A rational design strategy of the novel topoisomerase II inhibitors for the synthesis of the 4-O-(2-pyrazinecarboxylic)-4'-demethylepipodophyllotoxin with antitumor activity by diminishing the relaxation reaction of topoisomerase II-DNA decatenation.

Abstract

A rational design strategy of the novel podophyllum topoisomerase II (Topo II) inhibitors for the synthesis of the esterification and amidation substituted 4'-demethylepipodophyllotoxin (DMEP) derivates was developed in order to discover the potential antitumor prodrug. Firstly, according to the structure-activity relationship, drug combination principle… (More)
