4-Bicyclic heteroaryl-piperidine derivatives as potent, orally bioavailable Stearoyl-CoA desaturase-1 (SCD1) inhibitors. Part 1: Urea-based analogs
摘要:
A new series of urea-based, 4-bicyclic heteroaryl-piperidine derivatives as potent SCD1 inhibitors is described. The structure-activity relationships focused on bicyclic heteroarenes and aminothiazole-urea portions are discussed. A trend of dose-dependent decrease in body weight gain in diet-induced obese (DIO) mice is also demonstrated. (C) 2013 Elsevier Ltd. All rights reserved.

A novel efficient synthetic route to the pharmaceutical key intermediate N-(piperidin-4-yl)-1,3-dihydroindol-2-one is described. The key step involves a high-yielding intramolecular palladium-catalyzed amination reaction using Buchwald's X-Phos ligand under mild reaction conditions. (C) 2004 Elsevier Ltd. All rights reserved.
