Bis-naphthalimides: a new class of antitumor agents.

Abstract

A series of bis-intercalators bearing the 1,8-naphthalimide chromophore has been synthesized and in vitro activities determined. Most compounds have higher activities in HT-29 than the leader compounds Mitonafide and Amonafide. One of them (22) was selected for in vivo studies and presents an interesting activity in MX-1 and OVCAR models. (22) also acts as antitopoisomerase II.
