A series of novel tetrahydrobenzothieno[2,3-d]pyrimidine urea derivatives was synthesized according to fragment-based design strategy. They were evaluated for their anticancer activity against MCF-7 cell line. Three compounds 9c, 9d and 11b showed 1.5–1.03 folds more potent anticancer activity than doxorubicin. In this study, a promising multi-sited enzyme small molecule inhibitor 9c, which showed
根据基于片段的设计策略,合成了一系列新颖的四氢苯并噻吩并[2,3- d ]嘧啶脲衍生物。评价它们对MCF-7细胞系的抗癌活性。三种化合物9c,9d和11b的有效抗癌活性比阿霉素高1.5-1.03倍。在这项研究中,鉴定出了显示出最有效的抗增殖活性的有前途的多部位酶小分子抑制剂9c。该化合物的抗增殖活性似乎与其抑制拓扑异构酶II的能力密切相关(IC 50 = 9.29μM)。此外,化合物9c在亚微摩尔水平显示出优异的VEGFR-2抑制活性,IC 50值为0.2μM,效力比索拉非尼高2.1倍。此外,DNA损伤反应途径的激活导致细胞周期停滞在G2 / M期,G1期前细胞蓄积,膜联蛋白V和碘化丙锭染色,表明细胞死亡是通过凋亡机制进行的。化合物9c通过诱导内在的线粒体凋亡途径,显示出有效的促凋亡作用。肿瘤抑制基因p53的表达显着增加,Bax / BCL-2比的升高以及活性caspase-3的水平显着
