Non-basic azolotriazinone MCHR1 antagonists for the treatment of obesity: An empirical brain-exposures-driven candidate selection for in vivo efficacy studies
摘要:
Non-basic azolotriazinones were explored using an empirical free brain exposures-driven approach to identify potent MCHR1 antagonists for evaluation in in vivo efficacy studies. An optimized lead from this series, 1j (rMCHR1 K-i = 1.8 nM), demonstrated a 6.9% reduction in weight gain relative to vehicle in a rat model at 30 mg/kg after 4 days of once-daily oral treatment as a glycine prodrug. Despite a promising efficacy profile, an assessment of the biliary toxicity risk of this compound rendered this compound non-progressible. (C) 2015 Elsevier Ltd. All rights reserved.
The present application provides compounds that are useful as MCHR1 antagonists, especially for the treatment of obesity, including all stereoisomers, solvates, prodrugs and pharmaceutically acceptable forms thereof according to Formula I
wherein the variables are defined herein.
