Application

KNK437 has been used:
  • as a heat shock factor 1 (HSF1) inhibitor to study its effects on the inhibition of viability and apoptosis activation in chemoresistant mice cells
  • as an HSF1 inhibitor to study its effects on viability and apoptosis of colorectal cancer cells
  • as a heat shock protein 70 (HSP70) inhibitor to study its effects on glutamine-induced HSP70 and inflammatory mediator release

Biochem/physiol Actions

KNK437 inhibits the accumulation of heat shock proteins (including hsp -27, -40, -70, -72 and -105). KNK437 inhibits thermotolerance in cells with greater potency than quercetin.
KNK437 is a benzylidene lactam compound.
