Molecular Weight 513.49 CAS No. 1135695-98-5
Solubility (25°C)* In vitro DMSO 100 mg/mL (194.74 mM)
Ethanol 100 mg/mL (194.74 mM)
Water Insoluble
In vivo (Add solvents to the product individually and in order)
Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O
5.0mg/ml Taking the 1 mL working solution as an example, add 50 μL of 100 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to make it clear; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

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
