5-Aryl-3-(4-hydroxyphenyl)-1,3,4-oxadiazole-2(3H)-thiones 3 were prepared by cyclocondensation of 1-(4-hydroxyphenyl)-2-aroylhydrazines with thiophosgene. All compounds exhibited antiproliferation activity in K562, IC50 ranging from 24 to 94 μM comparable efficacy with apigenin and genistein and showed more potent antiproliferation of K562/adr cells, highly expressing P-glycoprotein. Compounds 3g, 3e and 3a inhibited the function of P-glycoprotein with the α0.5 equal to 10±3 μM, 21±5 μM and 34±7 μM, respectively.
5-Aryl-3-(4-hydroxyphenyl)-1,3,4-oxadiazole-2(3H)-thiones 3 是由 1-(4-羟基苯基)-2-芳酰基肼与硫代磷酰氯环缩合制备的。所有化合物都具有抗 K562 细胞增殖的活性,IC50 为 24 至 94 μ<小>M小>,与芹菜素和染料木素的功效相当,并且对高表达 P 糖蛋白的 K562/adr 细胞的抗增殖作用更强。化合物 3g、3e 和 3a 可抑制 P 糖蛋白的功能,α0.5 分别为 10±3 μ<小>M小>、21±5 μ<小>M小>和 34±7 μ<小>M小>。
