Anwendung

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. Wirkung

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.

The presynaptic proteins MUNC18-1, syntaxin-1, and SNAP25 drive SNARE-mediated synaptic vesicle fusion and are also required for neuronal viability. Their absence triggers rapid, cell-autonomous, neuron-specific degeneration, unrelated to synaptic vesicle deficits. The underlying cell death pathways remain poorly understood. Here

Protein misfolding is a recurring phenomenon that cells must manage; otherwise misfolded proteins can aggregate and become toxic should they persist. To counter this burden, cells have evolved protein quality control (PQC) mechanisms that manage misfolded proteins. Two classes of
