| In vitro study | Pifithrin-α acts on ConA cells to inhibit p53-dependent transcription of p53 responsive genes. Pififrin-α (10 μm) inhibited Dox, Etoposide, Taxol, and Cytosine arabinoside-induced apoptosis in C8 cells. Pifithrin-α inhibits p53-dependent growth arrest of human diploid fibroblasts formed as a result of DNA damage without any effect on p53-deficient fibroblasts. Pifithrin-α can regulate the nuclear input or output of p53 (or both), and can also reduce the stability of nuclear p53. Pifithrin-α (100-200 nM) acts on hippocampal cells and completely inhibits the increase of p53 DNA binding level and p53 response gene Bax induced by Camptothecin. Pifithrin-α also reduced the level of p53 DNA-binding activity. Pififrin-α (200 nM) protects cultured hippocampal neurons from DNA damaging agent-induced death. Pifithrin-α(200 μm) stabilizes mitochondrial function, inhibits caspase activation, and protects cultured hippocampal neurons from glutamate and β-amyloid peptide-induced death. Pifithrin-α inhibits heat Shock and glucocorticoid receptor signaling, but does not affect NF-κB signaling. Pififrin-α (10 μm) reduces the activation of heat Shock transcription factor (HSF1) and enhances the sensitivity of cells to heat. Pififrin-α (10 μm) acts on HeLa cells, reduces the activation of glucocorticoid receptors, and protects the mouse thymus from dexamethone-induced apoptosis. Pifithrin-α acts on human embryonic kidney cells to inhibit p53-mediated induction of p21/Waf-1. Pifithrin-α shifts the dexamethone dose response curve to the left by increasing the intracellular dexamethone concentration. pifithrin-α acts on ConA cells to inhibit p53-dependent p53 responsive gene transcription.

| In vivo study | Mice (C57BL and Balb/c) were intraperitoneally injected with 2.2 mg/kg of pifihrin-α to completely protect mice from 60% gamma irradiation (8 Gy for C57BL mice), balb/c mice were 6 Gy). Mice injected with pifithrin-α lost less weight than irradiated mice treated without pifithrin-α. Whole-body gamma-irradiated mice were treated with pifithrin-α (2.2 mg/kg) to abrogate the p53-dependent regulation of DNA replication. Treatment of mice with middle cerebral artery occlusion with pifithrin-α(2 mg/kg, I. P.) reduced ischemic brain damage and protected hippocampal neurons from toxic damage 30 minutes later. Treatment of mice with pifithrin-α(3.6 μg/kg, I. P.) inhibited Dex-Induced thymic degeneration. Pifithrin-α(2 mg/kg) treatment of rats with transient middle cerebral artery occlusion significantly reduced the extent of dyskinesia compared to the control group. After the onset of stroke, one hour after the administration of pifithrin-α, the animal had decreased dyskinesia and decreased infarction. After 7 days of treatment with pifithrin-α, the dyskinesia score of the rats was significantly reduced compared to the blank control group. By Tunel and caspase 3 staining, it was observed that pifithrin-α significantly reduced apoptosis in rats. pifithrin-α was administered intraperitoneally at a dose of 2.2 mg/kg to mice (C57BL and Balb/c), mice of both strains were completely protected from the killing dose of 60% gamma irradiation (8 Gy for C57BL mice and 6 Gy for Balb/c mice). Mice injected with pifithrin-α lost less weight than irradiated mice treated without pifithrin-α. Whole-body gamma-irradiated mice were treated with pifithrin-α (2.2 mg/kg) to abrogate the p53-dependent regulation of DNA replication.
