p53

P53R3 is a potent reactivator of p53, effectively restoring sequence-specific DNA binding to several p53 hot spot mutants, namely p53 R175H, p53 R248W, and p53 R273H. This compound exhibits p53-dependent antiproliferative effects with significantly higher specificity compared to PRIMA-1 and promotes the recruitment of both wild-type p53 and p53 M237I to various target gene promoters. Additionally, P53R3 markedly increases the mRNA, total protein, and cell surface expression of death receptor 5 (DR5), demonstrating its utility in cancer research.
