Substituted azole derivatives as inhibitors of corticotropin releasing factor

Description

FIELD OF THE INVENTION

[0002] The present invention relates to thiazoles, oxazoles, imidazoles and pharmaceutical compositions comprising said compounds antagonizing the corticotropin releasing factor receptor (“CRF receptor”) and useful for the treatment of depression, anxiety, affective disorders, feeding disorders, post-traumatic stress disorder, headache, drug addiction, inflammatory disorders, drug or alcohol withdrawal symptoms and other conditions the treatment of which can be effected by the antagonism of the CRF-1 receptor.

BACKGROUND OF THE INVENTION

[0003] It has been shown that the neuropeptide, corticotropin releasing factor (“CRF”), acting through its binding to the CRF-1 receptor, is a primary mediator of stress- and anxiety-related physiological responses in humans and other mammals by stimulating ACTH secretion from the anterior pituitary gland. See A. J. Dunn, et al., Brain Res. Rev., 15: 71-100 (1990). Antagonists of the CRF-1 receptor, both peptides (J. Gulyas, et al., Proc. Natl. Acad. Sci. U.S.A., 92: 10575-10579 (1995) and small molecules (J. R. McCarthy, et al., Curr. Pharm. Design, 5: 289-315 (1999), have demonstrated the ability to ameliorate the effects of stressful stimuli in several animal models. In addition, marked elevations of CRF in cerebrospinal fluid have been detected in a large portion of individuals diagnosed with major depression and anxiety disorders, and the levels correlate with severity of the disease. See F. Holsboer, J. Psychiatric Res., 33: 181-214 (1999). Following antidepressant treatment, the increased CRF levels observed in depressed patients were reduced. See C. M. Banki, et al., Eur. Neuropsychopharmacol., 2: 107-113 (1992). CRF has also been shown to be a key mediator of several immune system functions through its effect on glucocorticoid plasma levels. See E. L. Webster, et al., Ann. N.Y. Acad. Sci., 840: 21-62 (1998). Recent reviews of the activity of CRF-1 antagonists, P. J. Gilligan, et al., J. Med. Chem., 43: 1641-1660 (2000) and J. R. McCarthy, et al., Ann. Rep. Med. Chem., 34: 11-20 (1999) are incorporated herein by reference. There appears a need to discover novel small molecule CRF antagonists in order to treat a wide variety of human disorders including depression, anxiety, bipolar disorder, and other stress-related illnesses. See WO 95/10506, WO 95/33750, WO 97/14684, WO 97/35580, WO 98/11075, WO 98/42699, WO 99/01439 and EP 773023.

The mixture was allowed to stand overnight at room temperature and then the solvents were evaporated. The residue was partitioned between ethyl acetate and water. The organic phase was washed with brine, dried over sodium sulfate and evaporated. The product was purified by chromatography on silica gel, eluting with 10% ethyl acetate/hexane, to give a colorless oil (161.8 mg, 100%).

CRF1 Receptor Binding Protocol

[0393] CRF1 receptor antagonists, by occupying the same receptors, blocks the accessibility of the receptors to CRF, a hypothalamic factor mediating body's responses to physiological and psychological stress. The following radioligand binding assay examines the ability of the antagonists to bind the CRF1 receptors by assessing their ability to compete with binding of CRF to the receptors in cell membrane.

[0396] IMR-32 cells were grown at 37° C. in 5% CO2 as a monolayer in medium consisting of MEM supplemented with 10% heat-inactivated fetal bovine serum, 0.1 mM nonessential amino acids, 1 mM sodium pyruvate and 2 mM L-glutamine. Cells were transformed by exposure to 2.5 μM 5′-bromo-2′-deoxyuridine for 10 days. After transformation, cells were rinsed twice with phosphate-buffered saline, and incubated for 10-15 min. at 4° C. in homogenization buffer consisting of 50 mM Tris (pH 7.2), 10 mM MgCl2 and 2 mM EGTA. Cells were transferred from plates to polypropylene tubes (16×100 mm), homogenized and centrifuged at 32,000×g for 15 min. Pellets were resuspended by homogenization in buffer and centrifuged at 32,000×g for 15 min. Pellets were resuspended in homogenization buffer then stored at −80° C. until needed.

[0397] Radioligand Binding Assays.

[0398] Membranes (150 μg/well) were incubated with [125I]-oCRF (100 μM) and increasing concentrations of test compound for 100 minutes at 25° C. in a total volume of 200 μl. The assay buffer consisted of 50 mM Tris (pH 7.2), 10 mM MgCl2, 0.5% BSA, 0.005% Triton X-100, 10 μg/ml aprotinin and 10 μg/ml leupeptin. Assays were stopped by addition of ice-cold wash buffer (50 mM Tris, pH 7.4 and 0.2% BSA). Filtration over glass fiber filters (Whatman GF/B) previously soaked in 50 mM Tris, pH 7.2 and 1% BSA was carried out using a Brandel cell harvester. Filters were washed with 10 ml of ice-cold wash buffer. Non-specific binding was defined with 10 μM oCRF. IC50 values for oCRF and test compounds were calculated by nonlinear regression using a one-site binding curve (GraphPad Prism).
