Application

Q-VD-OPh hydrate has been used:
  • as a pan-caspase inhibitor to prevent cell death in urothelial carcinoma cells (UCC)
  • to induce canonical caspase-dependent apoptosis in UC cells
  • to block caspase-3 and Poly (ADP-ribose) polymerase-1 (PARP-1)
  • to study the protective role of EspZ effector protein against apoptosis and necrosis in human epithelial cells

Biochem/physiol Actions

Q-VD-OPh is a potent pan-caspase inhibitor that protects cells from capsase-dependent apoptosis. Q-VD-OPh has superior aqueous stability, cell permeability, and efficacy than FMK-based caspase inhibitors and displays no cytotoxic effects alone.
