and topo-II) have occupied a significant role in DNA replication, transcription, and are a promising set of antitumor targets. In the present approach, a series of new 4β-amidotriazole linked podophyllotoxin derivatives (10a-i and 11a-k) were designed, synthesized by employing the click chemistry and their biological activities were evaluated. The majority of derivatives showed promising antiproliferative
拓扑异构酶(topo-I和topo-II)在DNA复制,转录中起着重要作用,并且是一组有希望的抗肿瘤靶标。在本方法中,一系列新的4个β -amidotriazole联鬼臼毒素衍生物(10A-I和图11A-K )被设计,通过采用点击化学和它们的生物活性进行了评价合成。大多数衍生物在六种人类癌细胞系上显示出令人鼓舞的抗增殖活性,IC 50值范围为1至10μM。宫颈(HeLa),乳腺(MCF-7),前列腺(DU-145),肺(A549),肝(HepG2)和结肠(HT-29)。其中一些同类物10b,10g和10i已显示出显着的细胞毒性,对测试的癌细胞系的IC 50值<1μM,并且比依托泊苷具有更高的活性。拓扑异构酶介导的DNA弛豫试验结果表明,该衍生物能有效抑制拓扑异构酶II的活性。此外,对DU-145细胞的流式细胞仪分析表明,这些化合物可阻止细胞周期的G2 / M期。还对这些DU-145细胞进行
