Recently, a novel glycosylated diphyllin derivative 11 which exhibiting potent anticancer activity by targeting topoisomerase IIα was reported by our group. In order to provide more molecules for structure-activity relationship (SAR) studies, 12 new glycosylated diphyllin analogs have been designed, synthesized, and evaluated for their biological activities. The SAR analysis revealed that (i) the sugar
最近,我们小组报道了一种新的糖基化二叶素衍生物11,它通过靶向拓扑异构酶 IIα 表现出有效的抗癌活性。为了为构效关系 (SAR) 研究提供更多分子,我们设计、合成了 12 种新的糖基化叶木素类似物,并对其生物活性进行了评估。SAR 分析表明 (i) diphyllin 上的糖部分对于抗癌活性是必不可少的;(ii) 糖上的赤道 C4'-OH 优于轴向的,并且 (iii) 糖的 C4' 和 C6' 处适当的环状亲脂基团可能会增强抗癌活性。
