p53 reactivator

Roslin 2 bromide (Benzylhexamethylenetetramine bromide) is a p53 reactivator that disrupts the binding of FAK and p5, exhibiting anticancer effects.

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.

PRIMA-1 (NSC-281668) is a mutant p53 reactivator that induces apoptosis and inhibits the growth of human tumors with mutant p53.

SLMP53-2 is a mutant p53 reactivator that restores the wild-type-like conformation and DNA-binding ability of mutp53-Y220C through enhanced interaction with Hsp70, thereby reinstating p53's transcriptional activity. This compound induces cell cycle arrest, apoptosis, and endoplasmic reticulum (ER) stress, displaying antitumor activity [1] [2].

Rezatapopt (PC14586) is a small molecule p53 reactivator with anti-tumor activity that selectively binds to the cleft present in the TP53 Y220C mutant protein and restores the p53 wild-type (normal) conformation and transcriptional activity, and can be used to study locally advanced or metastatic solid tumors.
