      Description
      OverviewA cell-permeable pyrazolylsulfonamide compound that activates heat shock factor 1 (HSF1) and protects mammalian cells against stress-induced apoptosis. Offers protection against ER stress-induced apoptosis as indicated by blunting of caspase-3 activity in treated cells. Shown to activate human HSF1 function in yeast cells. Promotes the nuclear localization and phosphorylation of HSF1 (within 2 h of treatment). Activates Hsp25 and Hsp70 expression in wild-type mouse embryonic fibroblasts (~ 30 µM) and Hsp70 in HeLa cells. Shown to directly and reversibly interact with cytosolic chaperonin TRiC/CCT subunit (Kd = 613 nM for HSF1A-FITC and Tcp1), involving the hinge 2 region, and destabilize TRiC/CCT-HSF1 association. However, it does not perturb ATP hydrolysis. Reduces protein misfolding and cell death in PolyQ-expressing neuronal precursor cells and protects against cytotoxicity in Drosophila melanogaster model of PolyQ-mediated neurodegeneration.

      Please note that the molecular weight for this compound is batch-specific due to variable water content. Please refer to the vial label or the certificate of analysis for the batch-specific molecular weight. The molecular weight provided represents the baseline molecular weight without water.
