Biological Activity

Description Q-VD-Oph is a potent pan-caspase inhibitor with IC50 ranged from 25 to 400 nM for caspases 1,3,8, and 9.
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

Cell Research:[2]
+ Expand
  • 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 Models: C57BL/6 mice
  • Formulation: DMSO
  • Dosages: ~120 mg/kg
  • Administration: Intraperitoneal administration
    (Only for Reference)

Bio Calculators

Molarity Calculator

Molarity Calculator

Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:

Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)

*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).

Dilution Calculator

Dilution Calculator

Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:

Concentration (start) x Volume (start) = Concentration (final) x Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )

Definitions of molecular mass, molecular weight, molar mass and molar weight:

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
