(−)-Saframycin A and its nineteen analogues were prepared from l-tyrosine in 24 steps, and their structures were confirmed through NMR and HRMS. The cytotoxicities of these compounds were tested against HCT-8, BEL-7402, Ketr3, A2780, MCF-7, A549, BGC-803, Hela, HELF and KB cell lines. The IC50 values of the cytotoxicity of most compounds were at the level of nM. Compound 7d with 2-furan amide side
由1-酪氨酸分24步制备(-)-沙弗霉素A及其19个类似物,并通过NMR和HRMS确认其结构。测试了这些化合物对HCT-8,BEL-7402,Ketr3,A2780,MCF-7,A549,BGC-803,Hela,HELF和KB细胞系的细胞毒性。大多数化合物的细胞毒性的IC 50值为nM。具有2-呋喃酰胺侧链的化合物7d在所有这些化合物中显示出最强的细胞毒性,平均IC 50值为6.06 nM。
