Description

P/00/011 Regulation 3.2 Australia Patents Act 1990 ORIGINAL COMPLETE SPECIFICATION STANDARD PATENT Name(s) of Applicant(s): Amgen Inc & Biovitrum AB Title of Invention: 'Inhibitors of 11 -beta-hydroxysteroid dehydrogenase type 1' The following is a full description of this invention, including the best method known to the Applicant(s) of performing the invention: WO 2007/061661 PCT/US2006/043951 INHIBITORS OF 11-BETA-HYDROXY STEROID DEHYDROGENASE TYPE 1 FIELD OF THE INVENTION [00011 This regular U.S. utility application claims priority to United States Provisional Application Serial Number 60/775,975, which was filed on November 22, 2005, and which is incorporated herein by reference in its entirety BACKGROUND OF THE INVENTION [0002] The present invention relates to novel compounds, to pharmaceutical compositions comprising the compounds, as well as to the use of the compounds in medicine and for the preparation of a medicament which acts on the human 11-p hydroxysteroid dehydrogenase type I enzyme (I1IPHSD1). [0003] Hydroxysteroid dehydrogenases (HSDs) regulate the occupancy and activation of steroid hormone receptors by converting steroid hormones into their inactive metabolites. For a recent review, see Nobel at al., Eur. J. Biochem. 2001, 268:41134125. [00041 There exist numerous classes of HSDs. The 1 1-beta-hydroxysteroid dehydrogenases (11 # -HSDs) catalyze the interconversion of active glucocorticoids (such as cortisol and corticosterone), and their inert forms (such as cortisone and 11-. dehydrocorticosterone). The isoform 1 1-beta-hydroxysteroid dehydrogenase type 1 (1 l#5-HSD1) is expressed in liver, adipose tissue, brain, lung and other glucocorticoid tissue and is a potential target for therapy directed at numerous disorders that may be ameliorated by reduction of glucocorticoid action, such as diabetes, obesity and age related cognitive dysfunction. Seckl, et al., Endocrinology, 2001, 142:1371-1376. [00051 The various isozymes of the 17-beta-hydroxysteroid dehydrogenases (17# HSDs) bind to androgen receptors or estrogen receptors and catalyze the interconversion of various sex hormones including estradiol/estrone and testosterone/androstenedione. To date, six isozymes have been identifed in humans and are expressed in various human tissues including endometrial tissue, breast tissue, colon tissue, and in the testes. 17-beta-Hydroxysteroid dehydrogenase type 2 (179 1 WO 2007/061661 PCT/US2006/043951 HSD2) is expressed in human endometrium and its activity has been reported to be linked to cervical cancer. Kitawaki et al., J. Clin. Endocrin. Metab., 2000, 85:1371 3292-3296. 17-beta-Hydroxysteroid dehydrogenase type 3 (17#-HSD3) is expressed in the testes and its modulation may be useful for the treatment of androgen-related disorders. [00061 Androgens and estrogens are active in their 17#-hydroxy configurations, whereas their 17-keto derivatives do not bind to androgen and estrogen receptors and are thus inactive. The conversion between the active and inactive forms (estradiol/estrone and testosterone/androstenedione) of sex hormones is catalyzed by members of the 17#-HSD family. 1716-HSD1 catalyzes the formation of estradiol in breast tissue, which is important for the growth of malignant breast tumors. Labrie et al., Mol. Cell. Endocrinol. 1991, 78:CI 13-C 118. A similar role has been suggested for 170-HSD4 in colon cancer. English et al., J. Clin. Endocrinol. Metab. 1999, 84:2080-2085. 17#-HSD3 is almost exclusively expressed in the testes and converts androstenedione into testosterone. Deficiency of this enzyme during fetal development leads to male pseudohermaphroditism. Geissler et al., Nat. Genet. 1994, 7:34-39. Both 17#-HSD3 and various 3m-HSD isozymes are involved in complex metabolic pathways which lead to androgen shuffles between inactive and active forms. Penning et al., Biochem. J. 2000, 351:67-77. Thus, modulation of certain HSDs can have potentially beneficial effects in the treatment of androgen- and estrogen-related disorders. [0007] The 20-alpha-hydroxysteroid dehydrogenases (20a-HSDs) catalyze the interconversion of progestins (such as between progesterone and 20a-hydroxy progesterone). Other substrates for 20cm-HSDs include 17-hydroxypregnenolone or 17os-hydroxyprogesterone, leading to 20&-OH steroids. Several 20eHSD isoforms have been identified and 20a-HSDs are expressed in various tissues, including the placenta, ovaries, testes and adrenals. Peltoketo, et al., J. Mol. Endocrinol. 1999, 23:1-11. [0008] The 3-alpha-hydroxysteroid dehydrogenases (3a-HSDs) catalyze the interconversion of the androgens dihydrotestosterone (DHT) and Sa-androstane 3 o; 1 70-diol and the interconversion of the androgens DHEA and androstenedione and 2 WO 2007/061661 PCT/US2006/043951 therefore play an important role in androgen metabolism. Ge et al., Biology of Reproduction 1999, 60:855-860. 1. Glucorticolds, diabetes and hepatic glucose production [00091 It has been known for more than half a century that glucocorticoids have a central role in diabetes. For example, the removal of the pituitary gland or the adrenal gland from a diabetic animal alleviates the most severe symptoms of diabetes and lowers the concentration of glucose in the blood (Long, C.D. and Leukins, F.D.W. (1936) J. Exp. Med. 63: 465-490; Houssay, B.A. (1942) Endocrinology 30: 884-892). It is also well established that glucocorticoids enable the effect of glucagon on the liver. [0010] The role of 11p HSD1 as an important regulator of local glucocorticoid effect and thus of hepatic glucose production is well substantiated (see, e.g., Jamieson et al. (2000) J. Endocrinol. 165: 685-692). Hepatic insulin sensitivity was improved in healthy human volunteers treated with the non-specific 11 pHSD I inhibitor carbenoxolone (Walker, B.R. et al. (1995) J. Clin. Endocrinol. Metab. 80: 3155 3159). Furthermore, the expected mechanism has been established by different experiments with mice and rats. These studies showed that the mRNA levels and activities of two key enzymes in hepatic glucose production were reduced, namely: the rate-limiting enzyme in gluconeogenesis, phosphoenolpyruvate carboxykinase (PEPCK), and glucose-6-phosphatase (G6Pase) the enzyme catalyzing the last common step of gluconeogenesis and glycogenolysis. Finally, blood glucose levels and hepatic glucose production are reduced in mice in which the 11 pHSDI gene is knocked-out. Data from this model also confirm that inhibition of 11pHSDI will not cause hypoglycemia, as predicted since the basal levels of PEPCK and G6Pase are regulated independently of glucocorticoids (Kotelevtsev, Y. et al., (1997)-Proc. Nati. Acad. Sci. USA 94: 14924-14929). (0011] FR 2,384,498 discloses compounds having a high hypoglycemic effect. Therefore, treatment of hyperglycemia with these compounds may lead to hypoglycemia. 3 WO 2007/061661 PCT/US2006/043951 2. Reduction of obesity and obesity related cardiovascular risk factors [00121 Obesity is an important factor in syndrome X as well as in the majority (> 80%) of type 2 diabetes, and omental fat appears to be of central importance. Abdominal obesity is closely associated with glucose intolerance, hyperinsulinemia, hypertriglyceridemia, and other factors of the so-called syndrome X (e.g. increased blood pressure, decreased levels of HDL and increased levels of VLDL) (Montague & O'Rahilly, Diabetes 49: 883-888, 2000). Inhibition of the 11pHSD1 enzyme in pre adipocytes (stromal cells) has been shown to decrease the rate of differentiation into adipocytes. This is predicted to result in diminished expansion (possibly reduction) of the omental fat depot, i.e., reduced central obesity (Bujalska, I.J., S. Kumar, and PM. Stewart (1997) Lancet 349: 1210-1213). [0013] Inhibition of 11pHSD1 in mature adipocytes is expected to attenuate secretion of the plasminogen activator inhibitor I (PAI-1) - an independent cardiovascular risk factor (Halleux, C.M. et al. (1999) J. Clin. Endocrinol. Metab. 84: 4097-4105). Furthermore, there is a clear correlation between glucocorticoid "activity" and cardiovascular risk factor suggesting that a reduction of the glucocorticoid effects would be beneficial (Walker, B.R. et al. (1998) Hypertension 31: 891-895; Fraser, R. et al. (1999) Hypertension 33: 1364-1368). [0014] Adrenalectomy attenuates the effect of fasting to increase both food intake and hypothalamic neuropeptide Y expression. This supports the role of glucocorticoids in promoting food intake and suggests that inhibition of 11 PHSD1 in the brain might increase satiety and therefore reduce food intake (Woods, S.C. et al. (1998) Science, 280: 1378-1383). 3. Beneficial effect on the pancreas [0015] Inhibition of 11PHSD1 in isolated murine pancreatic p-cells improves glucose-stimulated insulin secretion (Davani, B. et al. (2000) J. Biol. Chem. 2000 Nov 10; 275(45): 34841-4). Glucocorticoids were previously known to reduce pancreatic insulin release in vivo (Billaudel, B. and B.C.J. Sutter (1979) Horm. Metab. Res. 11: 555-560). Thus, inhibition of 11pHSD1 is predicted to yield other beneficial effects for diabetes treatment, besides the effects on liver and fat. 4 WO 2007/061661 PCT/US2006/043951 4. Beneficial effects on cognition and dementia [0016] Stress and glucocorticoids influence cognitive function (de Quervain, D.J.
F., B. Roozendaal, and J.L. McGaugh (1998) Nature 394: 787-790). The enzyme 11p IHSD 1 controls the level of glucocorticoid action in the brain and thus contributes to neurotoxicity (Rajan, V., C.R.W. Edwards, and J.R Seckl, J. (1996) Neuroscience 16: 65-70; Seckl, J.R., Front. (2000) Neuroendocrinol. 18: 49-99). Unpublished results indicate significant memory improvement in rats treated with a non-specific 1 I pHSDI inhibitor (J. Seckl, personal communication). Based the above and on the known effects of glucocorticoids in the brain, it may also be suggested that inhibiting 11 p HSD1 in the brain may result in reduced anxiety (Tronche, F. et al. (1999) Nature Genetics 23: 99-103). Thus, taken together, the hypothesis is that inhibition of 11p HSD 1 in the human brain would prevent reactivation of cortisone into cortisol and protect against deleterious glucocorticoid-mediated effects on neuronal survival and other aspects of neuronal function, including cognitive impairment, depression, and increased appetite. 5. Use of immuno-modulation using 11PHSD1 inhibitors [0017] The general perception is that glucocorticoids suppress the immune system. But in fact there is a dynamic interaction between the immune system and the HPA (hypothalamo-pituitary-adrenal) axis (Rook, G.A.W. (1999) Baillibr's Clin. Endocrinol. Metab. 13: 576-581). The balance between the-cell-mediated response and humoral responses is modulated by glucocorticoids. A high glucocorticoid activity, such as at a state of stress, is associated with a humoral response. Thus, inhibition of the enzyme I 1pHSD1 has been suggested as a means of shifting the response towards a cell-based reaction. [0018] In certain disease states, including tuberculosis, lepra and psoriasis the immune reaction is normaly biased towards a humoral response when in fact the appropriate response would be cell based. Temporal inhibition of I IHSD1, local or systemic, might be used to push the immune system into the appropriate response (Mason, D. (1991) inmunology Today 12: 57-60; Rook et al., supra). 5 WO 2007/061661 PCT/US2006/043951 [00191 An analogous use of 11 pHSDI inhibition, in this case temporal, would be to booster the immune response in association with immunization to ensure that a cell based response would be obtained, when desired. 6. Reduction of intraocular pressure (0020] Recent data suggest that the levels of the glucocorticoid target receptors and the 11pHSD enzymes determines the susceptibility to glaucoma (Stokes, J. et al. (2000) Invest. Ophthalmol. 41: 1629-1638). Further, inhibition of 11pHSD1 was recently presented as a novel approach to lower the intraocular pressure (Walker E. A. et al, poster P3-698 at the Endocrine society meeting June 12-15, 1999, San Diego). Ingestion of carbenoxolone, a non-specific inhibitor of 11p HSD 1, was shown to reduce the intraocular pressure by 20% in normal subjects. In the eye, expression of 11 PHSD1 is confined to basal cells of the comeal epithelium and the non-pigmented epithelialium of the cornea (the site of aqueous production), to ciliary muscle and to the sphincter and dilator muscles of the iris. In contrast, the distant isoenzyme 11 IHSD2 is highly expressed in the non-pigmented ciliary epithelium and corneal endothelium. None of the enzymes is found at the trabecular meshwork, the site of drainage. Thus, 11 PHSD1 is suggested to have a role in aqueous production, rather than drainage, but it is presently unknown if this is by interfering with activation of the glucocorticoid or the mineralocorticoid receptor, or both. 7. Reduced osteoporosis [00211 Glucocorticoids have an essential role in skeletal development and function but are detrimental in excess. Glucocorticoid-induced bone loss is derived, at least in part, via inhibition of bone formation, which includes suppression of osteoblast proliferation and collagen synthesis (Kim, C.H., Cheng, S.L. and Kim, G.S. (1999) J. Endocrinol. 162: 371-379). The negative effect on bone nodule formation could be blocked by the non-specific inhibitor carbenoxolone suggesting an important role of 11 PHSD1 in the glucocorticoid effect (Bellows, C.G., Ciaccia, A. and Heersche, J.N.M. (1998) Bone 23: 119-125). Other data suggest a role of 11 pHSD1 in providing sufficiently high levels of active glucocorticoid in osteoclasts, and thus in augmenting 6 WO 2007/061661 PCT/US2006/043951 bone resorption (Cooper, M.S. et al. (2000) Bone 27: 375-381). Taken together, these different data suggest that inhibition of I l PHSD1 may have beneficial effects against osteoporosis by more than one mechanism working in parallel. 8. Reduction of hypertension [0022] Bile acids inhibit I lB-hydroxysteroid dehydrogenase type 2. This results in a shift in the overall body balance in favour of cortisol over cortisone, as shown by studying the ratio of the urinary metabolites (Quattropani, C., Vogt, B., Odermatt, A., Dick, B., Frey, B.M., Frey, F.J. (2001) J Clin Invest. Nov;108(9):1299-305. "Reduced activity of I beta-hydroxysteroid dehydrogenase in patients with cholestasis".). Reducing the activity of 11 bHSD1 in the liver by a selective inhibitor is predicted to reverse this imbalance, and acutely counter the symptoms such as hypertension, while awaiting surgical treatment removing the biliary obstruction. [0023] WO 99/65884 discloses carbon substituted aminothiazole inhibitors of cyclin dependent kinases. These compounds may, e.g., be used against cancer, inflammation and arthritis. US 5,856,347 discloses an antibacterial preparation or bactericide comprising 2-aninothiazole derivative and/or salt thereof. Further, US 5,403,857 discloses benzenesulfonamide derivatives having 5-lipoxygenase inhibitory activity. Additionally, tetrahydrothiazolo(5,4-c]pyridines are disclosed in: Analgesic tetrahydrothiazolo[5,4-c]pyridines. Fr. Addn. (1969), 18 pp, Addn. to Fr. 1498465. CODEN: FAXXA3; FR 94123 19690704 CAN 72:100685 AN 1970:100685 CAPLUS and 4,5,6,7-Tetrahydrothiazolo[5,4-c]pyridines. Neth. Appl. (1967), 39 pp. CODEN: NAXXAN NL 6610324 19670124 CAN 68:49593, AN 1968: 49593 CAPLUS. However, none of the above disclosures discloses the compounds according to the present invention, or their use for the treatment of diabetes, obesity, glaucoma, osteoporosis, cognitive disorders, immune disorders, depression, and hypertension. [00241 WO 98/16520 discloses compounds inhibiting matrix metalloproteinases (MMPs) and TNF-a converting enzyme (TACE). EP 0 749 964 Al and US 5,962,490 disclose compounds having an endothelin receptor antagonist activity. WO 00/02851 .discloses compounds associated with a disturbed cOMP balance. None of these 7 WO 2007/061661 PCT/US2006/043951 compounds fall within the present invention. Furthermore, nothing is said about the activity on I IpHSD1. [00251 US 5,783,697 discloses thiophene derivatives as inhibitors of PGE2 and LTB4. Nothing is said about the activity on 11 pHSD 1. {00261 EP 0 558 258, EP 0 569 193. and EP 1 069 114 disclose isoxazole derivatives as endothelin agonists and antagonists. Nothing is said about the activity on 11$HSD1. 9. Wound healing [0027] Cortisol performs a broad range of metabolic functions and other functions. The multitude of glucocorticoid action is exemplified in patients with prolonged increase in plasma glucocorticoids, so called "Cushing's syndrome". Patients with Cushing's syndrome have prolonged increase in plasma glucocorticoids and exhibit impaired glucose tolerance, type 2 diabetes, central obesity, and osteoporosis. These patients also have impaired wound healing and brittle skin (Ganong, W.F. Review of Medical Physiology. Eighteenth edition ed. Stamford, Connecticut: Appleton & Lange; 1997). [0028] Glucocorticoids have been shown to increase risk of infection and delay healing of open wounds (Anstead, G.M. Steroids, retinoids, and wound healing. Adv Wound Care 1998; 11(6):277-85). Patients treated with glucocorticoids have 2-5-fold increased risk of complications when undergoing surgery (Diethelm, A.G. Surgical management of complications of steroid therapy. Ann Surg 1977; 185(3):251-63). [0029] The European patent application No. EP 0902288 discloses a method for diagnosing the status of wound healing in a patient, comprising detecting cortisol levels in said wound. The authors suggest that elevated levels of cortisol in wound fluid, relative to normal plasma levels in healthy individuals, correlates with large, non-healing wounds (Hutchinson, T.C., Swaniker, H.P., Wound diagnosis by quantitating cortisol in wound.fluids. European patent application No. EP 0 902 288, published 17.03.1999). (00301 In humans, the 1 p-HSD catalyzes the conversion of cortisol to cortisone, and vice versa. The parallel function of 11p -HSD in rodents is the interconversion of 8 WO 2007/061661 PCTIUS2006/043951 corticosterone and 11 -dehydrocorticosterone (Frey, F.J., Escher, G., Frey, B.M. Pharmacology of 11 beta-hydroxysteroid dehydrogenase. Steroids 1994;59(2):74-9). Two isoenzymes of 116-HSD, 11 p-HSD1 and I1 f-HSD2, have been characterized, and differ from each other in function and tissue distribution (Albiston, A.L., Obeyesekere, V.R., Smith, R.E., Krozowski, Z.S. Cloning and tissue distribution of the human 11 beta-hydroxysteroid dehydrogenase type 2 enzyme. Mol Cell Endocrinol 1994; 105(2):Rl 1-7). Like GR, 11p -HSD I is expressed in numerous tissues like liver, adipose tissue, adrenal cortex, gonads, lung, pituitary, brain; eye etc (Monder C, White PC. 11 beta-hydroxysteroid dehydrogenase. Vitam Horm 1993;47:187-271; Stewart, P.M., Krozowski, Z.S. 11 beta-Hydroxysteroid dehydrogenase. Vitam Horm 1999;57:249-324; Stokes, J., Noble, J., Brett, L., Phillips, C., Seckil, J.R., O'Brien, C., et al. Distribution of glucocorticoid and mineralocorticoid receptors and 11 beta-hydroxysteroid dehydrogenases in human and rat ocular tissues. Invest Ophthalmol Vis Sci 2000;41(7):1629-38). The function of 11 0-HSD1 is to fine-tune local glucocorticoid action. 1 10-HSD activity has been shown in the skin of humans and rodents, in human fibroblasts and in rat skin pouch tissue (Hammami, M.M., Siiteri, P.K. Regulation of 11 beta-hydroxysteroid dehydrogenase activity in human skin fibroblasts: enzymatic modulation of glucocorticoid action. I Clin Endocrinol Metab 19-9 1;73 (2):326-34); Cooper, M.S., Moore, J., Filer, A., Buckley, C.D., Hewison, M., Stewart, P.M. 11 beta hydroxysteroid dehydrogenase in human fibroblasts: expression and regulation. depends on tissue of origin.

Inhibition of tissue repair by spironolactone: role of mineralocorticoids in fibrous tissue formation. Mol Cell Biochen 1998;189(1-2):47-54). [0031] Wound healing consists of serial events including inflammation, fibroblast proliferation, secretion of ground substances, collagen production, angiogenesis, wound contraction and epithelialization. It can be divided in three phases; inflammatory, proliferative and remodeling phase (reviewed in Anstead et al., supra). 9 WO 2007/061661 PCT/US2006/043951 [00321 In surgical patients, treatment with glucocorticoids increases risk of wound infection and delay healing of open wounds. It has been shown in animal models that restraint stress slows down cutaneous wound healing and increases susceptibility to bacterial infection during wound healing. These effects were reversed by treatment with the glucocorticoid receptor antagonist RU486 (Mercado, A.M., Quan, N., Padgett, D.A., Sheridan, J.F., Marucha, P.T. Restraint stress alters the expression of interleukin- 1 and keratinocyte growth factor at the wound site: an in situ hybridization study. J Neuroiununol 2002;129(1-2):74-83; Rojas, I.G., Padgett, D.A., Sheridan, I.F., Marucha, P.T. Stress-induced susceptibility to bacterial infection during cutaneous wound healing. Brain Behav Imnmun 2002;16(l):74-84). Glucocorticoids produce these effects by suppressing inflammation, decrease wound strength, inhibit wound contracture and delay epithelialization (Anstead et al., supra). Glucocorticoids influence wound healing by interfering with production or action of cytokines and growth factors like IGF, TGF-p, EGF, KGF and PDOF (Beer, H.D., Fassler, R., Werner, S. Glucocorticoid-regulated gene expression during cutaneous wound repair. Vitam Horm 2000;59:217-39; Hamon, G.A., Hunt, T.K., Spencer, E.M.

Proc Natl Acad Sci U S A 1989;86(7):2229-33). It has also been shown that glucocorticoids decrease collagen synthesis in rat and mouse skin in vivo and in rat and human fibroblasts (Oishi, Y., Fu, Z.W., Ohnuki, Y., Kato, H., Noguchi, T.

[01051 The invention will now be described in reference to the following Examples. These Examples are not to be regarded as limiting the scope of the present invention, but shall only serve in an illustrative manner. EXAMPLES BIOLOGICAL EXAMPLES Scintillation Proximity Assay [0106] [1, 2(n) - 3 H]-cortisone *as purchased from Amersham Pharmacia Biotech. Anti-cortisol monoclonal mouse antibody, clone 6D6.7 was obtained from Immunotech and Scintillation proximity assay (SPA) beads coated with monoclonal antimouse antibodies were from Amersham Pharmacia Biotech. NADPH, tetrasodium salt was from CaLbiochen and glucose-6-phosphate (G-6-P) was supplied by Sigma. The human I 1-p-hydroxysteroid dehydrogenase type-l enzyme (1 1-p-HSDI) was expressed in Pichia pastors. 18-p-glycyrrhetinic acid (GA) was obtained from Sigma. The serial dilutions of the compounds were performed on a Tecan Genesis RSP 150. Compounds to be tested were dissolved in DMSO (1 mM) and diluted in 50 mM Tris-HCI, pH 7.2 containing 1 mM EDTA. [0107] The multiplication of plates was done on a WallacQuadra. The amount of the product [ 3 H]-cortisol, bound to the beads was determined in a Packard, Top Count microplate liquid scintillation counter. [0108] The 11 -p-HSDI enzyme assay was carried out in 96 well microtiter plates (Packard, Optiplate) in a total well volume of 220 pL and contained 30 mM Tris-HCI, 65 WO 2007/061661 PCT/US2006/043951 pH 7.2 with 1 mM EDTA, a substrate mixture tritiated Cortisone/NADPH (175 nM / 181 pM), G-6-P (1 mM) and inhibitors in serial dilutions (9 to 0.15 pM). Reactions were initiated by the addition of human 1 1-p-HSDI, either as Pichiapastoris cell homogenate or microsomes prepared from Pichia pastors (the final amount of enzyme used was varied between 0.05 7 to 0.11 mg/mL). Following mixing, the plates were shaken for 30 to 45 minutes at room temperature. The reactions were terminated with 10 pL 1 mM GA stop solution. Monoclonal mouse antibody was then added (10 pL of 4 pM) followed by 100 pL of SPA beads (suspended according to the manufacturers instructions). Appropriate controls were set up by omitting the 11-p
HSD
1 to obtain the non-specific binding (NSB) value. 101091 The plates were covered with plastic film and incubated on a shaker for 30 minutes, at room temperature, before counting. The amount of [ 3 H]-cortisol, bound to the beads was determined in a microplate liquid scintillation counter. The calculation of the K values for the inhibitors was performed by use of Activity Base. The Ki value is calculated from IC 5 o and the Km value is calculated using the Cheng Prushoff equation (with reversible inhibition that follows the Michaelis-Menten equation): K= ICso(l+[S]/Km) [Cheng, Y.C.; Prushoff, W.H. Biochem. Pharmacol. 1973, 22, 3099 3108]. The ICso is measured experimentally in an assay wherein the decrease of the turnover of cortisone to cortisol is dependent on the inhibition potential of each substance. The Ki values of the compounds of the present invention for the 11-0 HSDI enzyme lie typically between about 10 nM and about 10 pM. Below follow some Ki examples according to the present invention. Example Ki value (nM) 10 250 14 107 48 174 Cloning, Expression and Purification of 11P-HSD1 [01101 The expression and purification of the urine enzyme is described by J. Zhang, et al. Biochemistry, 44, 2005, pp 6948-57. The expression and purification of the human enzyme is similar to that of the murine sequence. 66 WO 2007/061661 PCT/US2006/043951 Enzyme Assay: [0111] The IC50 and Ki of the compounds are determined by the following method: 1. Prepare an Assay Buffer, (pH 7.2, 50 mM Tris-HCL, 1 mM EDTA) fresh each week. 2. Prepare the following solutions: NADPH (Sigma, 200 M) 3 H-Cortisone(Amersham Biosciences, 45 Ci/mmol, 200 nM) Enzyme Prep (20 nM for human, 10 nM for mouse) Cortisol Antibody (East Coast Biologicals, (1:50 dilution) Anti-mouse SPA beads (Amersham Biosciences, 15 mg/ml) 18 P-Glycyrrhetinic acid ("GA")(Aldricli, 1 pM) Compound Stock Solution(10mM in DMSO), serially diluted in assay buffer. Each compound is tested at six different concentrations usually (10 )M to 0.1 nM). All of the solutions and dilutions are made in the Assay Buffer. 3. Assay is run using white/white, 96-well assay plates (Coming) in a total volume of 100 gL. 4. Into each well of a 96-well plate is added Assay Buffer (30 IL), compound (10 pL ) NADPH (10 gL), and 3 H-cortisone (10 pL). 5. Initiate reaction by adding 40 pL of HSD-1 enzyme prep to the wells. 6. The plate is covered with tape and incubated on an orbital shaker for 1 h at RT. 7.. After I h, the tape is removed and anti-cortisol antibody (10 PL), GA solution (10 pL), and SPA bead preparation (100 pL) is added. 8. The plate is incubated (30 min) on an orbital shaker at RT. 9. The counts are read on a TopCount NXT reader. 10. A dose-reponse curve is first plotted using the Graphpad Prism software, to generate the IC50 values. [01121 With this IC50 value and the known Km value for the substrate and HSDI enzyme, an estimated Ki can be calculated with the Chen and Prusoff equation {Ki = IC50/ [1+ (substrate/Km)]}. 67 WO 2007/061661 PCT/US2006/043951 [01131 In addition to the above examples, the compounds of the present invention all show 110-HSDl enzyme activity (ICso) in the assays ranging from 10nM and 10 PM.
