Abstract

This Letter describes a chemical lead optimization campaign directed at VU0108370, a weak M(1) PAM hit with a novel chemical scaffold from a functional HTS screen within the MLPCN. An iterative parallel synthesis approach rapidly established SAR for this series and afforded VU0405652 (ML169), a potent, selective and brain penetrant M(1) PAM with an in vitro profile comparable to the prototypical M(1) PAM, BQCA, but with an improved brain to plasma ratio.
