SAR analysis revealed that the anti-proliferative activity of the xanthones is substantially influenced by the position and number of attached hydroxyl and prenyl groups, and the presence of hydroxyl group ortho to the carbonyl function of xanthone scaffold contributes significantly to their cytotoxicity. The new prenylated xanthone 20 with a relatively simple structure, namely 1,3,8-trihydroxy-2-prenylxanthone
为了探索围绕带有羟基和异戊二烯基部分的蒽酮骨架的详细结构-活性关系(SAR),已合成了29种天然和非天然羟基化和异戊烯化的氧杂蒽酮,并评估了它们对五种人的体外抗增殖活性癌细胞系,包括HepG2(肝细胞癌),HCT-116(结肠癌),A549(肺癌),BGC823(胃癌)和MDAMB-231(乳腺癌)。SAR分析表明,氧杂蒽酮的抗增殖活性受附着的羟基和异戊二烯基的位置和数量的影响很大,而与黄酮骨架的羰基功能邻位的羟基的存在显着影响了它们的细胞毒性。发现具有相对简单结构的新的异戊烯酮黄酮20,即1,3,8-三羟基-2-异戊二烯酮吨酮,对所有五个癌细胞系均表现出与α-Mangostin相当的有效抗肿瘤活性。进一步的机理研究表明,化合物20诱导HepG2细胞凋亡并导致细胞周期停滞在S期。这些结果突出了化合物20作为新型有效的广谱抗肿瘤药物未来开发的潜在新的潜在候选者。
