Design, Synthesis, and Structure−Activity Relationship of Tropane Muscarinic Acetylcholine Receptor Antagonists
摘要:
Novel tropane derivatives were characterized as muscarinic acetylcholine receptor antagonists (mAChRs). Through optimization of the structure-activity relationship around the tropane scaffold, the quaternary ammonium salt 34 was identified as a very Potent M(3) mAChR antagonist. The compound was functionally active and displayed greater than 24 It duration of action in a mouse model of bronchoconstriction.

three naturally occurring tropane esters has been developed and one of the ketones has been evaluated for its efficacy as a muscarinic acetylcholine receptor (mAChR) antagonist in guinea-pig ileum. The ketone analogue of apoatropine displayed an IC50 value in the micromolar range when compared to atropine, which has antagonist activity in the nanomolar range. The conformational change in replacing the
