Pifithrin-μ

A cell-permeable sulfonamide that blocks p53 interaction with Bcl-xL and Bcl-2 proteins and selectively inhibits p53 translocation to mitochondria without affecting the transactivation function of p53.

Description

Description générale

A cell-permeable sulfonamide that blocks p53 interaction with Bcl-xL and Bcl-2 proteins and selectively inhibits p53 translocation to mitochondria without affecting the transactivation function of p53. Effectively protects against γ radiation-induced cell death in vitro and animal lethality in vivo. Because Pifithrin-μ targets only the mitochondrial branch of the p53 pathway without affecting the important transcriptional functions of p53, it is superior to Pifithrin-α (Cat. No. 506132) in in vivo studies. Shown to selectively interact with inducible HSP70 and disrupt its functions.
