The identification of an MCH R1 antagonist screening hit led to the optimization of a class of benzimidazole-based MCH R1 antagonists. Structure-activity relationships and efforts to optimize pharmacokinetic properties are detailed along with the demonstration of the effectiveness of an MCH R1 antagonist in an animal model of obesity.

A chemically diverse library of about 400,000 small molecules was screened for antiviral activity against lentiviral pseudotypes with the Lassa virus envelope glycoprotein (LASV GP) gene incorporated. High-throughput screening resulted in discovery of a hit compound (ST-37) possessing a benzimidazole core which led to a potent compound series. Herein, we report SAR studies which involved structural modifications to the phenyl rings and methylamino linker portion attached to the benzimidazole core. Many analogs in this study possessed single digit nanomolar potency against LASV pseudotypes. Compounds in this benzimidazole series also exhibited nanomolar antiviral activity against pseudotypes generated from other arenavirus envelopes indicating the potential for development of a broad-spectrum inhibitor. Ultimately, lead compound ST-193 was identified and later found to be efficacious in a lethal LASV guinea pig model showing superior protection compared to ribavirin treatment. (c) 2012 Elsevier Ltd.
