Abstract

This Letter describes the further optimization of an MLPCN probe molecule (ML137) through the introduction of 5- and 6-membered spirocycles in place of the isatin ketone. Interestingly divergent structure-activity relationships, when compared to earlier M1 PAMs, are presented. These novel spirocycles possess improved efficacy relative to ML137, while also maintaining high selectivity for the human and rat muscarinic M1 receptor subtype.
