Abstract

This Letter describes a chemical lead optimization campaign directed at VU0119498, a pan G(q) mAChR M(1), M(3), M(5) positive allosteric modulator (PAM) with the goal of developing a selective M(1) PAM. An iterative library synthesis approach delivered a potent (M(1) EC(50)=830 nM) and highly selective M(1) PAM (>30 microM vs M(2)-M(5)).
