Synthesis and optimization of novel and selective muscarinic M3 receptor antagonists

A series of constrained piperidine analogues were synthesized as novel muscarinic M3 receptor antagonists. Evaluation of these compounds in binding assays revealed that they not only have high affinity for the M3 receptor but also have high selectivity over the M2 receptor.
