别名

Merbarone - CAS 97534-21-9 - Calbiochem,5-(N-Phenylcarboxamido)-2-thiobarbituric Acid, NSC-336628

一般描述

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.
