Biological Activity:
Scopolamine is a competitive muscarinic acetylcholine receptor with an IC50 of 55.3 ± 4.3 nM. It is a tropane alkaloid drug with muscarinic antagonist effects. It is among the secondary metabolites of plants from Solanaceae (nightshade) family of plants, such as henbane, jimson weed and Angel’s Trumpets (Datura resp. Brugmansia spec.), and corkwood (Duboisia species). It exerts its effects by acting as a competitive antagonist at muscarinic acetylcholine receptors, specifically M1 receptors; it is thus classified as an anticholinergic, anti-muscarinic drug. [1][2]
