Abstract

A series of 9-benzylamino acridine derivatives were synthesized as an extension of our discovery of acridine antitumor agents. Most of these acridine compounds displayed good antiproliferative activity with IC50 values in low micromole range and structure-activity relationships were studied. Topo I- and II- mediated relaxation studies suggested that all of our compounds displayed strong Topo II inhibitory activity at 100 μM, while only four exhibited moderate Topo I inhibitory activity. The typical compound 8p could penetrate A549 Cancer cells efficiently. Compound 8p could intercalate within the double-stranded DNA structure and induce DNA damage. Moreover, compound 8p could induce A549 cells Apoptosis through caspase-dependent intrinsic pathway and arrest A549 cells at the G2/M phase.
