCl, 10mM tris-Cl, pH 8.0. The washed red cell
pellet was then lysed in 1 ml of 0.01% Acationox (American scientific Products), and
counted in a gamma counter. Aliquots of binding medium were counted prior to addition
of cells at the end of the binding assay.
8.2 Displacement by Metabolite B (Compound 6)
[0163] Metabolite B (Compound
6) was added to the red cells from a stock solution in acetonitrile. A similar amount
of acetonitrile was added to each control tube. Specific binding was estimated on
the basis of displacement of
125I-ChTX by 50 nM unlabeled ChTX. Various concentrations of metabolite B (Compound
6) or unlabeled ChTX were added to the cell suspension (1x10
7 cells/mL) prior to the addition of
125I-ChTX.
8.3 Results
[0164] The results of the assay are depicted in TABLE 2. Metabolite B (Compound
6) specifically displaces
125IChTX binding.

9. EXAMPLE: Clotrimazole and Its Metabolites Inhibit Ca2+-Activated Potassium Transport In Vivo In Humans
[0165] This Example demonstrates the ability of Clotrimazole (CLT) and CLT metabolites A
and B (Compounds
17 and
6, respectively) to inhibit the Gardos channel of erythrocytes
in vivo in humans. The methods described herein are generally applicable for demonstrating
the
in vivo activity of other compounds of formula (I) when administered to humans.
9.1 Experimental Protocol
[0166] Two subjects, one male (A, 72 Kg) and one female (D, 56 Kg), ingested one 500mg CLT
tablet every twelve hours for six days, corresponding to a daily CLT dose of 14 and
18 mg/kg, respectively. Blood was collected six hours after the AM dose of CLT on
days 3 and 6 for measurement of inhibition of red cell calcium-activated potassium
transport.
9.2 Results
[0167] TABLE 3 depicts the results of the measurement of the red cell calcium-activated
potassium transport in the two normal subjects. As shown in TABLE 3, there was significant
inhibition of calcium-activated potassium transport during CLT administration, which
persisted for at least 7 days after the drugs were discontinued. At day 6, plasma
CLT concentration was 0.2 µM with combined metabolite levels of 2.9 µM (subject A)
and 3.85 µM (subject D). There was no evidence of CLT or CLT-metabolites in plasma
two days after CLT administration was stopped.

[0168] Measurements of whole blood CLT levels allowed estimation of "blood cell-associated"
CLT levels. As shown in TABLE 3, significant levels of "blood cell-associated CLT
were detected up to 7 days (subject A) and 14 days (subject D) following CLT withdrawal.
There were no metabolites detectable in blood cells 2 days after CLT was discontinued.
These data suggest that red cells and possibly other blood elements bind or contain
a significant amount of CLT for an extended period of time, even in the absence of
measurable plasma levels. CLT metabolites show a different behavior, disappearing
at the same time from both plasma and cells.
[0169] There was a significant correlation between summed levels of CLT and its metabolites
in cells and the percent inhibition of the Gardos channel measured in whole blood
[% inhibition = 31.7 log (CLT + Met A + Met B, µM) + 56.4; r
2=0.439, t=3.06, p<0.02, n=14].
[0170] Metabolite B (Compound
6) specifically inhibits potassium transport via the red cell Gardos channel. CLT and
metabolite B (Compound
6) were incubated with a red cell suspension at 20% Hct. Comparison of the inhibitory
effect on the red cell Gardos channel of CLT and metabolite B (Compound
6) shows IC
50 values of 310 ± 63 nM for CLT and 720 ± 190nM for metabolite B (Compound
6). The value for the inhibition of K
+ transport by metabolite B (Compound
6) is two to three fold lower than the IC
50 for displacement of
125I-ChTx by metabolite B (Compound
6). It has previously been shown, (Brugnara, 1993, supra) for ChTX that there is a
two to three fold increase in the IC
50 value for displacement of
125I-ChTX by ChTX compared with the inhibition of K
+ transport by ChTX.
[0171] Inhibition of K
+ transport was measured by varying concentrations of metabolite B (Compound
6) and CLT, and the results are depicted in TABLE 4. The percent inhibition of K-transport
was greater than 50% when the cells were treated with 500 nM CLT or 1 µM metabolite
B (Compound
6) and reached maximal levels at 5 µM CLT and 10 µM metabolite B (Compound
6).
[0172] Oral administration of CLT was not associated with significant side effects in any
of the subject studied. In particular no nausea, vomiting or diarrhea were observed.
No changes were observed in liver function tests, plasma creatine or blood urea nitrogen
(BUN).

10. EXAMPLE: Metabolite B (compound 6) Inhibits Mitogen-Induced Cell Proliferation In Vitro In Various Cell Lines
[0173] This Example demonstrates the ability of Clotrimazole (CLT) metabolite B (Compound
6) to inhibit mitogen-induced cell proliferation in various cell lines, including cancer
cells. Such assays are generally applicable for demonstrating the activities of other
compounds of formula (I) in various cell lines.
10.1 Experimental Protocol
[0174] Human melanoma cells (MM-RU) and colon adenocarcinoma cells (HT29) were cultured
in the presence and absence of 10 µM CLT metabolite B (Compound
6) as described in Benzaquen
et al., 1995,
Nature Medicine 1:534-540 and the level of DNA synthesis determined by measuring [
3H]thymidine uptake.
10.2 Results
[0175] CLT metabolite B (Compound
6) was a potent inhibitor of proliferation of these cell lines
in vitro. Specifically, CLT metabolite B (Compound
6) inhibited [
3H]thymidine uptake by about 60% versus controls in MM-RU cells and by about 50% versus
controls in HT29 cells.
11. EXAMPLE: CLT Inhibits Cell Proliferation In Vivo
[0176] This Example demonstrates the ability of Clotrimazole (CLT) to inhibit cell proliferation
in an
in vivo animal model of human melanoma. Such an animal model is contemplated to be applicable
for demonstrating the
in vivo activity of compounds of formula (I) which inhibit MM-RU cells
in vitro.
11.1 Experimental Protocol
[0177] Mice with severe combined immunodeficiency disease (SCID) were inoculated via the
lateral tail vein with approximately 2.5 x 10
6 MM-RU human melanoma cells, a cell line that produces metastases only in the lungs
(Byers
et al., 1993,
Melanoma Res. 3:247-253). Starting on the day of inoculation, subcutaneous injections of either vehicle
(control group, n=9) or CLT (120 mg/Kg; treatment group, n=10) was administered daily
for a period of 10 weeks. At the end of the 10 week treatment period, the mice were
sacrificed and examined for metastases.
11.2 Results
[0178] Ten weeks after inoculation of MM-RU cells, all animals in the control group had
developed pleural macroscopic and microscopic lung metastases. In stark contrast,
half of the CLT-treated animals were free of macroscopic metastases, and two did not
even exhibit evidence of microscopic metastases.
[0179] Despite the variability in the number of metastases observed within each group, animals
in the CLT-treated group exhibited significantly fewer pleural (14 ± 4 in control
vs. 2 ± 1 in treated animals; P < 0.05) and microscopic (27 ± 9 in control vs. 7 ±
2 in treated animals; P < 0.05) metastases than those in the control group. A greater
number of metastases were counted in the microscopic sections than on the pleural
surface, as is typical of the SCID-mice/MM-RU-cells model. There was an excellent
correlation between both methods of counting (r = 0.90). Consistent with the high
organ specificity for lung tissue of the MM-RU melanoma cells, other organs did not
show any histological evidence of metastatic lesions.
[0180] Animals in the control and treatment groups did not show any evidence of systemic
metastatic disease or toxicity; both control and CLT-treated animals gained weight
in comparable amounts.
[0181] In vivo efficacy in this mouse melanoma model can be demonstrated with other compounds of
formula (I) which inhibit MM-RU cells
in vitro as well.
12. EXAMPLE: Formulations
