Beschreibung

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.

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