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.
p53 tumor suppressor fragment (232-240) is a peptide with the sequence H2N-Lys-Tyr-Met-Cys-Asn-Ser-Ser-Cys-Met-OH, MW= 1066.3. p53 is a tumor suppressor protein that in humans is encoded by the TP53 gene. p53 is crucial in multicellular organisms, where i
