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-β-hydroxysteroid dehydrogenase type 1 enzyme (11βHSD1).
1. Glucorticoids, Diabetes and Hepatic Glucose Production
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.
The role of 11βHSD1 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 11βHSD1 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 11βHSD1 gene is knocked-out. Data from this model also confirm that inhibition of 11βHSD1 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. Natl. Acad. Sci. USA 94: 14924-14929).
2. Possible Reduction of Obesity and Obesity Related Cardiovascular Risk Factors
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 11βHSD1 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 P. M. Stewart (1997) Lancet 349: 1210-1213).
Inhibition of 11βHSD1 in mature adipocytes is expected to attenuate secretion of the plasminogen activator inhibitor 1 (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).
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 11βHSD1 in the brain might increase satiety and therefore reduce food intake (Woods, S. C. et al. (1998) Science, 280: 1378-1383).
3. Possible Beneficial Effect on the Pancreas
Inhibition of 11βHSD1 in isolated murine pancreatic β-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 11βHSD1 is predicted to yield other beneficial effects for diabetes treatment, besides the effects on liver and fat.
4. Possible Beneficial Effects on Cognition and Dementia
Stress and glucocorticoids influence cognitive function (de Quervain, D. J.-F., B. Roozendaal, and J. L. McGaugh (1998) Nature 394: 787-790). The enzyme 11βHSD1 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 11βHSD1 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 11βHSD1 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 11βHSD1 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. Possible Use of Immuno-Modulation using 11βHSD1 Inhibitors
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) Baillièr'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 11βHSD1 has been suggested as a means of shifting the response towards a cell-based reaction.
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 11βHSD1, local or systemic, might be used to push the immune system into the appropriate response (Mason, D. (1991) Immunology Today 12: 57-60; Rook et al., supra).
An analogous use of 11βHSD1 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
Recent data suggest that the levels of the glucocorticoid target receptors and the 11βHSD enzymes determines the susceptibility to glaucoma (Stokes, J. et al. (2000) Invest. Ophthalmol. 41: 1629-1638). Further, inhibition of 11βHSD1 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 Jun. 12-15, 1999, San Diego). Ingestion of carbenoxolone, a non-specific inhibitor of 11βHSD1, was shown to reduce the intraocular pressure by 20% in normal subjects. In the eye, expression of 11βHSD1 is confined to basal cells of the corneal 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 11βHSD2 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, 11βHSD1 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
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 11βHSD1 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 11βHSD1 in providing sufficiently high levels of active glucocorticoid in osteoclasts, and thus in augmenting bone resorption (Cooper, M. S. et al. (2000) Bone 27: 375-381). Taken together, these different data suggest that inhibition of 11βHSD1 may have beneficial effects against osteoporosis by more than one mechanism working in parallel.
8. Reduction of Hypertension
Bile acids inhibit 11β-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. November;108(9):1299-305. “Reduced activity of 11beta-hydroxysteroid dehydrogenase in patients with cholestasis”.). Reducing the activity of 11βHSD1 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.
9. Wound Healing
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, Conn.: Appleton & Lange; 1997).
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).
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, Mar. 1999).
In humans, the 11βHSD catalyzes the conversion of cortisol to cortisone, and vice versa. The parallel function of 11βHSD in rodents is the interconversion of corticosterone and 11-dehydrocorticosterone (Frey F. J., Escher, G., Frey, B. M. Pharmacology of 11 beta-hydroxysteroid dehydrogenase. Steroids 1994;59(2):74-9). The ratio of total cortisone to cortisol in human plasma is 0.2 in adults. However, the concentration of free cortisol and cortisone are almost equal, since most cortisol, but very little cortisone is protein bound. Cortisone thus functions as a large precursor pool for active glucocorticoids (Hammami, M. M, Siiteri, P. K. Regulation of 11 beta-hydroxysteroid dehydrogenase activity in human skin fibroblasts: enzymatic modulation of glucocorticoid action. J Clin Endocrinol Metab 1991;73(2):326-34). Two isoenzymes of 11βHSD, 11βHSD1 and 11βHSD2, 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):R11-7).
Mineralocorticoid receptors (MR) have similar affinity for cortisol and aldosterone, the active mineralocorticoid and circulating levels of glucocorticoids are substantially higher than levels of mineralocorticoids. Thus, for selectivity of mineralocorticoids in mineralocorticoid-target tissues, an additional mechanism must operate. This paradox led to the finding of the physiological role of 11βHSD2 in kidneys and other mineralocorticoid tissues. 11βHSD2 catalyses the inactivation of cortisol to cortisone, and thereby protects MR from circulating glucocorticoids and confers specificity of aldosterone for MR (Funder, J. W., Pearce, P. T., Smith, R., Smith, A. I. Mineralocorticoid action: target tissue specificity is enzyme, not receptor, mediated. Science 1988;242(4878):583-5). 11βHSD2 is expressed in kidney, salivary glands, placenta, ileum, distal colon and epithelia of respiratory tract, where it is co-localized with MR (Hirasawa, G., Sasano, H., Takahashi, K., Fukushima, K., Suzuki, T., Hiwatashi, N., et al. Colocalization of 11 beta-hydroxysteroid dehydrogenase type II and mineralocorticoid receptor in human epithelia. J Clin Endocrinol Metab 1997;82(11):3859-63; Krozowski, Z., MaGuire, J. A., Stein-Oakley, A. N., Dowling, J., Smith, R. E., Andrews, R,K. Immunohistochemical localization of the 11 beta-hydroxysteroid dehydrogenase type II enzyme in human kidney and placenta. J Clin Endocrinol Metab 1995;80(7):2203-9).
In vitro 11β-HSD1 has the capacity to act both as oxidase and reductase, but in vivo it mainly functions as a reductase, i.e. converting cortisone to cortisol and thereby locally increase glucocorticoid action. In contrast to 11β-HSD2 which uses NAD as co-factor, 11β-HSD1 is NADP dependent (Mercer W R, Krozowski Z S. Localization of an 11 beta hydroxysteroid dehydrogenase activity to the distal nephron. Evidence for the existence of two species of dehydrogenase in the rat kidney. Endocrinology 1992; 130(1):540-3). Like GR, 11β-HSD1 is expressed in numerous tissues like liver, adipose tissue, adrenal cortex, gonads, lung, pituitary, brain, eye etc (Monder C, White P C. 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, Seckl J R, O'Brien C, et al. Distribution of glucocorticoid and mineralocorticoid receptors and 11beta-hydroxysteroid dehydrogenases in human and rat ocular tissues. Invest Ophthalmol Vis Sci 2000;41(7): 1629-38). The function of 11β-HSD1 is to fine-tune local glucocorticoid action. It acts to amplify glucocorticoid action in certain cells to maintain basal metabolic function during for example the diurnal nadir of glucocorticoid secretion. 11β-HSD activity has been shown in the skin of humans and rodents, in human fibroblasts and in rat skin pouch tissue (Hammami et al., supra; Cooper M S, Moore J, Filer A, Buckley C D, Hewison M, Stewart P M. 11beta-hydroxysteroid dehydrogenase in human fibroblasts: expression and regulation depends on tissue of origin. ENDO 2003 Abstracts 2003; Teelucksingh S, Mackie A D, Burt D, McIntyre M A, Brett L, Edwards CR. Potentiation of hydrocortisone activity in skin by glycyrrhetinic acid. Lancet 1990;335(8697):1060-3; Slight S H, Chilakamarri V K, Nasr S, Dhalla A K, Ramires F J, Sun Y, et al. Inhibition of tissue repair by spironolactone: role of mineralocorticoids in fibrous tissue formation. Mol Cell Biochem 1998; 189(1-2):47-54).
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).
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 Neuroimmunol 2002;129(1-2):74-83; Rojas, I. G., Padgett, D. A., Sheridan, J. F., Marucha, P. T. Stress-induced susceptibility to bacterial infection during cutaneous wound healing. Brain Behav Immun 2002;16(1):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-β, EGF, KGF and PDGF (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. In vivo effects of systemic insulin-like growth factor-I alone and complexed with insulin-like growth factor binding protein-3 on corticosteroid suppressed wounds. Growth Regul 1993;3(1):53-6; Laato, M., Heino, J., Kahari, V. M., Niinikoski, J., Gerdin, B. Epidermal growth factor (EGF) prevents methylprednisolone-induced inhibition of wound healing.

Transforming growth factor beta reverses the glucocorticoid-induced wound-healing deficit in rats: possible regulation in macrophages by platelet-derived growth factor. 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. Molecular basis of the alteration in skin collagen metabolism in response to in vivo dexamethasone treatment: effects on the synthesis of collagen type I and III, collagenase, and tissue inhibitors of metalloproteinases. Br J Dermatol 2002;147(5):859-68).

Larock, Comprehensive Organic Transformations, VCH Publishers (1989); T. W. Greene and P. G. M. Wuts, Protective Groups in Organic Synthesis, 3rd Ed., John Wiley and Sons (1999); L. Fieser and M. Fieser, Fieser and Fieser's Reagents for Organic Synthesis, John Wiley and Sons (1994); and L. Paquette, ed., Encyclopedia of Reagents for Organic Synthesis, John Wiley and Sons (1995) and subsequent editions thereof.
All publications mentioned herein are hereby incorporated by reference. By the expression “comprising” means “including but not limited to.” Thus, other non-mentioned substances, additives or carriers may be present.
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.
Scintillation Proximity Assay
[1,2(n)-3H]-cortisone was 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 Calbiochem and glucose-6-phosphate (G-6-P) was supplied by Sigma. The human 11-β-hydroxysteroid dehydrogenase type-1 enzyme (11-β-HSD1) was expressed in Pichia pastoris. 18-β-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-HCl, pH 7.2 containing 1 mM EDTA.
The multiplication of plates was done on a WallacQuadra. The amount of the product [3H]-cortisol, bound to the beads was determined in a Packard, Top Count microplate liquid scintillation counter.
The 11-β-HSD1 enzyme assay was carried out in 96 well microtiter plates (Packard, Optiplate) in a total well volume of 220 μL and contained 30 mM Tris-HCl, pH 7.2 with 1 mM EDTA, a substrate mixture tritiated Cortisone/NADPH (175 nM/181 μM), G-6-P (1 mM) and inhibitors in serial dilutions (9 to 0.15 μM). Reactions were initiated by the addition of human 11-β-HSD1, either as Pichia pastoris cell homogenate or microsomes prepared from Pichia pastoris (the final amount of enzyme used was varied between 0.057 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 μL 1 mM GA stop solution. Monoclonal mouse antibody was then added (10 μL of 4 μM) followed by 100 μL of SPA beads (suspended according to the manufacturers instructions). Appropriate controls were set up by omitting the 11-β-HSD1 to obtain the non-specific binding (NSB) value.
The plates were covered with plastic film and incubated on a shaker for 30 minutes, at room temperature, before counting. The amount of [3H]-cortisol, bound to the beads was determined in a microplate liquid scintillation counter. The calculation of the Ki values for the inhibitors was performed by use of Activity Base. The Ki value is calculated from IC50 and the Km value is calculated using the Cheng Prushoff equation (with reversible inhibition that follows the Michaelis-Menten equation): Ki=IC50(1+[S]/Km) [Cheng, Y. C.; Prushoff, W. H. Biochem. Pharmacol. 1973, 22, 3099-3108]. The IC50 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-β-HSD1 enzyme lie typically between about 10 nM and about 10 μM. Illustrative Ki values for some Examples according to the present invention are given below.
All commercial starting materials are used without any purification.
If the appropriate a-bromo carboxylic acid or ester not is commercially availiable, the substances has been prepared in accordance to this method:
The 2-amino-carboxylic acid (1.0 eq.) was suspended in 2.0 M H2SO4 (4 eq.), KBr (8 eq.) was added and the mixture was cooled in an ice-bath. NaNO2 (1.3 eq.) dissolved in water was added slowly. The reaction mixture was stirred for 4 h at ice-bath, before allowed to reach room temperature. The reaction mixture was extracted with EtOAc. The organic phase was dried over MgSO4 before concentrated in vacuum. This gave the crude product which was used in the next step without further purification (J. Org. Chem. 2002, 67 (11), 3595-3600; Xinhua Qian; Bin Zheng; Brian Burke; Manohar T. Saindane and David R. Kronenthal).
