Selective antagonists of mouse trace amine-associated receptor 1 (mTAAR1): discovery of EPPTB (RO5212773)

Bioorg Med Chem Lett. 2011 Feb 15;21(4):1227-31. doi: 10.1016/j.bmcl.2010.12.075. Epub 2010 Dec 21.

Abstract

High throughput screening of the Roche compound library identified benzanilides such as 1 and 2 as antagonists of TAAR1. Optimisation of this hit series led to the first selective TAAR1 antagonist (N-(3-Ethoxy-phenyl)-4-pyrrolidin-1-yl-3-trifluoromethyl-benzamide EPPTB (RO5212773, 9f) having IC(50) of 28 nM at mouse TAAR1.
