Description: | Pifithrin-?, p-Nitro, Cyclic (PFN-?) is cell-permeable and active-form p53 inhibitor. Pifithrin-?, p-Nitro, Cyclic is one order magnitude more active than Pifithrin-? in protecting cortical neurons exposed to Etoposide (ED50=30 nM). Pifithrin-?, p-Nitro, Cyclic behaves as a p53 posttranscriptional activity inhibitor. Pifithrin-?, p-Nitro, Cyclic do not prevent p53 phosphorylation on the S15 residue[1][2]. |
