设计并合成了一系列1,2,4-三唑-3-硫醚衍生物,目标化合物的化学结构经1H NMR、13C NMR、质谱和元素分析确证;采用单晶X射线衍射法测定了(E)-4-(4-羟基-3-甲氧基苯基亚甲氨基)-5-乙基-4H-1,2,4-三唑-3-丙硫醚(1c)的晶体结构.目标化合物体外神经氨酸酶(Neuraminidase,NA,H1N1)抑制活性测试结果表明,大部分化合物1具有较好的NA抑制活性,其中(E)-4-(4-羟基-3-甲氧基苯基亚甲氨基)-5-乙基-4H-1,2,4-三唑-3-乙硫醚(1b)和1c的NA抑制活性最佳,其IC50值分别为(6.86±2.08)和(9.1±1.56)μg/mL.

A series of 1,2,4-triazole-3-sulfide derivatives were designed and synthesized. Their chemical structures were confirmed by 1H NMR, 13C NMR, MS and elemental analysis. The crystal structure of (E)-4-(4-hydroxy-3-methoxyphenyl-methyleneamino)-5-ethyl-4H-1,2,4-triazole-3-propylsulfide (1c) was determined by X-ray diffraction analysis. The preliminary assay of neuraminidase (NA, H1N1) inhibitory activity in vitro showed that most of compound 1 has more potent NA inhibitory activity. Among them, compounds (E)-4-(4-hydroxy-3-methoxyphenyl-methyleneamino)-5-ethyl-4H-1,2,4-triazole-3-ethylsulfide (1b) and 1c showed the best inhibitory activity with IC50 values of (6.86±2.08) and (9.1±1.56) μg/mL, respectively.
