Pifithrin mu

Pifithrin mu selectively interacts with HSP70, disrupting its association with co-chaperones and substrate proteins. It inhibits p53 binding to mitochondria by reducing its affinity for antiapoptotic proteins Bcl-2 and Bcl-XL. This dual action promotes apoptosis and modulates stress response pathways. In neurodegenerative research, Pifithrin mu is used to study protein folding, mitochondrial integrity, and apoptotic regulation.
