以去氢表雄酮为原料, 通过微波一步合成法及常规2步合成方法合成得到16个新的具有不同结构特征的去氢表雄酮噻唑衍生物. 所有合成物都通过了IR、NMR及HRMS的结构表征. 另外, 分别选用人宫颈癌细胞(HeLa)、人肝癌细胞(HepG)、人肺癌细胞(A549)和人正常肾上皮细胞(HEK-293T)对合成物的抗肿瘤活性进行了研究, 结果表明4-(4'-三氟甲基)苯基噻唑-2-去氢表雄酮腙(4)对所测试的肿瘤细胞株具有很好的生长增殖抑制活性, 对上述肿瘤细胞的IC50值分别为13.2、11.3和8.3 μmol·L-1, 对人肾上皮正常细胞HEK-293T却没有表现出明显的抑制作用(IC50值>100 μmol·L-1). 但是, 其它合成物对所测试的细胞株没有表现出明显的抑制活性.

Using dehydroepiandrosterone as starting material, 16 dehydroepiandrosteronyl thiazol derivatives with different structures had been synthesized via microwave irradiation assisted one-pot reaction and general synthetic method, and their structures were characterized by IR, NMR and HRMS. The antiproliferative activity of the compounds was evaluated against human cervical carcinoma (HeLa), human lung carcinoma (A549), human liver carcinoma cells (HEPG2) and normal kidney epithelial cells (HEK293T). The results showed that compound 4 displayed significant inhibitory activity to tested cancer cells, and the values of IC50 were 13.2, 11.3 and 8.3 μmol·L-1 respectively, but was almost inactive to HEK293T cells (IC50>100 μmol·L-1). However, other compounds did not exhibit distinct antiproliferative activity to all tested cells.
