1. Field of the Invention
The invention provides compounds, pharmaceutical compositions comprising such compounds and methods of using such compounds to treat or prevent diseases or disorders associated with the activation of steroid hormone nuclear receptors and calcium channel blockade activity.
2. Background
Steroid hormone receptors represent a subset of the nuclear hormone receptor superfamily. So named according to the cognate ligand which complexes with the receptor in its native state, the steroid hormone nuclear receptors include the glucocorticoid receptor (GR), the androgen receptor (AR), the mineralocorticoid receptor (MR), the estrogen receptor (ER), and the progesterone receptor (PR). MR is expressed in epithelial tissues, heart, kidneys, brain, vascular tissues and bone. Aldosterone is the endogenous ligand of MR and is primarily synthesized in the adrenal glands, heart, brain and blood vessels. Several detrimental effects are attributable to aldosterone, for example: sodium/water retention, renal fibrosis, vascular inflammation, vascular fibrosis, endothelial dysfunction, coronary inflammation, decrease in coronary blood flow, ventricular arrhythmias, myocardial fibrosis, ventricular hypertrophy and direct damage to cardiovascular systems, primarily the heart, vasculature and kidneys. Aldosterone action on all target organs is through activation of the MR receptor. GR is expressed in almost all tissues and organ systems and is crucial for the integrity of the function of the central nervous system and the maintenance of cardiovascular, metabolic, and immune homeostasis.
Calcium channel antagonists have long been used as drugs to treat various cardiovascular diseases like coronary vasodilation, angina, arrythmias, congestive heart failure, cardiomyopathy, atheriosclerosis and high blood pressure.
The novel compounds of the invention modulate the activity of the steroid hormone nuclear receptors and calcium channels and are, therefore, expected to be useful in the treatment of diseases in which aberrant activity of steroidal nuclear hormone receptors and/or calcium channels contribute to the pathology and/or symptomatology of the disease.

Mineralocorticoids and glucocorticoids exert profound influences on a multitude of physiological functions by virtue of their diverse roles in growth, development, and maintenance of homeostasis. Their actions are mediated by the MR and GR.
In visceral tissues, such as the kidney and the gut, MR regulates sodium retention, potassium excretion, and water balance in response to aldosterone. Elevations in aldosterone levels, or excess stimulation of mineralocorticoid receptors, are linked to several pathological disorders or pathological disease states including, Conn's Syndrome, primary and secondary hyperaldosteronism, increased sodium retention, increased magnesium and potassium excretion (diuresis), increased water retention, hypertension (isolated systolic and combined systolic/diastolic), arrhythmias, myocardial fibrosis, myocardial infarction, Barter's Syndrome, congestive heart failure (CHF), and disorders associated with excess catecholamine levels. In addition, MR expression in the brain appears to play a role in the control of neuronal excitability, in the negative feedback regulation of the hypothalamic-pituitary-adrenal axis, and in the cognitive aspects of behavioral performance. Further, aldosterone antagonists are useful in the treatment of subjects suffering from one or more cognitive dysfunctions including, but not limited to psychoses, cognitive disorders (such as memory disturbances), mood disorders (such as depression and bipolar disorder), anxiety disorders, and personality disorders. In particular, mineralocorticoid receptors, and modulation of MR activity, are involved in anxiety and major depression. Finally, expression of MR may be related to differentiation of breast carcinomas. Thus MR modulators may also have utility in treating cancer, particularly of the breast.
GR is expressed in almost all tissues and organ systems and is crucial for the integrity of the function of the central nervous system and the maintenance of cardiovascular, metabolic, and immune homeostasis. Glucocorticoids (e.g. cortisol, corticosterone, and cortisone), and the glucocorticoid receptor, have been implicated in the etiology of a variety of pathological disorders or pathologic disease states. For example, cortisol hypo-secretion is implicated in the pathogenesis of diseases resulting in muscle weakness, increased melanin pigmentation of the skin, weight loss, hypotension, and hypoglycemia. On the other hand, excessive or prolonged secretion of glucocorticoids has been correlated to Cushing's Syndrome and can also result in obesity, hypertension, glucose intolerance, hyperglycemia, diabetes mellitus, osteoporosis, polyuria, and polydipsia.
Further, GR selective agents could modulate GR activity and, thus, be useful in the treatment of inflammation, tissue rejection, auto-immunity, malignancies such as leukemias and lymphomas, Cushing's syndrome, acute adrenal insufficiency, congenital adrenal hyperplasia, rheumatic fever, polyarteritis nodosa, granulomatous polyarteritis, inhibition of myeloid cell lines, immune proliferation/apoptosis, HPA axis suppression and regulation, hypercortisolemia, modulation of the Th1/Th2 cytokine balance, chronic kidney disease, stroke and spinal cord injury, hypocalcaemia, hyperglycemia, acute adrenal insufficiency, chronic primary adrenal insufficiency, secondary adrenal insufficiency, congenital adrenal hyperplasia, cerebral edema, thrombocytopenia, and Little's syndrome. It has been reported that GR modulators are especially useful in disease states involving systemic inflammation such as inflammatory bowel disease, systemic lupus erythematosus, polyartitis nodosa, Wegener's granulomatosis, giant cell arthritis, rheumatoid arthritis, osteoarthritis, hay fever, allergic rhinitis, urticaria, angioneurotic edema, chronic obstructive pulmonary disease, asthma, tendonitis, bursitis, Crohn's disease, ulcerative colitis, autoimmune chronic active hepatitis, organ transplantation, hepatitis, and cirrhosis; and that GR modulating compounds have been used as immunostimulants, repressors, and as wound healing and tissue repair agents. In addition, GR modulators have also found use in a variety of topical diseases such as inflammatory scalp alopecia, panniculitis, psoriasis, discoid lupus erythematosus, inflamed cysts, atopic dermatitis, pyoderma gangrenosum, pemphigus vulgaris, bullous pemphigoid, systemic lupus erythematosus, dermatomyositis, eosinophilic fasciitis, relapsing polychondritis, inflammatory vasculitis, sarcoidosis, Sweet's disease, type 1 reactive leprosy, capillary hemangiomas, contact dermatitis, atopic dermatitis, lichen planus, exfoliative dermatitis, erythema nodosum, acne, hirsutism, toxic epidermal necrolysis, erythema multiform, and cutaneous T-cell lymphoma. Finally, GR Modulators may also have utility in treating respiratory disorders, such as emphysema, and neuroinflammatory disorders, such as multiple sclerosis and Alzheimer's disease.
Calcium channels are membrane-spanning, multi-subunit proteins that allow calcium entry from the external milieu and concurrent depolarization of the cell's membrane potential. Traditionally, calcium channels have been classified based on their functional characteristics such as low voltage or high voltage activated and their kinetics (L, T, N, P, Q). Calcium channel antagonists have long been used as drugs to treat various diseases, particularly cardiovascular diseases, such as coronary vasodilation, angina, arrhythmias, congestive heart failure, cardiomyopathy, atherosclerosis, high blood pressure and the like. Modulation of calcium channel activity combined to the modulation of the nuclear hormone receptors (especially MR) in the same molecular entity offers an attractive novel way to treat cardiovascular diseases associated with the modulation of both these functional entities.
Accordingly, the present invention provides a method for treating any of the diseases or disorders described above in a subject in need of such treatment, which method comprises administering to said subject a therapeutically effective amount (See, “Administration and Pharmaceutical Compositions”, infra) of a compound of Formula I or a pharmaceutically acceptable salt thereof. For any of the above uses, the required dosage will vary depending on the mode of administration, the particular condition to be treated and the effect desired.
In general, compounds of the invention will be administered in therapeutically effective amounts via any of the usual and acceptable modes known in the art, either singly or in combination with one or more therapeutic agents. A therapeutically effective amount can vary widely depending on the severity of the disease, the age and relative health of the subject, the potency of the compound used and other factors. In general, satisfactory results are indicated to be obtained systemically at daily dosages of from about 0.03 to 2.5 mg/kg of body weight. An indicated daily dosage in the larger mammal, e.g. humans, is in the range from about 0.5 mg to about 100 mg, conveniently administered, e.g. in divided doses up to four times a day or in retard form. Suitable unit dosage forms for oral administration comprise from ca. 1 to 50 mg active ingredient.
Compounds of the invention can be administered as pharmaceutical compositions by any conventional route, in particular enterally, e.g., orally, e.g., in the form of tablets or capsules, or parenterally, e.g., in the form of injectable solutions or suspensions, topically, e.g., in the form of lotions, gels, ointments or creams, or in a nasal or suppository form. Pharmaceutical compositions comprising a compound of the present invention in free form or in a pharmaceutically acceptable salt form in association with at least one pharmaceutically acceptable carrier or diluent can be manufactured in a conventional manner by mixing, granulating or coating methods. For example, oral compositions can be tablets or gelatin capsules comprising the active ingredient together with a) diluents, e.g., lactose, dextrose, sucrose, mannitol, sorbitol, cellulose and/or glycine; b) lubricants, e.g., silica, talcum, stearic acid, its magnesium or calcium salt and/or polyethyleneglycol; for tablets, also c) binders, e.g., magnesium aluminum silicate, starch paste, gelatin, tragacanth, methylcellulose, sodium carboxymethylcellulose and or polyvinylpyrollidone; if desired d) disintegrants, e.g., starches, agar, alginic acid or its sodium salt, or effervescent mixtures; and/or e) absorbents, colorants, flavors and sweeteners. Injectable compositions can be aqueous isotonic solutions or Suspensions, and suppositories can be prepared from fatty emulsions or suspensions. The compositions can be sterilized and/or contain adjuvants, such as preserving, stabilizing, wetting or emulsifying agents, solution promoters, salts for regulating the osmotic pressure and/or buffers. In addition, they can also contain other therapeutically valuable substances. Suitable formulations for transdermal applications include an effective amount of a compound of the present invention with a carrier. A carrier can include absorbable pharmacologically acceptable solvents to assist passage through the skin of the host. For example, transdermal devices are in the form of a bandage comprising a backing member, a reservoir containing the compound optionally with carriers, optionally a rate controlling barrier to deliver the compound to the skin of the host at a controlled and predetermined rate over a prolonged period of time, and means to secure the device to the skin. Matrix transdermal formulations can also be used. Suitable formulations for topical application, e.g., to the skin and eyes, are preferably aqueous solutions, ointments, creams or gels well-known in the art. Such can contain solubilizers, stabilizers, tonicity enhancing agents, buffers and preservatives.
Compounds of the invention can be administered in therapeutically effective amounts in combination with one or more therapeutic agents (pharmaceutical combinations). For example, synergistic effects can occur with other calcium channel blockers and/or other substances used in the treatment of hypokalemia, hypertension, congestive heart failure, renal failure, in particular chronic renal failure, restenosis, atherosclerosis, syndrome X, obesity, nephropathy, post-myocardial infarction, coronary heart disease, increased formation of collagen, fibrosis and remodeling following hypertension and endothelial dysfunction. Examples of such compounds include anti-obesity agents, such as orlistat, anti-hypertensive agents, inotropic agents and hypolipidemic agents e.g., loop diuretics, such as ethacrynic acid, furosemide and torsemide; angiotensin converting enzyme (ACE) inhibitors, such as benazepril, captopril, enalapril, fosinopril, lisinopril, moexipril, perinodopril, quinapril, ramipril and trandolepril; inhibitors of the Na—K-ATPase membrane pump, such as digoxin; neutralendopeptidase (NEP) inhibitors; ACE/NEP inhibitors, such as omapatrilat, sampatrilat, and fasidotril; angiotensin II antagonists, such as candesartan, eprosartan, irbesartan, losartan, telmisartan and valsartan, in particularvalsartan; β-adrenergic receptor blockers, such as acebutolol, betaxolol, bisoprolol, metoprolol, nadolol, propanolol, sotalol and timolol; inotropic agents, such as digoxin, dobutamine and milrinone; calcium channel blockers, such as amlodipine, bepridil, diltiazem, felodipine, nicardipine, nimodipine, nifedipine, nisoldipine and verapamil; and 3-hydroxy-3-methyl-glutaryl coenzyme A reductase (HMG-CoA) inhibitors, such as lovastatin, pitavastatin, simvastatin, pravastatin, cerivastatin, mevastatin, velostatin, fluvastatin, dalvastatin, atorvastatin, rosuvastatin and rivastatin. Where the compounds of the invention are administered in conjunction with other therapies, dosages of the co-administered compounds will of course vary depending on the type of co-drug employed, on the specific drug employed, on the condition being treated and so forth.
The invention also provides for a pharmaceutical combinations, e.g. a kit, comprising a) a first agent which is a compound of the invention as disclosed herein, in free form or in pharmaceutically acceptable salt form, and b) at least one co-agent. The kit can comprise instructions for its administration.
The terms “co-administration” or “combined administration” or the like as utilized herein are meant to encompass administration of the selected therapeutic agents to a single patient, and are intended to include treatment regimens in which the agents are not necessarily administered by the same route of administration or at the same time.
The term “pharmaceutical combination” as used herein means a product that results from the mixing or combining of more than one active ingredient and includes both fixed and non-fixed combinations of the active ingredients. The term “fixed combination” means that the active ingredients, e.g. a compound of Formula I and a co-agent, are both administered to a patient simultaneously in the form of a single entity or dosage. The term “non-fixed combination” means that the active ingredients, e.g. a compound of Formula I and a co-agent, are both administered to a patient as separate entities either simultaneously, concurrently or sequentially with no specific time limits, wherein such administration provides therapeutically effective levels of the 2 compounds in the body of the patient. The latter also applies to cocktail therapy, e.g. the administration of 3 or more active ingredients.
The present invention also includes processes for the preparation of compounds of the invention. In the reactions described, it can be necessary to protect reactive functional groups, for example hydroxy, amino, imino, thio or carboxy groups, where these are desired in the final product, to avoid their unwanted participation in the reactions. Conventional protecting groups can be used in accordance with standard practice, for example, see T. W. Greene and P. G. M. Wuts in “Protective Groups in Organic Chemistry”, John Wiley and Sons, 1991.
Compounds of Formula I, in which R4 is hydrogen and R5 is any of the definitions of R5 in the Summary of the Invention in which a sulfur atom is attached to the dihydro pyridine ring of Formula I (-SR9 is shown in reaction schemes A and B) can be synthesized according to reaction schemes A or B:
in which R1, R2, R3, and R9 are as described in the Summary of the Invention. In each case, an intermediate is formed by reaction of an aldehyde, a dicarbonyl derivative a base (piperidine or N-methyl morpholine for example) and a thioamide in an alcoholic solvent (e.g., ethanol, or the like). The reaction proceeds for up to about 16 hours in a temperature range from about 5° C. to about 50° C. This intermediate can also be synthesized from the reaction of a more elaborated thioamide and a dicarbonyl compound under the same conditions (scheme B). Alkylation of this intermediate with various alkyl or benzyl halides in the presence of a base (e.g., cesium fluoride, or the like) in a solvent (e.g., ethanol, or the like) in a temperature range from about 5° C. to about 50° C. affords the desired compounds of the Invention.
Compounds prepared from scheme C and D are prepared by mixing a 1,3-dicarbonyl compound with a amino-cyano crotonate derivative and an aldehyde in an alcoholic solvent (e.g., isopropanol, or the like) and optionally in the presence of a base catalyst (e.g., piperidine, or the like). The reactions proceed in a temperature range from about room temperature to about 100° C. for up to about 16 hours. The intermediates A and B are prepared according to scheme E (G. Zhu, and al, J. Org. Chem. 1999, 64, 6907; A. Bhandari and al, Synthesis, 1999, 11, 1951; F. F. Fleming and al, J. Org. Chem., 1997, 62, 3036; D. N. Ridge, and al, J. Med. Chem., 1979 22, 1385).
Specific examples of synthesis of compounds of the invention are detailed in Examples 1 to 3, infra.
A compound of the invention can be prepared as a pharmaceutically acceptable acid addition salt by reacting the free base form of the compound with a pharmaceutically acceptable inorganic or organic acid. Alternatively, a pharmaceutically acceptable base addition salt of a compound of the invention can be prepared by reacting the free acid form of the compound with a pharmaceutically acceptable inorganic or organic base. Alternatively, the salt forms of the compounds of the invention can be prepared using salts of the starting materials or intermediates.
The free acid or free base forms of the compounds of the invention can be prepared from the corresponding base addition salt or acid addition salt from, respectively. For example a compound of the invention in an acid addition salt form can be converted to the corresponding free base by treating with a suitable base (e.g., ammonium hydroxide solution, sodium hydroxide, and the like). A compound of the invention in a base addition salt form can be converted to the corresponding free acid by treating with a suitable acid (e.g., hydrochloric acid, etc.).
Compounds of the invention in unoxidized form can be prepared from N-oxides of compounds of the invention by treating with a reducing agent (e.g., sulfur, sulfur dioxide, triphenyl phosphine, lithium borohydride, sodium borohydride, phosphorus trichloride, tribromide, or the like) in a suitable inert organic solvent (e.g. acetonitrile, ethanol, aqueous dioxane, or the like) at 0 to 80° C.
Prodrug derivatives of the compounds of the invention can be prepared by methods known to those of ordinary skill in the art (e.g., for further details see Saulnier et al., (1994), Bioorganic and Medicinal Chemistry Letters, Vol. 4, p. 1985). For example, appropriate prodrugs can be prepared by reacting a non-derivatized compound of the invention with a suitable carbamylating agent (e.g., 1,1-acyloxyalkylcarbanochloridate, para-nitrophenyl carbonate, or the like).
Protected derivatives of the compounds of the invention can be made by means known to those of ordinary skill in the art. A detailed description of techniques applicable to the creation of protecting groups and their removal can be found in T. W. Greene, “Protecting Groups in Organic Chemistry”, 3rd edition, John Wiley and Sons, Inc., 1999.
Compounds of the present invention can be conveniently prepared, or formed during the process of the invention, as solvates (e.g., hydrates). Hydrates of compounds of the present invention can be conveniently prepared by recrystallization from an aqueous/organic solvent mixture, using organic solvents such as dioxane, tetrahydrofuran or methanol.
Compounds of the invention can be prepared as their individual stereoisomers by reacting a racemic mixture of the compound with an optically active resolving agent to form a pair of diastereoisomeric compounds, separating the diastereomers and recovering the optically pure enantiomers. While resolution of enantiomers can be carried out using covalent diastereomeric derivatives of the compounds of the invention, dissociable complexes are preferred (e.g., crystalline diastereomeric salts). Diastereomers have distinct physical properties (e.g., melting points, boiling points, solubilities, reactivity, etc.) and can be readily separated by taking advantage of these dissimilarities. The diastereomers can be separated by chromatography, or preferably, by separation/resolution techniques based upon differences in solubility. The optically pure enantiomer is then recovered, along with the resolving agent, by any practical means that would not result in racemization. A more detailed description of the techniques applicable to the resolution of stereoisomers of compounds from their racemic mixture can be found in Jean Jacques, Andre Collet, Samuel H. Wilen, “Enantiomers, Racemates and Resolutions”, John Wiley And Sons, Inc., 1981.
In summary, the compounds of Formula I can be made by a process, which involves:
(a) that of reaction schemes A, B, C and D; and
(b) optionally converting a compound of the invention into a pharmaceutically acceptable salt;
(c) optionally converting a salt form of a compound of the invention to a non-salt form;
(d) optionally converting an unoxidized form of a compound of the invention into a pharmaceutically acceptable N-oxide;

The MR antagonist activity of the compounds is determined in a mammalian two hybrid reporter system. The N-terminus of MR (MR-NT, sequence coding amino acid 1-597) is fused to the activation domain of the VP16 gene. The ligand binding domain of MR (MR-LBD, sequence encoding amino acid 672-984) is fused to the DNA binding domain of the yeast Gal4 gene. The MR gene is cloned from a human kidney cDNA library with PCR.
The assay is performed in 384 well plates. Briefly, 293T cells (ATCC) are transfected with expression vectors for Gal4-MR-LBD and VP16-MR NT, and a luciferase reporter vector containing Gal4 binding sequence (pG5-Luc). Cells are plated in 384 well plates immediately after transfection (approximately 3×104 cells/well in 50 μl medium). The medium is supplemented with 3% charcoal-dextran treated fetal bovine serum (Hyclone). Twenty four hours after transfection, compounds prepared in DMSO are transferred to the cells. The cells are then stimulated with 0.4 nM final concentration of aldosterone (Acros) and incubated at 37° C. for another 24 hours before the luciferase activity is assayed with 20 μl of Bright-Glo (Promega) using a luminometer (CLIPR). The expression of luciferase is used as an indicator of aldosterone-induced MR trans-activation. Each compound is tested in duplicate with 12-concentration titration. IC50 values (defined as the concentration of test compound required to antagonize 50% of aldosterone-induced MR activity) are determined from the dose-response curve.
The GR antagonist activity of the compounds is determined in a mammalian two hybrid reporter system. The ligand binding domain of GR (GR-LBD, sequence encoding amino acid 541-778) is fused to the DNA binding domain of the yeast Gal4 gene. The GR gene is cloned from a human lung cDNA library with PCR.
The assay is performed in 384 well plates: COS-7 cells (ATCC) are transfected with expression vectors for Gal-4-GR-LBD and a luciferase reporter vector containing Gal4 binding sequence (pG5-Luc). Cells are plated in 384 well plates immediately after transfection (approximately 8000 cells/well in 50 μl medium). The medium is supplemented with 3% charcoal-dextran treated fetal bovine serum (Hyclone). Twenty four hours after transfection, compounds prepared in DMSO are transferred to the cells. The cells are then stimulated with 10 nM final concentration of dexamethasone (Sigma) and incubated at 37° C. for another 24 hours before the luciferase activity is assayed with 20 μl of Bright-Glo (Promega) using a luminometer (CLIPR). The expression of luciferase is used as an indicator of dexamethasone-induced GR trans-activation. Each compound is tested in duplicate with a 12-concentration titration. IC50 values (defined as the concentration of test compound required to antagonize 50% of dexamethasone-induced GR activity) are determined from the dose-response curve.
The PR antagonist activity of the compounds is determined by progesterone-induced alkaline phosphatase activity in the T-47D cell line (ATCC). In the T-47D breast cancer cells, progesterone specifically induces de novo synthesis of a membrane-associated alkaline phosphatase enzyme in a time and dose-dependent manner (Di Lorenzo et al., Cancer Research, 51: 4470-4475 (1991)). The alkaline phosphatase enzymatic activity can be measured with a chemiluminescent substrate, such as CSPD® (Applied Biosystems).
The assay is performed in 384 well plates. Briefly, T-47D cells are plated in 384 well plates at a density of approximately 2.5×104 cells/well in 50 μl medium supplemented with 10% fetal bovine serum. Twenty four hours later, the medium is aspirated. New medium that is free of phenol red and serum is added to the cells. Compounds prepared in DMSO are transferred to the cells. The cells are then stimulated with 3 nM final concentration of progesterone (Sigma) and incubated at 37° C. for another 24 hours before the alkaline phosphatase is assayed with 25 μl of CSPD® (Applied Biosystems) using a luminometer (CLIPR). The expression of alkaline phosphatase is used as an indicator of progesterone-induced PR trans-activation. Each compound is tested in duplicate with a 12-concentration titration. IC50 values (defined as the concentration of test compound required to antagonize 50% of progesterone-induced PR activity) are determined from the dose-response curve.
The AR antagonist activity of the compounds is determined with the MDA-Kb2 cell line (ATCC), which stably expresses the MMTV luciferase reporter. The MMTV promoter is a mouse mammary tumor virus promoter that contains androgen receptor response elements. The MDA-kb2 cells was derived from the MDA-MB-453 cells, which has been shown to express high levels of functional, endogenous androgen receptor (Wilson et al., Toxicological Sciences, 66: 69-81 (2002)). Upon stimulation with AR ligands, such as dihydrotestosterone, the MMTV luciferase reporter can be activated.
The assay is performed in 384 well plates. Briefly, MDA-kb2 cells are plated in 384 well plates at a density of approximately 2.4×104 cells/well in 50 μl medium. The medium is supplemented with 5% charcoal-dextran treated fetal bovine serum (Hyclone). Twenty four hours later, compounds prepared in DMSO are transferred to the cells. The cells are then stimulated with 0.3 nM final concentration of dihydrotestosterone (Sigma) and incubated at 37° C. for another 24 hours before the luciferase activity is assayed with 20 μl of Bright-Glo (Promega) using a luminometer (CLIPR). The expression of luciferase is used as an indicator of dihydrotestosterone-induced AR trans-activation. Each compound is tested in duplicate with a 12-concentration titration. IC50 values (defined as the concentration of test compound required to antagonize 50% of dihydrotestosterone-induced AR activity) are determined from the dose-response curve.
Competitive binding of the compounds of the invention (test compounds) with a known L-type calcium channel blocker is measured with membrane prepared from rat cortex. 3H-PN-200-100 (150 pM) is incubated together with membrane (50 μg) and test compounds at room temperature for 90 minutes. At the end of the incubation, the reaction mixture is transferred to 96 well filter plates and washed 3 times by flash filtration with ice cold buffer. The plate is dried. The radioactivity is counted in Topcount by liquid scintilation. Non-specific binding is determined in the presence of 1 μM nitrendipine and subtracted from the total binding to obtain the specific binding of test compounds.
The calcium antagonist function of the compounds of the invention (test compounds) is evaluated in the potassium-induced aorta contractility assay at concentrations ranging from 0.1 μM to 10 μM. Briefly, an endothelial denuded aortic ring obtained from Wister-derived rats is placed under 2 g of tension in a 10 ml bath containing Kreb solution (pH 7.4) and 1 μM meclofenamate at 37° C. Any contraction induced by a test compound is recorded isometrically within 5 minutes of the compound addition. If no significant agonist activity is observed, the ability of the test compound to reduce 60 mM KCl-induced contractile response is measured. An inhibition of KCl-induced response by ≧50% indicates antagonist activity.
Compounds of Formula I, in free form or in pharmaceutically acceptable salt form, exhibit valuable pharmacological properties, for example, as indicated by the in vitro tests described in this application (Examples 4-7). The compounds of the invention preferably exhibit inhibitory activity for steroid hormone nuclear receptors and L-type calcium channel with an IC50 in the range of 1×10−9 to 1×10−5M, preferably less than 1 μM, more preferably less than 500 nM. For example:
(i). 2-methylthio-3-cyano-4-(2-bromophenyl)-5-(2-methoxyphenyl)carbamoyl-6-methyl-1,4-dihydro-pyridine (Compound 14) has an IC50 of 8 nM and 2.6 μM for MR and AR, respectively;
(ii). 5-isopropyl-2-methyl-3-cyano-4-(2-bromo-4-fluorophenyl)-6-(methoxymethyl) 1,4-dihydro-pyridine-5-carboxylate (Compound 96) has an IC50 of 9 nM, 39.8 μM, 2.3 μM and 3.1 μM for MR, AR, PR and GR, respectively;
(iii). 5-methyl-2,6-dimethyl-3-cyano-4-(2-chloro-4-fluorophenyl)-1,4-dihydro-pyridine-5-carboxylate (Example 207) has an IC50 of 41 nM for MR 0.478 μM for PR, 2.86 μM for AR, 6.85 μM for GR and 0.24 μM for L-type calcium channel; and
The compounds of the present invention are, therefore, useful for the treatment and/or prevention of diseases in which steroidal nuclear hormone receptor activity and/or L-type calcium channel activity contributes to the pathology and/or symptomatology of the disease.
