An asymmetric synthesis of a series of novel 4-methyl-(3'S,4'S)-cis-khellactone derivatives 3a-o is reported for the first time. Their structures were confirmed by 1H-NMR, 13C-NMR and MS. Their cytotoxic activity was evaluated by the MTT assay against three selected human cancer cell lines: HEPG-2 (human liver carcinoma), SGC-7901 (human gastric carcinoma), LS174T (human colon carcinoma). Some compounds
首次报道了一系列新型 4-甲基-(3'S,4'S)-顺式-海胆内酯衍生物 3a-o 的不对称合成。它们的结构经 1H-NMR、13C-NMR 和 MS 证实。它们的细胞毒活性通过 MTT 测定法针对三种选定的人类癌细胞系进行评估:HEPG-2(人类肝癌)、SGC-7901(人类胃癌)、LS174T(人类结肠癌)。一些化合物对这些人类癌细胞系显示出高抑制活性。其中,化合物3a表现出较强的细胞毒性,IC50值为8.51~29.65 μM。结果表明,具有 S,S 构型的 4-甲基-顺-海螺内酯衍生物可能是一种潜在的抗肿瘤剂。
