Biological Activity

Description Q-VD-Oph (Quinoline-Val-Asp-Difluorophenoxymethylketone) is a potent pan-caspase inhibitor with IC50 ranged from 25 to 400 nM for caspases 1,3,8, and 9. Q-VD-OPh can inhibits HIV infection.
Targets
Caspase-1 [1] Caspase-3 [1] Caspase-8 [1] Caspase-9 [1]
25 nM-400 nM 25 nM-400 nM 25 nM-400 nM 25 nM-400 nM
In vitro Q-VD-OPh （5-100 μM） potently inhibits Actinomycin D-induced DNA laddering and subsequent apoptosis with minimal toxicity in WEHI 231 cells. Q-VD-OPh prevents caspase mediated cleavage of PARP and activation of the major initiator and effector caspases. [2] Q-VD-OPh protects cardiac myocytes from virus-induced apoptosis in vitro. [4]
In vivo Q-VD-OPh inhibits caspase-1 activity, IL-18 protein expression, and neutrophil infiltration during ischemic ARF in mice. [3] In vivo, caspase inhibition by Q-VD-OPh provides protection from virus-induced myocardial injury, with a significant reduction in caspase-3 activity. [4] In TgCRND8 mice, Q-VD-OPh inhibits caspase-7 activation and limits the pathological changes associated with tau, including caspase cleavage. [5]

Protocol (from reference)

Cell Assay:[2]
  • Cell lines

    WEHI-231 cells

  • Concentrations

    ~1000 μM

  • Incubation Time

    4 hours

  • Method

    Caspase inhibitors are added at the indicated concentrations 30 minutes prior to the addition of apoptotic stimuli. Viability and cell number are determined by trypan blue exclusion from three random fields of greater than 200 cells/field. All experiments are performed a minimum of three times.
Animal Study:[3]
  • Animal Models

    C57BL/6 mice

  • Dosages

    ~120 mg/kg

  • Administration

    Intraperitoneal administration
