Two series of simplified analogs of the ecteinascidin-saframycin type alkaloids were prepared from l-DOPA. Their in vitro antitumor activity was tested against three human cancer cell lines (HCT-8 colon carcinoma, Bel-7402 liver carcinoma, and BGC-823 gastric carcinoma). Among these compounds, the ester analogs have stronger activities than those of amide analogs in general. Among them, 1-naphthalene carboxylate ester analog 31 has the strongest activity against BGC-823 cells.
以L-多巴为原料制备了两类简化的埃博霉素-沙弗霉素型生物碱类似物。测试了它们对三种人类癌细胞系(HCT-8结肠癌、Bel-7402肝癌和BGC-823胃癌)的体外抗肿瘤活性。在这些化合物中,酯类类似物的活性总体上比酰胺类类似物更强。其中,1-萘羧酸酯类似物31对BGC-823细胞的活性最强。
