A series of isatin-3-ylidene (6a-i) and arylthiazolyl-1,3,4-oxadiazole-2-thione derivatives 7a-i derived from arylthiazolyl carbohydrazide analogs 4a-i were synthesized. Analogously, coupling of 4f with various amino acid methyl esters in the presence of HOBt/DCC reagents afforded the carboxamide derivatives 9a-d. The newly synthesized compounds were assayed against HIV-1 and HIV-2 in MT-4 cells. All compounds are inactive, except compounds 9b and 9c which showed inhibition of HIV-1 with EC50 = 2:34 μg mL-1, and 1.12 μg mL-1 with therapeutic indexes (SI) of 9 and <1, respectively.
从芳基噻唑羧酰肼类似物 4a-i 合成了一系列异汀-3-亚基(6a-i)和芳基噻唑-1,3,4-恶二唑-2-硫酮衍生物 7a-i。同样,在 HOBt/DCC 试剂存在下,将 4f 与各种氨基酸甲酯偶联,可得到羧酰胺衍生物 9a-d。在 MT-4 细胞中对新合成的化合物进行了抗 HIV-1 和 HIV-2 检测。除了化合物 9b 和 9c 对 HIV-1 有抑制作用(EC50 = 2:34 μg mL-1 和 1.12 μg mL-1),治疗指数(SI)分别为 9 和 1 外,其他化合物均无活性。
