Abstract
This Letter describes the continued optimization of an MLPCN probe molecule (ML012) through an iterative parallel synthesis approach. After exploring extensive modifications throughout the parent structure, we arrived at a more highly M(1)-selective antagonist, compound 13l (VU0415248). Muscarinic subtype selectivity across all five human and rat receptors for 13l, along with rat selectivity for the lead compound (ML012), is presented.
