(HepG2) were used to evaluate the cytotoxic activities of xanthone derivatives by acid phosphatase assay. Analyses showed that the oxiranylmethoxy substituted xanthone exhibited more effective cytotoxic activity against the cancer cells than the other substituted xanthones. The effects on the inhibition of tumor cells in vitro agreed with the studies of DNA-binding.
在这项研究中,通过分光光度法和粘度测量研究了不同基团取代的异异黄酮衍生物与小牛胸腺DNA(ct DNA)的相互作用。结果表明,x吨酮衍生物可以通过an吨酮环的平面插入DNA碱基对中,并且根据计算的猝灭常数值,各种取代基可能影响与DNA的结合亲和力。此外,包括人宫颈癌细胞系(HeLa)和人肝细胞肝癌细胞系(HepG2)在内的两种肿瘤细胞系被用于通过酸性磷酸酶测定来评估x吨酮衍生物的细胞毒活性。分析表明,氧杂氧基甲氧基取代的蒽酮对癌细胞具有比其他取代的氧杂蒽酮更有效的细胞毒活性。
