5-dihydroxy benzoic acid involving domino aldol-Michael-oxidation reaction. This is the first report of the synthesis of rugosaflavonoid (6a). A series of its derivatives were also synthesized, characterized and evaluated for the cytotoxicity against the breast cancer MCF-7 and normal NIH3T3 cell lines. The synthetic derivatives of rugosaflavonoid showed comparable activity in both the cell lines and compounds
芸苔黄酮类化合物是从植物中分离出来的次级代谢产物,在五个简单的步骤中从涉及多米诺羟醛-迈克尔-氧化反应的可商购的3,5-二羟基苯甲酸中合成了玫瑰果。这是关于合成总黄酮类化合物(6a)的首次报道。还合成了其一系列衍生物,表征并评估了其对乳腺癌MCF-7和正常NIH3T3细胞系的细胞毒性。黄酮类黄酮的合成衍生物在细胞系和化合物6d,6e和6f中表现出相当的活性。被发现对MCF-7细胞系有细胞毒性,但对5μM浓度的NIH3T3细胞无毒。为了探索最佳活性化合物的作用方式,考虑到EGFR在大多数肿瘤中过表达,对接在EGFR(1M17)的ATP结合位点上。发现6f和标准槲皮素的对接得分(Gscore)分别为-8.608和-8.310。
