摘  要:以吲哚-3-丙酸和吲哚-3-丁酸为原料,分别与炔丙胺发生缩合反应得到3-(丙酰丙炔胺)吲哚(4a)和3-(丁酰丙炔胺)吲哚(4b),然后4a和4b分别与9-(叠氮基乙基氨基)-1,2,3,4-四氢吖啶类衍生物5a~5c在微波辐射下发生Husigen[3+2]环加成反应得到12个新型乙酰胆碱酯酶抑制剂——他克林-吲哚杂二联体,其结构经NMR,IR和HRMS表征.初步生物活性测试表明,目标化合物均具有较强的乙酰胆碱酯酶抑制能力,其中化合物2b和2d抑制鱼鳐乙酰胆碱酯酶的IC50值分别为1.6和2.0 nmol.L-1,是6T6BA(IC50=11.0 nmol.L-1,鱼鳐)的6.9和5.5倍.3-(Propargyl-propionamine)indole(4a) and 3-(propargyl-butyramide)indole(4b) were prepared from indole-3-propionic acid(3a) and indole-3-butyric acid(3b) by condensation with propargylamine,respectively.Twelve novel yl-amino)hexyl]-3-(1H-Indol-3-yl)propionamide(6T6BA)(IC50=11.0 nmol.L-1,electrophorus).acetylcholinesterase inhibitors,tacrine-indole hybrids,were synthesized from 4a,4b and 9-(azido-ethyl-amino)-1,2,3,4-tetrahydroacridine derivatives(5a~5c) by microwave-assisted Huisgen [3+2] cycloaddition reaction.These novel compounds were determined by NMR,IR and HRMS techniques.The preliminary bioassay showed that all of them exhibited better AChE(electrophorus) inhibitory activity.Particularly,the IC50 values of compounds 2b and 2d were 1.6 and 2.0 nmol.L-1 respectively,which were 6.9 and 5.5 times respectively more potent than N-[6-(6-chloro-1,2,3,4-tetrahydroacridin-9-yl-amino)hexyl]-3-(1H-Indol-3-yl)propionamide (6T6BA) (IC50=11.0 nmol L-1, electrophorus).
