A series of novel podophyllotoxin derivatives was synthesized by coupling 4β-amino-4′-demethyl-4-desoxypodophyllotoxin (3a) or 4β-amino-4-desoxypodophyllotoxin (3b) with N-substituted 5-formylindole (2a–h). Their structures were identied by spectroscopic techniques. These novel derivatives were evaluated for cytotoxicity in vitro against HepG2 and HeLa cell lines. Compared with etoposide, most of the compounds showed more potent cytotoxicities against two tumor cell lines. Judging from the IC50 values, compound 5n is a promising agent, which is about 15 and 5 times more toxic than etoposide against HepG2 and HeLa cell lines, respectively.
通过将4β-氨基-4′-去甲基-4-去氧鬼臼毒素(3a)或4β-氨基-4-去氧鬼臼毒素(3b)与N-取代的5-甲酰基吲哚(2a-h)偶联,合成了一系列新型鬼臼毒素衍生物。通过光谱技术确定了它们的结构。体外评估了这些新型衍生物对 HepG2 和 HeLa 细胞系的细胞毒性。与依托泊苷相比,大多数化合物对这两种肿瘤细胞株具有更强的细胞毒性。从 IC50 值来看,化合物 5n 是一种很有前途的制剂,它对 HepG2 和 HeLa 细胞株的毒性分别是依托泊苷的 15 倍和 5 倍。
