A series of novel conjugates of podophyllotoxin and 5-FU were designed using association strategy and were synthesized by coupling 4′-demethylepipodophyllotoxin with 5-FU-N1-alkyl amino acid ester. These derivatives have been evaluated for cytotoxicity in vitro against tumour cell lines (HL-60, K562, A-549 and AGS), and their octanol–water partition coefficients (log P) were also determined. As compared with VP-16, most compounds showed superior water solubility, as well as more potent inhibitions against these four tumour cell lines. Compound 21 showed interaction with calf thymus DNA, and it was relatively resistant to metabolism by human plasma.
The novel conjugates 10–21 showed superior or comparable inhibitions against HL-60, K562, A-549 and AGS to VP-16, and better water solubility. Compound 21 also showed interaction with calf thymus DNA, and was stable in human plasma.Figure optionsDownload as PowerPoint slide
