Using a high-throughout screening approach, the anticancer activities of 16 O-methylated (OMe) analogs of quercetin were assessed. The structure-activity relationships showed that OMe moieties at the 4' and/or 7 positions were important for maintaining inhibitory activities against the 16 cancer cell lines. Furthermore, when the OH groups at the 3' and 4' positions were both replaced by OMe moieties, anticancer activity was enhanced.
采用高通量筛选方法，评估了槲皮素的16种O-甲基化（OMe）类似物的抗癌活性。构效关系表明，4'和/或7位的OMe基团对于维持对16种癌细胞系的抑制活性很重要。此外，当3'和4'位的OH基团都被OMe基团取代时，抗癌活性增强。
