Description

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.
