ZM484 is a potent dual p53-MDM2/TOP1 inhibitor that exhibits antiproliferative and antitumor activity both in vitro and in vivo. ZM484 effectively upregulates p53 and MDM2 proteins and maintains TOP1 inhibitory activity by the release of camptothecin (CPT) and a potent p53-MDM2 inhibitor. ZM484 induces cell cycle arrest and apoptosis by regulating the expression of key apoptosis- and cycle-related proteins, including caspase-3, Bcl-2, and Cyclin B1. ZM484 can be used for colorectal cancer research[1].
