Scopolamine is a competitive muscarinic acetylcholine receptor with an IC50 of 55.3 ± 4.3 nM. It is a tropane alkaloid compound 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.

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
