Biological Activity

H203 is a potent dual Mdm2/MdmX inhibitor with Ki of 2/11 nM, respectively.
H203 significantly reduced cell viability in the cells overexpressing both Mdm2 and MdmX, and a significant and dose-dependent decrease in cell number in H203-treated cells lacking Mdm2 or MdmX.
H203-mediated decrease in cell viability is strictly p53-dependent and H203 affects MdmX more specifically than nutlin-3a.
H203 induced the expression of the p21 gene but not the p53 gene in treated cancer cells.
