摘要

A multidimensional, iterative parallel synthesis effort identified a series of highly selective mGlu_3 NAMs with submicromolar potency and good CNS penetration. Of these, ML337 resulted (mGlu_3 IC_(50) = 593 nM, mGlu_2 IC_(50) >30 μM) with B:P ratios of 0.92 (mouse) to 0.3 (rat). DMPK profiling and shallow SAR led to the incorporation of deuterium atoms to address a metabolic soft spot, which subsequently lowered both in vitro and in vivo clearance by >50%.
