阿托品及东莨菪碱可增加离体大脑皮层薄片乙酰胆碱(Ach)在高钾或电刺激情况下的诱发释放及合成, 此作用很可能是由于阻断了胆碱能突触前受体的负反馈机制所致。樟柳碱是由唐古特东莨菪的根提出的生物碱,其结构类似东莨菪碱,只是在托品酸部分多一个羟基。其中枢和外周作用及其代谢已有报道。关于其对整体动物皮层Ach释放的影 Atropine and scopolamine increase the release and synthesis of acetylcholine (Ach) in isolated rat cortical slices under high potassium or electrical stimulation, which may be due to the negative feedback mechanism that blocks the cholinergic presynaptic receptors To Anisodine is an alkaloid proposed by the root of Tangut scopine, which is similar in structure to scopolamine except that it has one more hydroxyl group in the tropic acid moiety. Its central and peripheral effects and their metabolism have been reported. About its impact on the release of Ach in the whole animal cortex
