Biological Activity
|
KRas G12C |
Opnurasib traps the GDP-bound inactive conformation of KRAS[1].
Opnurasib promotes dose-dependent reductions of phosphorylated ERK (pERK) levels and the proliferation of the KRASG12C-mutated cell lines NCI-H358 and NCI-H2122, with IC50 values of 0.018 and 0.063 μM, respectively[2].
Opnurasib covalently and selectively binds and inhibits GDP-bound KRASG12C with low reversible binding affinity to the RAS switch II pocket, and also inhibits proliferation of KRASG12C-mutated and KRAS G12C/H95, G12C/R68S, and G12C/Y96 double-mutant cell lines[2].

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.
Opnurasib (Orally, 100 mg/kg, daily (JDQ443) + 7.5 mg/kg, twice daily (TNO155), for 36 days) shows greater cell growth inhibition or cell killing compared with single-agent JDQ443 when combined with TNO155[2].
Opnurasib generates categorical antitumor responses in PDX models of NSCLC and colorectal tumors that are improved by combination treatment with other agents[2].

Animal Model:KRAS G12C tumor-bearing nude mice (MIA PaCa-2 (PDAC); NCIH2122, LU99, HCC44, NCI-H2030 (NSCLC); and KYSE410 (esophageal cancer))[2]
-
Dosage:10, 30, 100 mg/kg
-
Administration:Orally, daily for 14 days
-
Result:Inhibited the growth of all models in a dose-dependent manner.
-
Animal Model:Three KRAS G12C-mutated CDX models (LU99, NCI-H2030, and KYSE410)[2]
-
Dosage:100 mg/kg (JDQ443) + 7.5 mg/kg (TNO155)
-
Administration:Orally, daily (JDQ443) or twice daily (TNO155), for 36 days
-
Result:Combined with TNO155, showed either greater tumor efficacy compared with each agent alone (H2030, KYSE410) or a delayed time to tumor progression (LU99).

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.08 mg/mL (3.95 mM); Clear solution
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
