| Description | Pifithrin-α, p-Nitro, Cyclic (PFN-α) is a cell-permeable, active-form inhibitor of p53. |
| In vitro | Pifithrin-α, p-Nitro, Cyclic (PFN-α) significantly inhibits p53-induced cell death and p21/WAF1 expression in cortical neurons exposed to etoposide, requiring concentrations an order of magnitude lower than PFT-α[1]. |
| In vivo | Intraocular administration of pifithrin-α at a concentration of 6 µM modestly enhances the survival of retinal ganglion cells (RGC), while it remains ineffective at 0.06 µM. Despite the observed in vitro benefits, pifithrin-α, p-Nitro, Cyclic (PFN-α) demonstrates no in vivo efficacy, even at the 6 µM concentration. Furthermore, pifithrin-α, p-Nitro, Cyclic exhibits a half-life (t1/2) of 6 hours under biological conditions[1]. |
