Discovery of (R)-(2-Fluoro-4-((-4-methoxyphenyl)ethynyl)phenyl) (3-Hydroxypiperidin-1-yl)methanone (ML337), An mGlu3 Selective and CNS Penetrant Negative Allosteric Modulator (NAM)
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) IC50 = 593 nM, mGlu(2) IC50 >30 mu M) 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%.

Herein we report the discovery and SAR of a novel metabotropic glutamate receptor 3 (mGlu(3)) NAM probe (ML289) with 15-fold selectivity versus mGlu(2). The mGlu(3) NAM was discovered via a 'molecular switch' from a closely related, potent mGlu(5) positive allosteric modulator (PAM), VU0092273. This NAM (VU0463597, ML289) displays an IC50 value of 0.66 mu M and is inactive against mGlu(5). (C) 2012 Elsevier Ltd. All rights reserved.
