BI-0252 is an inhibitor of MDM2-p53 (IC50:4 nM). BI-0252 can induce tumor regressions in all animals of a mouse SJSA-1 xenograft. And it concomitant induction of the tumor protein p53 (TP53) target genes and markers of apoptosis.
AM-6761 is a potent inhibitor of the MDM2-p53 interaction. In the SJSA-1 osteosarcoma xenograft model, AM-6761 shows excellent antitumor activity with an ED50 of 11 mg/kg.
