Background

Atropine is a competitive antagonist of muscarinic acetylcholine receptor with IC50 values of 2.22±0.60nM, 4.32±1.63nM, 4.16±1.04nM, 2.38±1.07nM and 3.39±1.16nM for M1, M2, M3, M4 and M5, respectively [1].

Atropine is an antimuscarinic agent and has shown the pharmacological effects because of binding to muscarinic acetylcholine receptors. Atropine, the orthosteric antagonist, has been reported to compete with [3H]-NMS for all muscarinic subtypes with a potency consistent with the high affinities at the mAChR subtypes. The Ki values are 1.27±0.36nM, 3.24±1.16nM, 2.21±0.53nM, 0.77±0.43nM and 2.84±0.84nM, respectively [1, 2, 3].
