Synthesis of 2,5-disubstituted-1,3,4-oxadiazole (2a–c), 3-substituted aminomethyl-5-substituted-1,3,4-oxadiazole-2(3H)-thione (4a–m) and 2-substituted thio-5-substituted-1,3,4-oxadiazole (5a, b) had been described. All the synthesized derivatives were screened for anticancer activity against HT29 and MCF7 cancer cell lines using Sulfo-Rodamine B (SRB) standard method. Most of the tested compounds exploited potent antiproliferative activity against HT29 cancer cell line rather than MCF7 cancer cell line. Compounds 2a–c, 4f and 5a exhibited potent cytotoxicity (IC50 1.3–2.0 µM) and selectivity against HT29 cancer cell line. Quantitative structure–activity relationship (QSAR) study was applied to find a correlation between the experimental antiproliferative activities of the newly synthesized oxadiazole derivatives with their physicochemical parameter and topological index.
2,5- 二取代-1,3,4-噁二唑(2a-c)、3-取代氨甲基-5-取代-1,3,4-噁二唑-2(3H)-硫酮(4a-m)和 2-取代硫代-5-取代-1,3,4-噁二唑(5a, b)的合成已被描述。采用磺胺罗丹明 B(SRB)标准方法筛选了所有合成衍生物对 HT29 和 MCF7 癌细胞系的抗癌活性。大多数受试化合物都对 HT29 癌细胞株而不是 MCF7 癌细胞株具有很强的抗增殖活性。化合物 2a-c、4f 和 5a 对 HT29 癌细胞株具有很强的细胞毒性(IC50 1.3-2.0 µ<小>M小>)和选择性。定量结构-活性关系(QSAR)研究发现了新合成的噁二唑衍生物的实验抗增殖活性与其理化参数和拓扑指标之间的相关性。
