The synthesis of a series of andrographolide-19-oic acid derivatives was described and their in vitro anti-tumor activity against two human cell lines was evaluated. Most compounds were found to exhibit significant cytotoxicity, better than andrographolide, and compounds 9d and 9b were identified as the most potent with IC50 values of 1.18 and 6.28 μm against HCT-116 and MCF-7 cell lines, respectively
描述了一系列穿心莲内酯-19-油酸衍生物的合成,并评估了它们对两种人细胞系的体外抗肿瘤活性。发现大多数化合物表现出明显的细胞毒性,优于穿心莲内酯,并且化合物9d和9b被鉴定为最有效的化合物,分别对HCT-116和MCF-7细胞系的IC 50值为1.18和6.28μm。初步结果表明穿心莲内酯的C-19-羟基氧化为相应的羧基,随后形成的羧酸酯化,导致对癌细胞的细胞毒性有了很大的改善。
