The M, mAChR is implicated in several CNS disorders and possesses an allosteric binding site for which ligands modulating the affinity and/or efficacy of ACh may be exploited for selective receptor targeting. We report the synthesis of a focused library of putative M-4 PAMs derived from VU0152100 and VU10005. These compounds investigate the pharmacological effects of previously identified methoxy and fluoro substituents, providing useful estimates of affinity (K-B), cooperativity (alpha beta), and direct agonist properties (tau(B)).
