Beschreibung

Application

Pifithrin-μ has been used:

• to treat microglial cell line to analyse its neuroprotective effect on M1-like and M2-like phenotype
• as heat shock protein (HSP)-70 inhibitor, to treat transfected Marc-145 cells
• to inhibit heat shock cognate 70 (Hsc70) to elucidate heat shock chaperones mouse embryonic stem cells

Biochem/physiol Actions

Pifithrin-μ is an inhibitor of p53 binding and anti-apoptotic, which directly inhibits p53 binding to mitochondria as well as to Bcl-xL and Bcl-2 proteins.

Pifithrin-μ is an inhibitor of p53 binding and anti-apoptotic, which directly inhibits p53 binding to mitochondria as well as to Bcl-xL and Bcl-2 proteins. PFTμ rescues cells from lethal γ-irradiation-induced cell death. Because pifithrin-μ shuts down only the p53-mitochondrial pathway without affecting the transcriptional functions of p53, it is superior to pifithrin-α.

Pifithrin-μ(PFT-μ) has neuroprotective capabilities against cell death in a preclinical model of hypoxia-ischemia (HI)-induced neonatal encephalopathy. It inhibits nuclear factor-ΙB (NF-ΙB) pathway by inhibiting the interaction of molecular chaperone heat shock protein (HSP)-70 with its substrates.
