Synthesis and Structure−Activity Studies of Novel Orally Active Non-Terpenoic 2,3-Oxidosqualene Cyclase Inhibitors
摘要:
New orally active non-terpenoic inhibitors of human 2,3-oxidosqualene cyclase (hOSC) are reported. The starting point for the optimization process was a set of compounds derived from a fungicide project, which in addition to showing high affinity for OSC from Candida albicans showed also high affinity for human OSC. Common structural elements of these inhibitors are an amine residue and an electrophilic carbonyl C atom embedded in a benzophenone system, which are at a distance of about 10.7 Angstrom. Considering that the keto moiety is in a potentially labile position, modifications of the substitution pattern at the benzophenone as well as annelated heteroaryl systems were explored. Our approach combined testing of the compounds first for increased binding affinity and for increased stability in vitro. Most promising compounds were then evaluated for their efficacy in lowering plasma total cholesterol (TC) and plasma low-density lipoprotein cholesterol (LDL-C) in hyperlipidemic hamsters. In this respect, the most promising compounds are the benzophenone derivative 1.fumarate and the benzo[d]-isothiazol 24.fumarate, which lowered TC by 40% and 33%, respectively.

The boron trifluoride-etherate mediated cyclization of 2-arylthio-ketones 1a-h at ambienttemperature gave 3-aryl-substituted benzothiophenes 2a-h in excellent yield. None of the rearranged 2-aryl-substituted benzothiophenes were observed.

Abstract The preparation of 3-aryl benzofuran and benzothiophenes and their dimers at 2-position and, 2-aryl indoles and their 3-position dimers preparation is described. Graphical Abstract
The present invention relates to heteroaromate OSC inhibitors. The compounds are useful for the treatment and/or prophylaxis of diseases which are associated with 2,3-oxidosqualene-lanosterol cyclase such as hypercholesterolemia, hyperlipemia, arteriosclerosis, vascular diseases, mycoses, gallstones, tumors and/or hyperproliferative disorders, and treatment and/or prophylaxis of impaired glucose tolerance and diabetes.
