生物活性
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.

例如,依据体表面积折算法,将化合物用于小鼠的剂量20 mg/kg 换算成大鼠的剂量,需要将20 mg/kg 乘以小鼠的Km系数(3),再除以大鼠的Km系数(6),得到化合物用于大鼠的等效剂量为10 mg/kg。
