毒扁豆碱水杨酸酯是毒扁豆碱的衍生物。毒扁豆碱是一种原始生物，起源于卡拉巴尔豆（| Physostigma venenosum |），并被认为是有效且可逆的胆碱酯酶抑制剂。毒扁豆碱还被报道与乙酰胆碱酯酶（AChE）形成缓慢降解的氨基甲酸酯化酶复合物。在研究乙酰胆碱酯酶抑制剂潜在抗蠕虫药靶标的研究中，该化合物已用作阳性对照。另外，据报道，这种拟副交感神经化合物可穿越血脑屏障。 Physostigmine salicylate is a derivative of Physostigmine . Physostigmine is an alkaloid originally derived from the Calabar bean (|Physostigma venenosum|) and noted to act as a potent and reversible inhibitor of cholinesterase. Physostigmine is also reported to form a slowly degrading carbamylated enzyme complex with acetylcholinesterase (AChE). This compound has been used as a positive control in a study investigating acetylcholinesterase inhibitors for potential antihelminthic drug targets. Additionally, this parasympathomimetic compound is reported to cross the blood-brain barrier.
