General description

A cell-permeable anticancer drug that inhibits the catalytic activity of topoisomerase II (topo II) without damaging DNA or stabilizing DNA-topo II cleavable complexes (IC50 = 20 µM for purified mammalian topo II versus IC50 = ~ 200 µM for topo I). Also induces apoptosis in human leukemic CEM cells through a caspase-3-like protease-dependent mechanism.

Topoisomerase II (Topo II) is essential for mitosis since it resolves sister chromatid catenations. Topo II dysfunction promotes aneuploidy and drives cancer. To protect from aneuploidy, cells possess mechanisms to delay anaphase onset when Topo II is perturbed, providing additional
