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.

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

Burkitt's lymphoma is an aggressive B cell lymphoma whose pathogenesis involves mainly c-Myc translocation and hyperexpression, in addition to antigen-independent BCR signaling and, in some cases, EBV infection. As result of BCR signaling activation, the PI3K/AKT/mTOR pathway results constitutively activated
