Sulfide Analogues as Potent and Selective M(2) Muscarinic Receptor Antagonists

Bioorg Med Chem Lett. 2002 Apr 8;12(7):1087-91. doi: 10.1016/s0960-894x(02)00096-3.

Abstract

We have discovered highly potent, selective sulfide M(2) receptor antagonists with low molecular weight and different structural features compared with our phase I clinical candidate Sch 211803. Analogue 30 showed superior M(2) receptor selectivity profile over Sch 211803. More importantly, this study provided new leads for the discovery of M(2) receptor antagonists as potential drug candidates.
