thiosemicarbazides 2 under basic and acidic conditions, respectively. The thiosemicarbazides, in turn, were prepared by the reaction of hydrazides 1 with 4-chlorophenylisothiocyanate in MeOH. Some of the new synthesized compounds were assayed against HIV-1 and HIV-2 in MT-4 cells. All the compounds were inactive except 3f, which showed an EC50 value of 23.9 μg/mL and 9.9 μg/mL against HIV-1 and HIV-2 with
5-取代的 4-(4-氯苯基)-4H-1,2,4-三唑-3-硫酮 3 和 2-取代的 5-(4-氯苯基氨基)-1,3,4-噻二唑 4 由中间体制备氨基硫脲 2 分别在碱性和酸性条件下。氨基硫脲又是通过酰肼 1 与 4-氯苯基异硫氰酸酯在 MeOH 中反应制备的。一些新合成的化合物在 MT-4 细胞中对 HIV-1 和 HIV-2 进行了检测。除 3f 外,所有化合物均无活性,其对 HIV-1 和 HIV-2 的 EC50 值为 23.9 μg/mL 和 9.9 μg/mL,治疗指数分别为 3 和 7。这意味着化合物 3f 在两种菌株中的 CC50 均为 72.7 μg/mL 时对 MT-4 细胞具有细胞毒性。© 2007 Wiley Periodicals, Inc. 杂原子化学 18:316–322, 2007; 在线发表于 Wiley InterScience (www.interscience
