ganglion-stimulating activity. Among the series of quaternary derivatives, only the isoarecolinol analogues 4a and 4b showed considerable ganglion-stimulating effects, whereas the dihydroisoarecolinol (8), the arecolinol (6a, 6b), and the 3-pyrroline-3-carbinol derivatives (10) were much less potent. Our experiments therefore demonstrate that in this series a quaternary nitrogen atom, unsaturation at C2 of the
[4-[[[N-(3-氯苯基)氨基甲酰基]氧] -2-丁炔基]的一系列叔和季环类似物(异槟榔酚,二氢异槟榔酚,槟榔酚和3-吡咯啉-3-甲醇衍生物)的合成据报道,三甲基氯化铵(McN-A-343)(1)是交感神经节中毒蕈碱受体的选择性刺激剂(所谓的M1受体)。通过记录拔髓大鼠的血压反应,测试化合物3-10的毒蕈碱神经节刺激活性。所有测试的叔化合物均无神经节刺激活性。在一系列季衍生物中,只有异槟榔酚类似物4a和4b表现出明显的神经节刺激作用,而二氢异槟榔酚(8),槟榔酚(6a,6b)和3-吡咯啉-3-甲醇衍生物(10)是效力低得多。
