Fifteen derivatives were synthesized from olibergin A, a major isoflavonoid isolated from the stems of Dalbergia stipulacea Roxb. All compounds were evaluated for cytotoxicity against HCT-116, HT-29, MCF-7 and vero cell lines using MTT assay. Cytotoxicity results showed 5-hydroxy-7,2′,4′,5′-tetramethoxyisoflavone (5) was the most active with IC50 values of 19.03 ± 0.70, 10.83 ± 1.65, 12.53 ± 0.70 and
十五种衍生物从 olibergin A 合成,这是一种从Dalbergia stipulacea Roxb 的茎中分离出来的主要异黄酮。使用 MTT 测定评估所有化合物对 HCT-116、HT-29、MCF-7 和 vero 细胞系的细胞毒性。细胞毒性结果显示 5-羟基-7,2',4',5'-四甲氧基异黄酮 ( 5 ) 对 HCT- 的 IC 50值为 19.03 ± 0.70, 10.83 ± 1.65, 12.53 ± 0.70 和 13.53 ± 0.84 μM。 116、HT-29、MCF-7 和 vero 细胞系。应该指出的是,5-羟基-7,2',4',5'-四甲氧基异黄酮 ( 5 ) 对维罗细胞的毒性比顺铂标准品低两倍 (IC 50 = 6.55 ± 0.81 μM),而5顺铂对 MCF-7 细胞系表现出几乎相同的细胞毒性。5,7,2',4',5'-五甲氧基异黄酮 ( 10 )
