Definitions

• the present invention relates to inhibitors of 11 ⁇ -hydroxysteroid dehydrogenase type 1 (11 ⁇ -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.
• Cortisol hydrocortisone
• glucocorticoid action was 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.
• HPA hypothalamic-pituitary-adrenal
• glucocorticoid function has been identified: tissue-specific pre- receptor metabolism by glucocorticoid-activating and -inactivating enzymes.
• 11 ⁇ -hydroxysteroid dehydrogenase pre-receptor control enzymes modulate activation of GR and MR by regulation of glucocorticoid hormones.
• 11 ⁇ -HSD1 also known as 11-beta-HSD type 1 , 11 betaHSD1 , HSD11 B1 , HDL
• 11 ⁇ -HSD1 also known as 1 1-beta-HSD type 1 , 11 betaHSD1 , HSD11 B1 , HDL, and HSD11 L
• 1 1 ⁇ -HSD2 1 1 ⁇ -HSD2.
• 1 1 ⁇ -HSD1 is a bi-directional oxidoreductase that regenerates active Cortisol from inactive 11-keto forms
• 1 1 ⁇ -HSD2 is a unidirectional dehydrogenase that inactivates biologically active Cortisol by converting it into cortisone.
• 11 ⁇ -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, 11 ⁇ -HSD1 may regulate intraocular pressure and may contribute to glaucoma; some data suggest that inhibition of 11 ⁇ -HSD1 may cause a drop in intraocular pressure in patients with intraocular hypertension (Kotelevstev et al.
• 11 ⁇ -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.
• 11 ⁇ -HSD2 acts as an NAD-dependent dehydrogenase catalyzing the inactivation of Cortisol to cortisone (Albiston et al. (1994) MoI. 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. MoI. Biol. 75:173- 216).
• Mutations in either the 11 ⁇ -HSD1 or the 11 ⁇ -HSD2 genes result in human pathology.
• individuals with mutations in 11 ⁇ -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. Natl. Acad. Sci. 95: 10200-10205).
• H6PD cortisone reductase deficiency
• PCOS polycystic ovary syndrome
• 11 ⁇ -HSD1 inhibitors could be effective in combating obesity and/or aspects of the metabolic syndrome cluster, including glucose intolerance, insulin resistance, hyperglycemia, hypertension, and/or hyperlipidemia (Kotelevstev et al. (1997) Proc. Natl. Acad. Sci. 94: 14924-14929; Morton et al. (2001) J. Biol. Chem. 276: 41293-41300; Morton et al. (2004) Diabetes 53: 931-938).
• inhibition of 11 ⁇ -HSD1 activity may have beneficial effects on the pancreas, including the enhancement of glucose-stimulated insulin release (Billaudel and 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).
• Transgenic aP2-11 ⁇ HSD1 mice exhibit high arterial blood pressure and have increased sensitivity to dietary salt. Moreover, plasma angiotensinogen levels are elevated in the transgenic mice, as are angiotensin Il and aldosterone; and treatment of the mice with an angiotensin Il antagonist alleviates the hypertension (Masuzaki et al. (2003) J. Clinical Invest. 112: 83-90). This suggests that hypertension may be caused or exacerbated by 11 ⁇ -HSD1 activity. Thus, 1 1 ⁇ -HSD1 inhibitors may be useful for treatment of hypertension and hypertension-related cardiovascular disorders.
• Inhibition of 11 ⁇ -HSD1 in mature adipocytes is also expected to attenuate secretion of plasminogen activator inhibitor 1 (PAI-1 ), which is an independent cardiovascular risk factor (Halleux et al. (1999) J. Clin. Endocrinol. Metabl. 84: 4097- 4105).
• PAI-1 plasminogen activator inhibitor 1
• 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).
• 11 ⁇ -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 11 ⁇ -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).
• 11 ⁇ -HSD1 inhibitors may also be useful for immunomodulation.
• glucocorticoids are perceived to suppress the immune system, in actuality, there is a complex, dynamic interaction between the HPA axis and the immune system (Rook (1999) Baillier's Clin. Endocrinol. Metabl. 13: 576-581 ).
• Glucocorticoids play a role in modulating the balance between cell-mediated and humoral immune response, with high glucocorticoid activity normally associated with a humoral response. Inhibition of 11 ⁇ -HSD1 therefore can be used a means of shifting the immune response towards a cell-mediated response.
• Certain disease states such as tuberculosis, leprosy (Hansen's disease) and psoriasis, trigger immune responses that are biased towards a humoral response whereas the more effective immune response may be a cell-mediated response.
• 1 1 ⁇ -HSD1 inhibitors may be useful for treating such diseases.
• novel compounds of the instant invention are effective inhibitors of 11 ⁇ -HSD1.
