Notes: Scopolamine is an alkaloid that has been found in D. stramonium and has diverse biological activities.{31350,27107,46375,61178,18345,66637} It is an antagonist of muscarinic acetylcholine receptors (mAChRs; Kis = 0.19, 1.41, and 0.18 nM for the rat M1, M2, and M3 receptors, respectively).{27107} Scopolamine reduces acetylcholine-induced contractions in isolated guinea pig ileum (IC50 = 8.1 nM).{46375} It inhibits tremors induced by the mAChR agonist oxotremorine (Item No. 35707) in mice (ED50 = 0.23 mg/kg). Scopolamine increases fine motor activity counts and ambulatory activity in rats in a home-cage activity test (ED50 = 0.12 mg/kg for both).{61178} It has been used to induce learning deficiencies or amnesia in animal models.{18345,66637} Formulations containing scopolamine have been used in the treatment of motion sickness and postoperative nausea and vomiting.
