Background

CP 31398 dihydrochloride is a potent activator of p53 with maximum tolerated dose of 400 ppm [2].

Tumor protein p53 (p53) is a crucial protein in multicellular organisms and plays an important role in preventing cancer formation. Many studies have shown that activated p53 regulates the expression of p21 which binds to the G1-S/CDK complexes (molecules important for the G1/S transition in the cell cycle) and inhibits their activity [1].

CP 31398 dihydrochloride is a potent p53 stabilization and is regarded as a promising agent which combines with chemotherapy drugs for cancer treatment. When tested with a panel of 9 human cancer cell lines, CP 31398 dihydrochloride treatment resulted in cell apoptosis in mutant or wild-type p53 expressed cell lines (SW480, SKBr3, PA1, U20S, HCT116, and Saos-2) and enhanced chemotherapeutic drugs effect on cell killing while had no effect on cell lines not expressed p53 [1]. In four human HNSCC cell lines (JHU-O29, UMSCC-22A and Fadu), administration of CP 31398 dihydrochloride for 96 h inhibited the cell growth by accumulating p53 expression [2].

In colon adenocarcinomas F344 rast model, combination low dose of CP 31398 dihydrochloride with celecoxib markedly suppressed colon adenocarcinoma incidence (78%) and multiplicity (90%) by enhancing the expression of p53 which indicated that a combination of low dose CP-31398 dihydrochloride and celecoxib could be a promising therapy for colon cancer in clinic [3].
