Application

Pifithrin-α has been used:
  • to study the effect of specific p53 inhibitor on p53-upregulated modulator of apoptosis (PUMA) expression after transient global cerebral ischemia (tGCI)
  • as p53 inhibitor to treat PA1 cells
  • as a tumor protein p53 (TRP53) inhibitor, to treat mouse lung epithelial-12 (MLE-12) cells

Biochem/physiol Actions

Pifithrin-α is a reversible inhibitor of p53-mediated apoptosis and p53-dependent gene transcription such as cyclin G, p21/waf1, and mdm2 expression. Pifithrin-α enhances cell survival after genotoxic stress such as UV irradiation and treatment with cytotoxic compounds including doxorubicin, etopoxide, paclitaxel, and cytosine-β-D-arabinofuranoside. Pifithrin-α protects mice from lethal whole body γ-irradiation without an increase in cancer incidence. The protective effect is not seen in p53-null mice or cells expressing a dominant negative mutant of the p53 gene. Protection is conferred by the transient expression of p53 in p53-deficient cell lines.

The p53 protein is traditionally believed to be a tumor suppressor. Activation of p53-dependent apoptosis in response to damage to cell DNA provides for the elimination of possible tumor cell precursors. However, in some cases the activity of p53 can
