structurally related to physostigmine with substitution of a methylene group in place of the NMe group at position 8 of physostigmine. Many of these 8-carbaphysostigmine analogues are more potent acetylcholinesterase inhibitors in vitro and less toxic in vivo than physostigmine. The (-)-enantiomer (e.g., 1d and 1g) possessing the same absolute configuration at C3a and C8a as that of physostigmine, is about 6 to
报道了一系列1,2,3,3a,8,8a-六氢茚并[2,1-b]吡咯5-烷基氨基甲酸酯的合成及其拆分。这些化合物在结构上与毒扁豆碱相关,只是取代了毒扁豆碱第8位的NMe基团,用亚甲基取代。与草毒碱相比,许多这些8-carbaphysostigmine类似物在体外是更有效的乙酰胆碱酯酶抑制剂,在体内毒性较小。(-)-对映体(例如1d和1g)在C3a和C8a处具有与毒扁豆碱相同的绝对构型,在抑制乙酰胆碱酯酶方面的效能比相应的(+)-对映体(例如, 1e和1h)。
