取代苯甲醛与4-氨基-5-(3,4,5-三甲氧基苯基)-1,2,4-三唑-3-硫酮(2)缩合生成 5-(3,4,5-三甲氧基苯基)-4-取代苯基亚胺基-1,2,4-三唑-3-硫酮(3), 再烷基加成化为新型5,6-2H-1,2,4-三唑[3,4-b][1,3,4]噻二嗪衍生物(4). 化合物结构经1H NMR, 13C NMR, IR以及元素分析确认. 采用MTT法进行化合物抑制PC3癌细胞体外活性测试, 结果表明所合成的化合物具有不同程度的抑制PC3癌细胞活性, 其中化合物4a在10μmol?L-1浓度下对PC3的抑制率为75.9 %.

A series of 4-(substituted-3-phenylideneamino)-3-(3,4,5-trimethoxyphenyl)- 1H-1,2,4-triazole-5(4H)-thione 3 were synthesized by condensation reaction of 4-amino-3-(3,4,5-trimethoxyphenyl)-1H-1,2,4-triazole-5(4H)-thione (2) with various substituted benzaldehydes. Alkylation of 3 with alkyl halides afforded [1,2,4]triazolo- [3,4-b][1,3,4]thiadiazine derivatives 4. Their structures were confirmed by 1H NMR, 13C NMR, IR and elemental analyses. Preliminary bioassay indicated that some compounds posed antitumor activity to PC3 cells in vitro by MTT method. The antiproliferation activity of compound 4a to PC3 cells at the concentration of 10 μmol?L-1 was 75.9 %.
