The present invention relates to inhibitors of 11β-hydroxy steroid dehydrogenase type 1 (11β-HSD1), pharmaceutical compositions thereof and methods of using the same.
Glucocorticoids, such as cortisol (hydrocortisone), are steroid hormones that regulate fat metabolism, function and distribution, and play a role in carbohydrate, protein and fat metabolism. Glucocorticoids are also known to have physiological effects on development, neurobiology, inflammation, blood pressure, metabolism and programmed cell death. Cortisol and other corticosteroids bind both the glucocorticoid receptor (GR) and the mineralocorticoid receptor (MR), which are members of the nuclear hormone receptor superfamily and have been shown to mediate cortisol function in vivo. These receptors directly modulate transcription via DNA-binding zinc finger domains and transcriptional activation domains.
Until recently, the major determinants of glucocorticoid action were attributed to three primary factors: (1) circulating levels of glucocorticoid (driven primarily by the hypothalamic-pituitary-adrenal (HPA) axis); (2) protein binding of glucocorticoids in circulation; and (3) intracellular receptor density inside target tissues. Recently, a fourth determinant of glucocorticoid function has been identified: tissue-specific pre-receptor metabolism by glucocorticoid-activating and -inactivating enzymes. These 11β-hydroxysteroid dehydrogenase (11β-HSD) pre-receptor control enzymes modulate activation of GR and MR by regulation of glucocorticoid hormones. To date, two distinct isozymes of 11-beta-HSD have been cloned and characterized: 11β-HSD1 (also known as 11-beta-HSD type 1, 11betaHSD1, HSD11B1, and HSD11L) and 11β-HSD2. 11β-HSD1 is a bi-directional oxidoreductase that regenerates active cortisol from inactive 11-keto forms, whereas 11β-HSD2 is a unidirectional dehydrogenase that inactivates biologically active cortisol by converting it into cortisone.
The two isoforms are expressed in a distinct tissue-specific fashion, consistent with the differences in their physiological roles. 11β-HSD1 is widely distributed in rat and human tissues; expression of the enzyme and corresponding mRNA have been detected in human liver, adipose tissue, lung, testis, bone and ciliary epithelium. In adipose tissue, increased cortisol concentrations stimulate adipocyte differentiation and may play a role in promoting visceral obesity. In the eye, 11β-HSD1 may regulate intraocular pressure and may contribute to glaucoma; some data suggests that inhibition of 11β-HSD1 may cause a drop in intraocular pressure in patients with intraocular hypertension (Kotelevtsev, et al., (1997), Proc. Nat'l Acad. Sci. USA 94(26):14924-9). Although 11β-HSD1 catalyzes both 11-beta-dehydrogenation and the reverse 11-oxoreduction reaction, 11β-HSD1 acts predominantly as a NADPH-dependent oxoreductase in intact cells and tissues, catalyzing the formation of active cortisol from inert cortisone (Low, et al., (1994) J. Mol. Endocrin. 13: 167-174). In contrast, 11β-HSD2 expression is found mainly in mineralocorticoid target tissues such as kidney (cortex and medulla), placenta, sigmoid and rectal colon, salivary gland and colonic epithelial cell lines. 11β-HSD2 acts as an NAD-dependent dehydrogenase catalyzing the inactivation of cortisol to cortisone (Albiston, et al., (1994) Mol. Cell. Endocrin. 105: R11-R17), and has been shown to protect the MR from glucocorticoid excess (e.g., high levels of receptor-active cortisol) (Blum, et al., (2003) Prog. Nucl. Acid Res. Mol. Biol. 75:173-216).
Mutations in either the 11β-HSD1 or the 11β-HSD2 genes result in human pathology. For example, individuals with mutations in 11β-HSD2 are deficient in this cortisol-inactivation activity and, as a result, present with a syndrome of apparent mineralocorticoid excess (also referred to as “SAME”) characterized by hypertension, hypokalemia, and sodium retention (Edwards, et al., (1988) Lancet 2: 986-989; Wilson, et al., (1998) Proc. Nat'l Acad. Sci. 95: 10200-10205). Similarly, mutations in 11β-HSD1 and in the gene encoding a co-localized NADPH-generating enzyme, hexose 6-phosphate dehydrogenase (H6PD), can result in cortisone reductase deficiency (CRD); these individuals present with ACTH-mediated androgen excess (hirsutism, menstrual irregularity, hyperandrogenism), a phenotype resembling polycystic ovary syndrome (PCOS) (Draper, et al., (2003) Nat. Genet. 34: 434-439).
Notably, disruption of homeostasis in the HPA axis by either deficient or excess secretion or action results in Cushing's syndrome or Addison's disease, respectively (Miller & Chrousos, Endocrinology and Metabolism (Felig & Frohman eds., McGraw-Hill: New York, 4th Ed. (2001)) 387-524). Patients with Cushing's syndrome or receiving glucocorticoid therapy develop reversible visceral fat obesity. The phenotype of Cushing's syndrome patients closely resembles that of Reaven's metabolic syndrome (also known as Syndrome X or insulin resistance syndrome), the symptoms of which include visceral obesity, glucose intolerance, insulin resistance, hypertension, type 2 diabetes and hyperlipidemia (Reaven, (1993) Ann. Rev. Med. 44, 121-131). Although the role of glucocorticoids in human obesity is not fully characterized, there is mounting evidence that 11β-HSD1 activity plays an important role in obesity and metabolic syndrome (Bujalska, et al., (1997) Lancet 349: 1210-1213); (Livingstone, et al., (2000) Endocrinology 131, 560-563; Rask, et al., (2001) J. Clin. Endocrinol. Metab. 86, 1418-1421; Lindsay, et al., (2003) J. Clin. Endocrinol. Metab. 88: 2738-2744; Wake, et al., (2003) J. Clin. Endocrinol. Metab. 88, 3983-3988).
Data from studies in mouse transgenic models supports the hypothesis that adipocyte 11β-HSD1 activity plays a central role in visceral obesity and metabolic syndrome (Alberts, et al., (2002) Diabetologia. 45(11), 1526-32). Over-expression in adipose tissue of 11β-HSD1 under the control of the aP2 promoter in transgenic mice produced a phenotype remarkably similar to human metabolic syndrome (Masuzaki, et al., (2001) Science 294, 2166-2170; Masuzaki, et al., (2003) J. Clinical Invest. 112, 83-90). Moreover, the increased activity of 11β-HSD1 in these mice is very similar to that observed in human obesity (Rask, et al., (2001) J. Clin. Endocrinol. Metab. 86, 1418-1421). In addition, data from studies with 11βHSD1-deficient mice produced by homologous recombination demonstrate that the loss of 11β-HSD1 leads to an increase in insulin sensitivity and glucose tolerance due to a tissue-specific deficiency in active glucocorticoid levels (Kotelevstev, et al., (1997) Proc. Nat'l Acad. Sci. 94: 14924-14929; Morton, et al., (2001) J. Biol. Chem. 276, 41293-41300; Morton, et al., (2004) Diabetes 53, 931-938),
The published data supports the hypothesis that increased expression of 11β-HSD1 contributes to increased local conversion of cortisone to cortisol in adipose tissue and hence that 11β-HSD1 plays a role in the pathogenesis of central obesity and the appearance of the metabolic syndrome in humans (Engeli, et al., (2004) Obes. Res. 12: 9-17). Therefore, 11β-HSD1 is a promising pharmaceutical target for the treatment of the metabolic syndrome (Masuzaki, et al., (2003) Curr. Drug Targets Immune Endocr. Metabol. Disord. 3: 255-62). Furthermore, inhibition of 11β-HSD1 activity may prove beneficial in treating numerous glucocorticoid-related disorders. For example, 11β-HSD1 inhibitors could be effective in combating obesity and/or other aspects of the metabolic syndrome cluster, including glucose intolerance, insulin resistance, hyperglycemia, hypertension, and/or hyperlipidemia (Kotelevstev, et al., (1997) Proc. Nat'l Acad. Sci. 94, 14924-14929; Morton, et al., (2001) J. Biol. Chem. 276, 41293-41300; Morton, et al., (2004) Diabetes 53, 931-938). In addition, inhibition of 11β-HSD1 activity may have beneficial effects on the pancreas, including the enhancement of glucose-stimulated insulin release (Billaudel & Sutter, (1979) Horm. Metab. Res. 11, 555-560; Ogawa, et al., (1992) J. Clin. Invest. 90, 497-504; Davani, et al., (2000) J. Biol. Chem. 275, 34841-34844). Inter-individual differences in general cognitive function has been linked to variability in the long-term exposure to glucocorticoids (Lupien, et al., (1998) Nat. Neurosci. 1: 69-73) and dysregulation of the HPA axis. Such chronic exposure to glucocorticoid excess in certain brain subregions has been theorized to contribute to the decline of cognitive function (McEwen & Sapolsky (1995) Curr. Opin. Neurobiol. 5, 205-216). Therefore, inhibition of 11β-HSD1 may reduce exposure to glucocorticoids in the brain and thereby protect against deleterious glucocorticoid effects on neuronal function, including cognitive impairment, dementia, and/or depression.
There is also evidence that glucocorticoids and 11β-HSD1 play a role in regulation of in intra-ocular pressure (TOP) (Stokes, et al., (2000) Invest. Ophthalmol. Vis. Sci. 41: 1629-1683; Rauz, et al., (2001) Invest. Ophthalmol. Vis. Sci. 42: 2037-2042). If left untreated, elevated IOP can lead to partial visual field loss and eventually blindness. Thus, inhibition of 11β-HSD1 in the eye could reduce local glucocorticoid concentrations and IOP, and hence could be used to treat or prevent glaucoma and other visual disorders.
Transgenic aP2-11β-HSD1 mice exhibit high arterial blood pressure and have increased sensitivity to dietary salt. Additionally, plasma angiotensinogen levels are elevated in the transgenic mice, as are angiotensin II and aldosterone. Treatment of the mice with an angiotensin II antagonist alleviates the hypertension (Masuzaki, et al., (2003) J. Clinical Invest. 112, 83-90). This suggests that hypertension may be caused or exacerbated by 11β-HSD1 activity. Thus, 11β-HSD1 inhibitors may be useful for treatment of hypertension and hypertension-related cardiovascular disorders.
Glucocorticoids can have adverse effects on skeletal tissues, and prolonged exposure to even moderate glucocorticoid doses can result in osteoporosis (Cannalis, (1996) J. Clin. Endocrinol. Metab. 81, 3441-3447). In addition, 11β-HSD1 has been shown to be present in cultures of human primary osteoblasts as well as cells from adult bone (Cooper, et al., (2000) Bone 27: 375-381), and the 11β-HSD1 inhibitor carbenoxolone has been shown to attenuate the negative effects of glucocorticoids on bone nodule formation (Bellows, et al., (1998) Bone 23: 119-125). Thus, inhibition of 11β-HSD1 is predicted to decrease the local glucocorticoid concentration within osteoblasts and osteoclasts, thereby producing beneficial effects in various forms of bone disease, including osteoporosis.
As evidenced herein, there is a continuing need for new and improved drugs that inhibit 11β-HSD1. The novel compounds of the present invention are effective inhibitors of 11β-HSD1.

The term “ring atom” is an atom such as C, N, O or S that is in the ring of an aryl group, heteroaryl group, cycloalkyl group or heterocyclic group. A “substitutable ring atom” in an aryl, heteroaryl cycloalkyl or heterocyclic is a carbon or nitrogen atom in the aryl, heteroaryl, cycloalkyl or heterocyclic group that is bonded to at least one hydrogen atom. The hydrogen(s) can be optionally replaced with a suitable substituent group. Thus, the term “substitutable ring atom” does not include ring carbon or nitrogen atoms when the structure depicts that they are not attached to any hydrogen atoms.

The compounds of the invention may be present in the form of pharmaceutically acceptable salts. For use in medicines, the salts of the compounds of the invention refer to non-toxic “pharmaceutically acceptable salts.” Pharmaceutically acceptable salt forms include pharmaceutically acceptable acidic/anionic or basic/cationic salts.
Pharmaceutically acceptable acidic/anionic salts include, the acetate, benzenesulfonate, benzoate, bicarbonate, bitartrate, bromide, calcium edetate, camsylate, carbonate, chloride, citrate, dihydrochloride, edetate, edisylate, estolate, esylate, fumarate, glyceptate, gluconate, glutamate, glycollylarsanilate, hexylresorcinate, hydrobromide, hydrochloride, hydroxynaphthoate, iodide, isethionate, lactate, lactobionate, malate, maleate, mandelate, mesylate, methylsulfate, mucate, napsylate, nitrate, pamoate, pantothenate, phosphate/diphospate, polygalacturonate, salicylate, stearate, subacetate, succinate, sulfate, tannate, tartrate, teoclate, tosylate, and triethiodide salts.

Salts of the disclosed 11β-HSD1 inhibitors containing an acidic functional group can be prepared by reacting with a suitable base. Such a pharmaceutically acceptable salt may be made with a base which affords a pharmaceutically acceptable cation, which includes alkali metal salts (especially sodium and potassium), alkaline earth metal salts (especially calcium and magnesium), aluminum salts and ammonium salts, as well as salts made from physiologically acceptable organic bases such as trimethylamine, triethylamine, morpholine, pyridine, piperidine, picoline, dicyclohexylamine, N,N′-dibenzylethylenediamine, 2-hydroxyethylamine, bis-(2-hydroxyethyl)amine, tri-(2-hydroxyethyl)amine, procaine, dibenzylpiperidine, dehydroabietylamine, N,N′-bisdehydroabietylamine, glucamine, N-methylglucamine, collidine, quinine, quinoline, and basic amino acids such as lysine and arginine.
The invention also includes various isomers and mixtures thereof. “Isomer” refers to compounds that have the same composition and molecular weight but differ in physical and/or chemical properties. The structural difference may be in constitution (geometric isomers) or in the ability to rotate the plane of polarized light (stereoisomers).
Certain of the disclosed 11β-HSD1 inhibitors may exist in various stereoisomeric forms. Stereoisomers are compounds that differ only in their spatial arrangement. Enantiomers are pairs of stereoisomers whose mirror images are not superimposable, most commonly because they contain an asymmetrically substituted carbon atom that acts as a chiral center. “Enantiomer” means one of a pair of molecules that are mirror images of each other and are not superimposable. Diastereomers are stereoisomers that are not related as mirror images, most commonly because they contain two or more asymmetrically substituted carbon atoms. The symbol “*” in a structural formula represents the presence of a chiral carbon center. “R” and “S” represent the configuration of substituents around one or more chiral carbon atoms. Thus, “R*” and “S*” denote the relative configurations of substituents around one or more chiral carbon atoms. When a chiral center is not defined as R or S, a mixture of both configurations is present.
“Racemate” or “racemic mixture” means a compound of equimolar quantities of two enantiomers, wherein such mixtures exhibit no optical activity; i.e., they do not rotate the plane of polarized light.
“Geometric isomer” means isomers that differ in the orientation of substituent atoms in relationship to a carbon-carbon double bond, to a cycloalkyl ring, or to a bridged bicyclic system. Atoms (other than H) on each side of a carbon-carbon double bond may be in an E (substituents are on opposite sides of the carbon-carbon double bond) or Z (substituents are oriented on the same side) configuration.
The compounds of the invention may be prepared as individual isomers by either isomer-specific synthesis or resolved from an isomeric mixture. Conventional resolution techniques include forming the salt of a free base of each isomer of an isomeric pair using an optically active acid (followed by fractional crystallization and regeneration of the free base), forming the salt of the acid form of each isomer of an isomeric pair using an optically active amine (followed by fractional crystallization and regeneration of the free acid), forming an ester or amide of each of the isomers of an isomeric pair using an optically pure acid, amine or alcohol (followed by chromatographic separation and removal of the chiral auxiliary), or resolving an isomeric mixture of either a starting material or a final product using various well known chromatographic methods.
When a disclosed compound is named or depicted by structure without indicating the stereochemistry, and the compound has at least one chiral center, it is to be understood that the name or structure encompasses one enantiomer of inhibitor free from the corresponding optical isomer, a racemic mixture of the inhibitor and mixtures enriched in one enantiomer relative to its corresponding optical isomer. When the stereochemistry of a disclosed compound is named or depicted by structure, the named or depicted stereoisomer is at least 60%, 70%, 80%, 90%, 95%, 98%, 99% or 99.9% by weight pure relative to the other stereoisomers. When a single enantiomer is named or depicted by structure, the depicted or named enantiomer is at least 60%, 70%, 80%, 90%, 95%, 98%, 99% or 99.9% by weight optically pure. Percent optical purity by weight is the ratio of the weight of the enantiomer over the weight of the enantiomer plus the weight of its optical isomer. When a single geometric isomer, e.g., a geometric isomer with a double bond, is depicted by name or structure and the stereochemistry about the double is indicated, the compound is considered to be at least 60%, 70%, 80%, 90%, 95%, 98%, 99% or 99.9% steroechemically pure by weight. Percent stereochemically purity by weight is the ratio of the weight of the geometric isomer over the weight of the both geometric isomers. For example, 99% stereochemically pure means that at least 99% by weight of the compound is the indicated stereoisomer.
A pharmaceutical composition of the invention may, alternatively or in addition to a compound of Formulae I and Ia-Ig, comprise a pharmaceutically acceptable salt of a compound of Formulae I and Ia-Ig, or a prodrug or pharmaceutically active metabolite of such a compound or salt and one or more pharmaceutically acceptable carriers therefor.
“Effective amount” means that amount of active compound agent that elicits the desired biological response in a subject. Such response includes alleviation of the symptoms of the disease or disorder being treated. The effective amount of a compound of the invention in such a therapeutic method is from about 0.01 mg/kg/day to about 10 mg/kg/day, preferably from about 0.5 mg/kg/day to 5 mg/kg/day.
“Inhibiting 11β-HSD1” means to decrease the activity of the 11β-HSD1 enzyme.
“Modulating 11β-HSD1” means to impact the activity of the 11β-HSD1 enzyme by altering its natural activity. Modulation can be analogous to inhibition when a disease or disorder relating to the activity 11β-HSD1 would be effectively treated by suppressing the activity of the enzyme.
“Pharmaceutically acceptable carrier” means compounds and compositions that are of sufficient purity and quality for use in the formulation of a composition of the invention and that, when appropriately administered to an animal or human, do not produce an adverse reaction.
“Treatment” or “treating”, as used herein, includes prophylactic and therapeutic treatment. “Therapeutic treatment” includes partially or totally inhibiting, delaying, or reducing the severity of the disease or disorder related to 11β-HSD1. “Prophylactic treatment” encompasses administration of a compound of the invention to a subject susceptible to a disease or disorder related to the activity or expression of 11β-HSD1 in an effort to reduce the likelihood of a subject developing the disease or disorder, or slowing or preventing progression of the disease. Prophylactic treatment includes suppression (partially or completely) of the disease or disorder, and further includes reducing the severity of the disease or disorder, if onset occurs. Prophylactic treatment is particularly advantageous for administration to mammals at risk for developing a disease or disorder related to 11β-HSD1.
The compounds of the present invention can be prepared and administered in a wide variety of oral and parenteral dosage forms. Thus, the compounds of the present invention can be administered by injection, that is, intravenously, intramuscularly, intracutaneously, subcutaneously, intraduodenally, or intraperitoneally. Additionally, the compounds of the present invention can be administered intranasally or transdermally.
It will be obvious to those skilled in the art that the following dosage forms may comprise as the active ingredient, either compounds or a corresponding pharmaceutically acceptable salt of a compound of the present invention.
For preparing pharmaceutical compositions from the compounds of the present invention, pharmaceutically acceptable carriers can either be solid or liquid. Solid form preparations include powders, tablets, pills, capsules, cachets, suppositories, and dispersable granules. A solid carrier can be one or more substances which may also act as diluents, flavoring agents, solubilizers, lubricants, suspending agents, binders, preservatives, tablet disintegrating agents, or an encapsulating material. In powders, the carrier is a finely divided solid which is in a mixture with the finely divided active ingredient.
In tablets, the active ingredient is mixed with the carrier having the necessary binding properties in suitable proportions and compacted in the shape and size desired.

Suitable carriers are magnesium, carbonate, magnesium stearate, talc, sugar, lactose, pectin, dextrin, starch, gelatin, tragacanth, methylcellulose, sodium carboxymethylcelluose, a low melting wax, cocoa butter, and the like. Tablets, powders, cachets, lozenges, fast-melt strips, capsules and pills can be used as solid dosage forms containing the active ingredient suitable for oral administration. For preparing suppositories, a low melting wax, such as a mixture of fatty acid glycerides or cocoa butter, is first melted and the active ingredient is dispersed homogeneously therein, as by stirring. The molten homogeneous mixture is then poured into convenient sized molds, allowed to cool, and thereby to solidify.
Liquid form preparations include solutions, suspensions, retention enemas, and emulsions, for example, water or water propylene glycol solutions. For parenteral injection, liquid preparations can be formulated in solution in aqueous polyethylene glycol solution.
Aqueous solutions suitable for oral administration can be prepared by dissolving the active ingredient in water and adding suitable colorants, flavors, stabilizing, and thickening agents as desired. Aqueous suspensions for oral administration can be prepared by dispersing the finely divided active ingredient in water with viscous material, such as natural or synthetic gums, resins, methylcellulose, sodium carboxymethyl cellulose, and other well-known suspending agents.
The pharmaceutical composition is preferably in unit dosage form. In such form, the composition is subdivided into unit doses containing appropriate quantities of the active ingredient. The unit dosage form can be a packaged preparation, the package containing discrete quantities of, for example, tablets, powders, and capsules in vials or ampules. Also, the unit dosage form can be a tablet, cachet, capsule, or lozenge itself, or it can be the appropriate amount of any of these in packaged form.
The quantity of active ingredient in a unit dose preparation may be varied or adjusted from about 0.1 mg to about 1000.0 mg, preferably from about 0.1 mg to about 100 mg. The dosages, however, may be varied depending upon the requirements of the patient, the severity of the condition being treated, and the compound being employed. Determination of the proper dosage for a particular situation is within the skill in the art. Also, the pharmaceutical composition may contain, if desired, other compatible therapeutic agents.
In therapeutic treatment or as a method-of-use as an inhibitor of 11β-HSD1 or an inhibitor in the production of cortisol in the cell, the active ingredient is preferably administered orally in a solid dosage form as disclosed above in an amount of about 0.1 mg to about 100 mg per daily dose where the dose is administered once or more than once daily.

The following abbreviations have the indicated meanings:
Compounds of Formula I can be prepared by several processes. In the discussion below, A1, A2, Cy1, Cy2, E, Q, R1, R2, R3, R5, Y, and n have the meanings indicated above unless otherwise noted. In cases where the synthetic intermediates and final products of Formula I described below contain potentially reactive functional groups, for example amino, hydroxyl, thiol and carboxylic acid groups, that may interfere with the desired reaction, it may be advantageous to employ protected forms of the intermediate. Methods for the selection, introduction and subsequent removal of protecting groups are well known to those skilled in the art. (T. W. Greene and P. G. M. Wuts “Protective Groups in Organic Synthesis” John Wiley & Sons, Inc., New York 1999). Such protecting group manipulations are assumed in the discussion below and not described explicitly. Generally, reagents in the reaction schemes are used in equimolar amounts; however, in certain cases it may be desirable to use an excess of one reagent to drive a reaction to completion. This is especially the case when the excess reagent can be readily removed by evaporation or extraction. Bases employed to neutralize HCl in reaction mixtures are generally used in slight to substantial excess (1.05-5 equivalents).
In a first process, compounds of Formula I can be prepared by reaction of intermediates of Formula II with reagents of Formula III, wherein Z1 and Z2 are leaving groups such as chloride, 1-imidazolyl or aryloxide, in an inert solvent such as THF, CH2Cl2, toluene or MeCN, usually in the presence of an organic or inorganic base such as triethylamine or NaHCO3 respectively, at −10° C. to 120° C.:
Certain instances of reagent III are especially convenient because they are commercially available. For example when Z1 and Z2 are both chloride, III is phosgene. When Z1 and Z2 are both 1-imidazolyl, III is carbonyl diimidazole. When Z1 is chloride and Z2 is p-nitrophenoxide, III is p-nitrophenyl chloroformate. When Z1 and Z2 are both OCCl3, III is triphosgene and as little as one third of molar equivalent can be used.

Pre-adipocytes were differentiated by the addition of insulin, dexamethasone, indomethacin and isobutyl-methylxanthine (supplied by Lonza) to the Preadipocyte Growth Medium-2. Cells were exposed to the differentiating factors for 7 days, at which point the cells were differentiated and ready for the assay. One day before running the assay, the differentiated omental adipocytes were transferred into serum- and phenol-red-free medium for overnight incubation. The assay was performed in a total volume of 200 μL. The cells were pre-incubated with serum-free, phenol-red-free medium containing 0.1% (v/v) of DMSO and various concentrations of the test compounds at least 1 h before [3H] cortisone in ethanol (50 Ci/mmol, ARC, Inc.) was added to achieve a final concentration of cortisone of 100 nM. The cells were incubated for 3-4 hrs at 37° C., 5% CO2. Negative controls were incubated without radioactive substrate and received the same amount of [3H] cortisone at the end of the incubation. Formation of [3H] cortisol was monitored by analyzing 25 μL of each supernatant in a scintillation proximity assay (SPA). (Solly, K.; Mundt, S. S.; Zokian, H. J.; Ding, G. J.; Hermanowski-Vosatka, A.; Strulovici, B.; Zheng, W. Assay Drug Dev. Technol. 2005, 3, 377-384). Many compounds of the invention showed significant activity in this assay.
a++ means IC50 = <100 nM, + means IC50 = 100-1000 nM, # means IC50 > 100 nM, nt means not tested.
