Synthesis and anti-tumor activity evaluation of novel podophyllotoxin derivatives

摘要

In order to investigate the effects on the cytotoxicity of indole-3-oxalylamino podophyllotoxin analogs, seven novel podophyllotoxin derivatives were synthesized.The compounds were tested against Hela, K562 or K562/A02 cancer cells in vitro,four of which showed significant cytotoxicity.Among them 9a,9b and 9c were superior to the positive control VP-16.
