Pharmaceutical use of substituted amides

Description

FIELD OF INVENTION

The present invention relates to use of substituted amides and pharmaceutical compositions comprising the compounds for treating disorders where it is desirable to modulate the activity of 11-hydroxysteroid dehydrogenase type 1 (11βHSD1).

The present invention also relates to novel substituted amides, to their use in therapy, to pharmaceutical compositions comprising the compounds, to the use of said compounds in the manufacture of medicaments, and to therapeutic methods comprising the administration of said compounds. The present compounds modulate the activity of 11β-hydroxysteroid dehydrogenase type 1 (11βHSD1) and are accordingly useful in the treatment of diseases in which such a modulation is beneficial, such as the metabolic syndrome.

BACKGROUND OF THE INVENTION

The metabolic syndrome is a major global health problem. In the US, the prevalence in the adult population is currently estimated to be approximately 25%, and it continues to increase both in the US and worldwide. The metabolic syndrome is characterised by a combination of insulin resistance, dyslipidemia, obesity and hypertension leading to increased morbidity and mortality of cardiovascular diseases. People with the metabolic syndrome are at increased risk of developing frank type 2 diabetes, the prevalence of which is equally escalating.

In type 2 diabetes, obesity and dyslipidemia are also highly prevalent and around 70% of people with type 2 diabetes additionally have hypertension once again leading to increased mortality of cardiovascular diseases.

In the clinical setting, it has long been known that glucocorticoids are able to induce all of the cardinal features of the metabolic syndrome and type 2 diabetes.

11β-hydroxysteroid dehydrogenase type 1 (11βHSD1) catalyses the local generation of active glucocorticoid in several tissues and organs including predominantly the liver and adipose tissue, but also e.g. skeletal muscle, bone, pancreas, endothelium, ocular tissue and certain parts of the central nervous system. Thus, 11βHSD1 serves as a local regulator of glucocorticoid actions in the tissues and organs where it is expressed (Tannin et al., J. Biol. Chem., 266, 16653 (1991); Bujalska et al., Endocrinology, 140, 3188 (1999); Whorwood et al., J Clin Endocrinol Metab., 86, 2296 (2001); Cooper et al., Bone, 27, 375 (2000); Davani et al., J. Biol. Chem., 275, 34841 (2000); Brem et al., Hypertension, 31, 459 (1998); Rauz et al., Invest. Ophthalmol. Vis. Sci., 42, 2037 (2001); Moisan et al., Endocrinology, 127, 1450 (1990)).

The role of 11βHSD1 in the metabolic syndrome and type 2 diabetes is supported by several lines of evidence. In humans, treatment with the non-specific 11βHSD1 inhibitor carbenoxolone improves insulin sensitivity in lean healthy volunteers and people with type 2 diabetes. Likewise, 11βHSD1 knock-out mice are resistant to insulin resistance induced by obesity and stress. Additionally, the knock-out mice present with an anti-atherogenic lipid profile of decreased VLDL triglycerides and increased HDL-cholesterol. Conversely, mice that overexpress 11βHSD1 in adipocytes develop insulin resistance, hyperlipidemia and visceral obesity, a phenotype that resembles the human metabolic syndrome (Andrews et al., J. Clin. Endocrinol. Metab., 88, 285 (2003); Walker et al., J. Clin. Endocrinol. Metab., 80, 3155 (1995); Morton et al., J. Biol. Chem., 276, 41293 (2001); Kotelevtsev et al., Proc. Natl. Acad. Sci. USA, 94, 14924 (1997); Masuzaki et al., Science, 294, 2166 (2001)).

The more mechanistic aspects of 11βHSD1 modulation and thereby modulation of intracellular levels of active glucocorticoid have been investigated in several rodent models and different cellular systems. 11βHSD1 promotes the features of the metabolic syndrome by increasing hepatic expression of the rate-limiting enzymes in gluconeogenesis, namely phosphoenolpyuvate carboxykinase and glucose-6-phosphatase, promoting the differentiation of preadipocytes into adipocytes thus facilitating obesity, directly and indirectly stimulating hepatic VLDL secretion, decreasing hepatic LDL uptake and increasing vessel contractility (Kotelevtsev et al., Proc. Natl. Acad. Sci. USA, 94, 14924(1997); Morton et al., J. Biol. Chem. 276, 41293 (2001); Bujalska et al., Endocrinology, 140, 3188 (1999); Souness et al., Steroids, 67, 195 (2002), Brindley & Salter, Prog. Lipid Res., 30, 349 (1991)).

WO 01/90090, WO 01/90091, WO 01/90092, WO 01/90093 and WO 01/90094 discloses various thiazol-sulfonamides as inhibitors of the human 11β-hydroxysteroid dehydrogenase type 1 enzyme, and further states that said compounds may be useful in treating diabetes, obesity, glaucoma, osteoporosis, cognitive disorders, immune disorders and depression.

We have now found substituted amides that modulate the activity of 11βHSD1 leading to altered intracellular concentrations of active glucocorticoid. More specifically, the present compounds inhibit the activity of 11βHSD1 leading to decreased intracellular concentrations of active glucocorticoid. Thus, the present compounds can be used to treat disorders where a decreased level of active intracellular glucocorticoid is desirable, such as e.g. the metabolic syndrome, type 2 diabetes, impaired glucose tolerance (IGT), impaired fasting glucose (IFG), dyslipidemia, obesity, hypertension, diabetic late complications, cardiovascular diseases, arteriosclerosis, atherosclerosis, myopathy, muscle wasting, osteoporosis, neurodegenerative and psychiatric disorders, and adverse effects of treatment or therapy with glucocorticoid receptor agonists.

One object of the present invention is to provide compounds, pharmaceutical compositions and use of compounds that modulate the activity of 11βHSD1.

The presence of polymorphs may be determined by solid probe nmr spectroscopy, ir spectroscopy, differential scanning calorimetry, powder X-ray diffraction or such other techniques.

The invention also encompasses prodrugs of the present compounds, which on administration undergo chemical conversion by metabolic processes before becoming active pharmacological substances. In general, such prodrugs will be functional derivatives of the present compounds, which are readily convertible in vivo into the required compound of the present invention. Conventional procedures for the selection and preparation of suitable prodrug derivatives are described, for example, in “Design of Prodrugs”, ed. H. Bundgaard, Elsevier, 1985.

It is a well known problem in drug discovery that compounds, such as enzyme inhibitors, may be very potent and selective in biochemical assays, yet be inactive in vivo. This lack of so-called bioavailability may be ascribed to a number of different factors such as lack of or poor absorption in the gut, first pass metabolism in the liver and/or poor uptake in cells. Although the factors determining bioavailability are not completely understood, there are many examples in the scientific literature—well known to those skilled in the art—of how to modify compounds, which are potent and selective in biochemical assays but show low or no activity in vivo, into drugs that are biologically active.

It is within the scope of the invention to modify the compounds of the present invention, termed the ‘original compound’, by attaching chemical groups that will improve the bioavailability of said compounds in such a way that the uptake in cells or mammals is facilitated.

Examples of said modifications, which are not intended in any way to limit the scope of the invention, include changing of one or more carboxy groups to esters (for instance methyl esters, ethyl esters, tert-butyl, acetoxymethyl, pivaloyloxymethyl esters or other acyloxymethyl esters). Compounds of the invention, original compounds, such modified by attaching chemical groups are termed ‘modified compounds’.
