COA Handling Instructions

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

For research use only. We do not sell to patients.

Description

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

In Vitro

Pifithrin-α, p-Nitro, Cyclic (PFN-α) efficiently blocks p53-triggered cell death and p21/WAF1 expression in cortical neurons exposed to etoposide at concentrations one order magnitude lower than that in PFT-α[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

Intraocular injection of pifithrin-α slightly increases survival of retinal ganglion cell (RGC) at the concentration of 6 μM but not at 0.06 μM. Pifithrin-α, p-Nitro, Cyclic (PFN-α) is not effective in vivo, even at 6 μM[1].
Pifithrin-α, p-Nitro, Cyclic shows the half-life (t1/2) of 6 hours (when incubated in biological conditions)[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
