A novel series of C-4β-disulfide/trisulfide-containing podophyllotoxin derivatives were designed, synthesized, and biologically evaluated for their cytotoxic activities against human cancer cell lines, including KB (Mouth Epidermal Carcinoma Cells) and KB/VCR (Vincristine-resistant Mouth Epidermal Carcinoma Cells). Most of these compounds exhibited promising moderate to good cytotoxic activities. In
设计,合成了一系列新的含C-4β-二硫化物/三硫化物的鬼臼毒素衍生物,并对其生物学活性进行了评估,这些衍生物对人类癌细胞系(包括KB(口腔表皮癌细胞)和KB / VCR(耐长春新碱的口腔))具有细胞毒活性。表皮癌细胞)。这些化合物大多数显示出有希望的中等至良好的细胞毒活性。特别地,它们中的一些表现出甚至优于依托泊苷的活性,特别是对于KB / VCR细胞系,表明引入二硫化物/三硫化物部分将有利于克服依托泊苷的多药耐药性限制。此外,进一步对最有希望的化合物进行了代谢评估,结果表明二硫键在人体血浆中可以稳定8小时,体内抗癌活性。
