Heterobiaryl and heterobiaryl ether derived M5 positive allosteric modulators

This Letter describes a chemical lead optimization campaign directed at VU0238429, the first M5-preferring positive allosteric modulator (PAM), discovered through analog work around VU0119498, a pan Gq mAChR M1, M3, M5 PAM. An iterative parallel synthesis approach was employed to incorporate basic heterocycles to improve physiochemical properties.
