PRODUCT INTRODUCTION
description
Topoisomerase-1 Inhibitor LMP744 is an indenoisoquinoline derivative and topoisomerase 1 (Top1) inhibitor, with potential antineoplastic activity. Upon administration, LMP744 binds to and stabilizes cleaved DNA-Top1 complexes, which prevents DNA re-ligation, induces stable, irreversible DNA strand breaks, prevents DNA repair, and leads to cell cycle arrest and apoptosis. As tumor cells proliferate at a much higher rate than normal cells, LMP744 specifically targets cancer cells. Top1, a DNA modifying enzyme essential for transcription, replication, and repair of double-strand DNA breaks, is overexpressed in tumor cells.
