Product Description
Opnurasib (JDQ-443) (NVP-JDQ443) is an orally potent and specific covalent KRAS G12C inhibitor. Opnurasib has anti-tumor effects.
Biological Activity I Assay Protocols (From Reference)
Targets
KRAS(G12C) (IC50 = 0.012 μM)
ln Vitro
Opnurasib (NVP-JDQ443) inhibits KRAS's GDP-bound inactive conformation[1].
Opnurasib, with IC50 values of 0.018 and 0.063 μM, respectively, promotes the proliferation of the KRASG12C-mutated cell lines NCI-H358 and NCI-H2122, as well as dose-dependent reductions of phosphorylated ERK (pERK) levels[2].
Opnurasib inhibits GDP-bound KRASG12C with low reversible binding affinity to the RAS switch II pocket in a covalent and selective manner. It also prevents the growth of cell lines that are double-mutant for KRAS and KRASG12C, as well as G12C/H95, G12C/R68S, and G12C/Y96[2].
ln Vivo
Opnurasib (10-100 mg/kg, Orally, daily for 14 days) exhibits antitumor activity in KRAS G12C-mutated CDX models[2].
Opnurasib (Orally, 100 mg/kg, daily (JDQ443) + 7.5 mg/kg, twice daily (TNO155), for 36 days) exhibits higher cell growth inhibition or cell killing than does single-agent JDQ443 when combined with TNO155[2].
In PDX models of colorectal tumors and non-small cell lung cancer, opracitasin produces distinct antitumor responses that are enhanced by concurrent treatment with additional agents[2].
Cell Assay
Cell Line: Ba/F3 cells
Concentration: 0, 0.3, 1 μM
Incubation Time: 30 min, 4 h
Result: Inhibited signaling (pERK) and proliferation of the KRAS G12C/H95 double mutants G12C/H95R and G12C/H95Q.
Animal Protocol
KRAS G12C tumor-bearing nude mice (MIA PaCa-2 (PDAC); NCIH2122, LU99, HCC44, NCI-H2030 (NSCLC); and KYSE410 (esophageal cancer))
10, 30, 100 mg/kg
Orally, daily for 14 days

Shipping Condition

Solubility Data
Solubility (In Vitro)
DMSO: ~100 mg/mL (~190.1 mM)
Ethanol: ~100 mg/mL (~190.1 mM)
Solubility (In Vivo)
Solubility in Formulation 1: ≥ 2.08 mg/mL (3.95 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL.
Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution.

Solubility in Formulation 2: ≥ 2.08 mg/mL (3.95 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly.

 (Please use freshly prepared in vivo formulations for optimal results.)
Preparing Stock Solutions 1 mg 5 mg 10 mg
1 mM 1.9010 mL 9.5052 mL 19.0103 mL
5 mM 0.3802 mL 1.9010 mL 3.8021 mL
10 mM 0.1901 mL 0.9505 mL 1.9010 mL

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

Calculator

Molarity Calculator allows you to calculate the mass, volume, and/or concentration required for a solution, as detailed below:

  • Calculate the Mass of a compound required to prepare a solution of known volume and concentration
  • Calculate the Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Calculate the Concentration of a solution resulting from a known mass of compound in a specific volume
An example of molarity calculation using the molarity calculator is shown below:
What is the mass of compound required to make a 10 mM stock solution in 5 ml of DMSO given that the molecular weight of the compound is 350.26 g/mol?
  • Enter 350.26 in the Molecular Weight (MW) box
  • Enter 10 in the Concentration box and choose the correct unit (mM)
  • Enter 5 in the Volume box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
  • Enter 25 into the Volume (End) box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 62.5 μL (0.1 ml) appears in the Volume (Start) box

Molecular Weight Calculator allows you to calculate the molar mass and elemental composition of a compound, as detailed below:

Note: Chemical formula is case sensitive: C12H18N3O4  c12h18n3o4
Instructions to calculate molar mass (molecular weight) of a chemical compound:
  • To calculate molar mass of a chemical compound, please enter the chemical/molecular formula and click the “Calculate’ button.
Definitions of molecular mass, molecular weight, molar mass and molar weight:
  • Molecular mass (or 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.
