摘要: 根据生物等排原理和新烟碱类化合物与乙酰胆碱酯酶的作用机理, 以4-噻唑啉酮(4)为中间体设计合成了2-取代-3-(2-氯-5-吡啶亚甲基)-4-氰基亚胺基-1,3-噻唑烷(8a~8c)和5-芳基次甲基-2-芳基-3-(2-氯-5-吡啶亚甲基)-4-噻唑啉酮(5a~5e)两类化合物. 中间体(4)由醛、胺和巯基乙酸缩合得到. 所有化合物的结构均经元素分析和1H NMR确证. 初步生物活性试验结果表明, 部分化合物具有一定的杀菌活性和促进黄瓜子叶生根活性, 化合物8b显示出很好的抗HIV-1蛋白酶活性.

Abstract: According to bioisosteric relationship and the mode of action between Neonicotinoid compounds and acetylcholin esterase, two series of Neonicotinoid compounds 2-substituted-3-(2-chloro-5-pyridinemethylene)-4-cyanoimino-1,3-thiazolidine(8a—8c) and 5-arylidene-2-aryl-3-(2-chloro-5-pyridinemethylene)-4-thiazolidinones(5a—5e) were designed and synthesized from 4-thiazolidinones(4). Intermediates 4 were synthesized by the condensation of amine, aldehyde and mercapto acetic acid. Their structures were character-ized via elemental analysis, 1H NMR spectra. The preliminary bioassay results show that some title compounds exhibited certain fungicidal activities, promoting cucumber cotyledon root-formation activities and compound 8b showed favourable anti-HIV PR.
