This letter describes a diversity-oriented library approach to rapidly assess diverse heterocycles as bioisosteric replacements for a metabolically labile amide moiety within a series of mGlu(7) negative allosteric modulators (NAMs). SAR rapidly honed in on either a 1,2,4- or 1,3,4-oxadizaole ring system as an effective bioisostere for the amide. Further optimization of the southern region of the mGlu(7) NAM chemotype led to the discovery of VU6019278, a potent mGlu(7) NAM (IC50=501 nM, 6.3% L-AP4 Min) with favorable plasma protein binding (rat f(u)=0.10), low predicted hepatic clearance (rat CLhep=27.7 mL/min/kg) and high CNS penetration (rat K-p=4.9, K-p,K-uu=0.65).
