Definitions

  • the present invention relates to urea derivatives of tropane, to the preparation thereof and to the therapeutic use thereof.
  • the present compounds modulate the activity of the 11 ⁇ -hydroxysteroid dehydrogenase type 1 (11 ⁇ HSD1) and are of use in the treatment of pathologies in which such a modulation is beneficial, as in the case of metabolic syndrome or non-insulin-dependant type 2 diabetes.
  • 11 ⁇ HSD1 11 ⁇ -hydroxysteroid dehydrogenase type 1
  • 11 ⁇ -hydroxysteroid dehydrogenase type 1 (11 ⁇ HSD1) locally catalyzes the conversion of inactive glucocorticoids (cortisone in humans) to active glucocorticoids (cortisol in humans) in various tissues and organs, mainly the liver and the adipose tissue, but also in the muscles, bones, pancreas, endothelium and ocular tissue and in certain parts of the central nervous system.
  • 11 ⁇ HSD1 acts as a regulator of glucocorticoid action in the tissues and organs where it is expressed (Tomlinson et al., Endocrine Reviews 25 (5), 831-866 (2004, Davani et al., J. Biol. Chem. 275, 34841 (2000); Moisan et al., Endocrinology, 127, 1450 (1990)).
  • 11 ⁇ HSD1 in obesity, type 2 diabetes and metabolic syndrome (also known as syndrome X or insulin resistance syndrome), where the symptoms include visceral obesity, glucose intolerance, insulin resistance, hypertension, type 2 diabetes and hyperlipodemia ( Reaven Ann. Rev. Med. 44, 121 (1993)) is described in many publications. In humans, treatment with carbenoxolone (a nonspecific inhibitor of 11 ⁇ HSD1) improves insulin sensitivity in slim volunteer patients and in type 2 diabetics (Andrews et al., J. Clin. Endocrinol. Metab. 88, 285 (2003)).
  • mice in which the 11 ⁇ HSD1 gene has been knocked out are resistant to hyperglycemia induced by stress and obesity, show attenuated induction of liver neoglucogenesis enzymes (PEPCK and G6P) and exhibit an increased sensitivity to insulin in adipose tissue (Kotelevstev et al., Proc Nat. Acad. Sci. 94, 14924 (1997); Morton et al., J. Biol. Chem. 275, 41293 (2001)).
  • PEPCK and G6P liver neoglucogenesis enzymes
  • transgenic mice in which the 11 ⁇ -HSD1 gene has been overexpressed in adipose tissues exhibit a phenotype similar to that of human metabolic syndrome (Masuzaki et al., Science 294, 2166 (2001)). It should be noted that the phenotype observed exists without any increase in total circulating glucocorticoids, but is induced by the specific increase in active glucocorticoids in adipose deposits.
  • 11 ⁇ HSD1 is abundant in the brain and is expressed in many sub-regions, including the hypothalamus, the frontal cortex and the cerebellum (Sandeep et al., Proc. Natl. Acad. Sci. 101, 6734 (2004)). Mice deficient in 11 ⁇ HSD1 are protected against glucocorticoid-associated hypothalamic dysfunctions which are related to aging (Yau et al., Proc. Natl. Acad. Sci. 98, 4716, (2001)). Furthermore, in studies in humans, it has been shown that the administration of carbenoxolone improves verbal fluidity and verbal memory in elderly individuals (Yau et al., Proc. Natl. Acad. Sci.
  • Glucocorticoids can be used topically or systemically for a large variety of pathologies of clinical opthalmology.
  • One particular complication of these treatments is glaucoma induced by the use of corticosteroids.
  • This pathology is characterized by elevated intraocular pressure (IOP).
  • IOP intraocular pressure
  • the IOP may result in a partial loss of visual field and possibly even complete loss of sight.
  • the IOP is the result of an imbalance between the production of aqueous humor and the drainage thereof.
  • the aqueous humor is produced in the non-pigmented epithelial cells and drainage is carried out through the cells of the trabecular network.
  • 11 ⁇ HSD1 is localized in the non-pigmented epithelial cells and its function is clearly the amplification of glucocorticoid activity in these cells (Stokes et al., Invest. Opthalmol. Vis. Sci. 41, 1629 (2000)). This notion is confirmed by the observation that the concentration of free cortisol is in great excess relative to cortisone in the aqueous humor (14/1 ratio).
  • the functional activity of 11 ⁇ HSD1 in the eyes has been evaluated by studying the action of carbenoxolone in normal volunteers. After seven days of treatment with carbenoxolone, the IOP is reduced by 18% (Rauz et al., Invest. Ophthamol. Vis. Sci. 42, 2037 (2001)). The inhibition of 11 ⁇ HSD1 in the eyes is therefore predicted to reduce the local concentration of glucocorticoids and the IOP, producing a beneficial effect on the treatment of glaucoma and of other sight disorders.
  • Hypertensive substances derived from adipocytes such as leptin and angiotensinogen have been proposed as being key elements in obesity-related hypertension pathologies (Wajchenberg et al., Endocr. Rev. 21, 697 (2000)).
  • Leptin which is secreted in excess in transgenic aP2-11 ⁇ HSD1 mice (Masuzaki et al., J. Clinical Invest. 112, 83 (2003)), can activate various networks of sympathetic neuronal systems, including those which regulate arterial pressure (Matsuzawa et al., Acad. Sci. 892, 146 (1999)).
  • RAS renin-angiotensin system
  • Angiotensinogen which is produced in the liver and the adipose tissue, is a key substrate for renin and is responsible for activation of the RAS.
  • the plasma angiotensinogen level is significantly elevated in transgenic aP2-11 ⁇ HSD1 mice, as are those of angiotensin II and of aldosterone (Masuzaki et al., J. Clinical Invest. 112, 83 (2003)); these elements produce an elevated arterial pressure.
  • the treatment of these mice with low doses of an angiotensin II receptor antagonist abolishes this hypertension (Masuzaki et al., J. Clinical Invest. 112, 83 (2003)).
  • This information illustrates the importance of the local activation of glucocorticoids in adipose tissue and the liver, and suggests that this hypertension may be caused or exacerbated by the activity of 11 ⁇ HSD1 in these tissues.
  • the inhibition of 11 ⁇ HSD1 and the reduction of the glucocorticoid level in adipose tissue and/or the liver is therefore predicted as having a beneficial role for the treatment of hypertension and of associated cardiovascular pathologies.
  • 11 ⁇ HSD1 is present in osteoclasts and osteoblasts.
  • the treatment of normal volunteers with carbenoxolone has shown a decrease in bone resorption markers without any change in bone formation markers (Cooper et al., Bone, 27, 375 (2000)).
  • the inhibition of 11 ⁇ HSD1 and the reduction of the glucocorticoid level in the bones could therefore be used as a mechanism of protection in the treatment of osteoporosis.

  • This application is a Divisional of application Ser. No. 12/332,547, filed Dec. 11, 2008, which is a Continuation of International Application No. PCT/FR2007/001070, filed Jun. 26, 2007, both of which re incorporated herein by reference in their entireties.
  • FIELD OF THE INVENTION
  • The present invention relates to urea derivatives of tropane, to the preparation thereof and to the therapeutic use thereof. The present compounds modulate the activity of the 11β-hydroxysteroid dehydrogenase type 1 (11βHSD1) and are of use in the treatment of pathologies in which such a modulation is beneficial, as in the case of metabolic syndrome or non-insulin-dependant type 2 diabetes.
  • BACKGROUND OF THE INVENTION
  • 11β-hydroxysteroid dehydrogenase type 1 (11βHSD1) locally catalyzes the conversion of inactive glucocorticoids (cortisone in humans) to active glucocorticoids (cortisol in humans) in various tissues and organs, mainly the liver and the adipose tissue, but also in the muscles, bones, pancreas, endothelium and ocular tissue and in certain parts of the central nervous system. 11βHSD1 acts as a regulator of glucocorticoid action in the tissues and organs where it is expressed (Tomlinson et al., Endocrine Reviews 25 (5), 831-866 (2004, Davani et al., J. Biol. Chem. 275, 34841 (2000); Moisan et al., Endocrinology, 127, 1450 (1990)).
  • The most important pathologies in which glucocorticoids and the inhibition of 11βHSD1 are involved are indicated below.
  • A. Obesity, Type 2 Diabetes and Metabolic Syndrome
  • The role of 11βHSD1 in obesity, type 2 diabetes and metabolic syndrome (also known as syndrome X or insulin resistance syndrome), where the symptoms include visceral obesity, glucose intolerance, insulin resistance, hypertension, type 2 diabetes and hyperlipodemia (Reaven Ann. Rev. Med. 44, 121 (1993)) is described in many publications. In humans, treatment with carbenoxolone (a nonspecific inhibitor of 11βHSD1) improves insulin sensitivity in slim volunteer patients and in type 2 diabetics (Andrews et al., J. Clin. Endocrinol. Metab. 88, 285 (2003)). Furthermore, mice in which the 11βHSD1 gene has been knocked out are resistant to hyperglycemia induced by stress and obesity, show attenuated induction of liver neoglucogenesis enzymes (PEPCK and G6P) and exhibit an increased sensitivity to insulin in adipose tissue (Kotelevstev et al., Proc Nat. Acad. Sci. 94, 14924 (1997); Morton et al., J. Biol. Chem. 275, 41293 (2001)). Moreover, transgenic mice in which the 11β-HSD1 gene has been overexpressed in adipose tissues exhibit a phenotype similar to that of human metabolic syndrome (Masuzaki et al., Science 294, 2166 (2001)). It should be noted that the phenotype observed exists without any increase in total circulating glucocorticoids, but is induced by the specific increase in active glucocorticoids in adipose deposits.
  • Moreover, new classes of specific 11βHSD1 inhibitors have recently emerged:
      • arylsulfonamidothiazoles have shown that they improve sensitivity to insulin and reduce the blood glucose level in mice exhibiting hyperglycemia (Barf et al., J. Med. Chem. 45, 3813 (2002)). Furthermore, in a recent study, it has been shown that compounds of this type reduce food intake and also weight gain in obese mice (Wang et al., Diabetologia 49, 1333 (2006));
      • triazoles have shown that they improve metabolic syndrome and slow down the progression of atherosclerosis in mice (Hermanowski-Vosatka et al., J. Exp. Med. 202, 517 (2005)).
    B Cognition and Dementia
  • Slight cognitive problems are common phenomena in elderly individuals and can, in the end, result in the progression of dementia. In the case of elderly humans just as in the case of aged animals, inter-individual differences for general cognitive functions have been linked to differences in long-term exposure to glucocorticoids (Lupien et al., Nat. Neurosci. 1, 69, (1998)). Moreover, dysregulation of the HPA (hypothalamic-pituitary-adrenal) axis resulting in chronic exposure of certain sub-regions of the brain to glucocorticoids has been proposed as contributing to the decline of cognitive functions (McEwen et al., Curr. Opin. Neurobiol. 5, 205, 1995). 11βHSD1 is abundant in the brain and is expressed in many sub-regions, including the hypothalamus, the frontal cortex and the cerebellum (Sandeep et al., Proc. Natl. Acad. Sci. 101, 6734 (2004)). Mice deficient in 11βHSD1 are protected against glucocorticoid-associated hypothalamic dysfunctions which are related to aging (Yau et al., Proc. Natl. Acad. Sci. 98, 4716, (2001)). Furthermore, in studies in humans, it has been shown that the administration of carbenoxolone improves verbal fluidity and verbal memory in elderly individuals (Yau et al., Proc. Natl. Acad. Sci. 98, 4716, (2001)), Sandeep et al., Proc. Natl. Acad. Sci. 101, 6734 (2004)). Finally, the use of selective 11βHSD1 inhibitors of triazole type has shown that they prolong memory retention in aged mice (Rocha et al., Abstract 231 ACS meeting, Atlanta, 25-30 Mar. 2006).
  • C. Intraocular Pressure
  • Glucocorticoids can be used topically or systemically for a large variety of pathologies of clinical opthalmology. One particular complication of these treatments is glaucoma induced by the use of corticosteroids. This pathology is characterized by elevated intraocular pressure (IOP). In the most serious cases and for non-treated forms, the IOP may result in a partial loss of visual field and possibly even complete loss of sight. The IOP is the result of an imbalance between the production of aqueous humor and the drainage thereof. The aqueous humor is produced in the non-pigmented epithelial cells and drainage is carried out through the cells of the trabecular network. 11βHSD1 is localized in the non-pigmented epithelial cells and its function is clearly the amplification of glucocorticoid activity in these cells (Stokes et al., Invest. Opthalmol. Vis. Sci. 41, 1629 (2000)). This notion is confirmed by the observation that the concentration of free cortisol is in great excess relative to cortisone in the aqueous humor (14/1 ratio). The functional activity of 11βHSD1 in the eyes has been evaluated by studying the action of carbenoxolone in normal volunteers. After seven days of treatment with carbenoxolone, the IOP is reduced by 18% (Rauz et al., Invest. Ophthamol. Vis. Sci. 42, 2037 (2001)). The inhibition of 11βHSD1 in the eyes is therefore predicted to reduce the local concentration of glucocorticoids and the IOP, producing a beneficial effect on the treatment of glaucoma and of other sight disorders.
  • D. Hypertension
  • Hypertensive substances derived from adipocytes such as leptin and angiotensinogen have been proposed as being key elements in obesity-related hypertension pathologies (Wajchenberg et al., Endocr. Rev. 21, 697 (2000)). Leptin, which is secreted in excess in transgenic aP2-11βHSD1 mice (Masuzaki et al., J. Clinical Invest. 112, 83 (2003)), can activate various networks of sympathetic neuronal systems, including those which regulate arterial pressure (Matsuzawa et al., Acad. Sci. 892, 146 (1999)). Furthermore, the renin-angiotensin system (RAS) has been identified as being a determining pathway in the variation of arterial pressure. Angiotensinogen which is produced in the liver and the adipose tissue, is a key substrate for renin and is responsible for activation of the RAS. The plasma angiotensinogen level is significantly elevated in transgenic aP2-11βHSD1 mice, as are those of angiotensin II and of aldosterone (Masuzaki et al., J. Clinical Invest. 112, 83 (2003)); these elements produce an elevated arterial pressure. The treatment of these mice with low doses of an angiotensin II receptor antagonist abolishes this hypertension (Masuzaki et al., J. Clinical Invest. 112, 83 (2003)). This information illustrates the importance of the local activation of glucocorticoids in adipose tissue and the liver, and suggests that this hypertension may be caused or exacerbated by the activity of 11βHSD1 in these tissues. The inhibition of 11βHSD1 and the reduction of the glucocorticoid level in adipose tissue and/or the liver is therefore predicted as having a beneficial role for the treatment of hypertension and of associated cardiovascular pathologies.
  • E. Osteoporosis
  • Skeletal development and bone functions are also regulated by the action of glucocorticoids. 11βHSD1 is present in osteoclasts and osteoblasts. The treatment of normal volunteers with carbenoxolone has shown a decrease in bone resorption markers without any change in bone formation markers (Cooper et al., Bone, 27, 375 (2000)). The inhibition of 11βHSD1 and the reduction of the glucocorticoid level in the bones could therefore be used as a mechanism of protection in the treatment of osteoporosis.
  • Urea derivatives of tropane which modulate 11βHSD1 activity have now been found.

  • In the following, the term “protective group” (Pg) is intended to mean a group which makes it possible, on the one hand, to protect a reactive function such as a hydroxyl or an amine during a synthesis, and on the other hand, to regenerate the intact reactive function at the end of synthesis. Examples of protective groups and also of the methods of protection and deprotection are given in “Protective Groups in Organic Synthesis”, Green et al., 3rd edition (John Wiley & Sons, Inc., New York).
  • In the following, the term “leaving group” (Lg), is intended to mean a group that can be readily cleaved from a molecule by breaking a heterolytic bond with the departure of a pair of electrons. This group thus can be readily replaced with another group in a substitution reaction, for example. Such leaving groups are, for example, halogens or an activated hydroxyl group such as a mesyl, tosyl, triflate, acetyl, para-nitrophenyl, etc. Examples of leaving groups and references for the preparation thereof are given in “Advances in Organic Chemistry”, J. March, 3rd edition, Wiley Interscience, p. 310-316.
  • In accordance with the invention, the compounds of general formula (I) may be prepared according to the processes hereinafter. In the case where X represents a nitrogen atom, it should be substituted either with a group R2a,b (other than H) or with a protective group Pg as defined above.

The compounds of formulae (I) are obtained by coupling between the activated derivatives (IV) and the amines (V) in the presence or absence of a base such as triethylamine or potassium carbonate, in a solvent such as tetrahydrofuran, dichloromethane, acetonitrile or water, at a temperature ranging from ambient temperature to 100° C.

The heterocycles (X) are obtained by organometallic coupling between a compound (VIII) and a compound (IX) where Y is a derivative of boron (for example, a boronic acid or a boronic ester) or of tin (for example, a tri(n-butyl)tin) or a halogen atom (for example, bromine or iodine), in the presence of a suitable metal derivative (for example, palladium, zinc or copper derivatives) in the presence or absence of a base, such as potassium carbonate, potassium fluoride or sodium phosphate, in a solvent or mixture of solvents, such as dioxane, ethylene glycol dimethyl ether, toluene or water, at a temperature ranging from ambient temperature to 120° C. In a final step, the amines of formula (VI) are obtained by deprotection of the amine function of the compounds of formula (X), by means of methods chosen from those known to those skilled in the art. They comprise, inter alia, the use of trifluoroacetic acid or of hydrochloric acid in dichloromethane, dioxane, tetrahydrofuran or diethyl ether in the case of a protection with a Boc group, and of piperidine for an Fmoc group, at temperatures ranging from −10 to 100° C.
