Elironrasib is an orally active and covalent inhibitor of KRAS^G12C(ON). Elironrasib forms a tri-complex within tumor cells between KRAS^G12C(ON) and cyclophilin A (CypA). Thus, Elironrasib prevents KRAS^G12C(ON) from signaling via steric blockade of RAS effector binding. Elironrasib inhibits ERK signaling and induced apoptosis in KRASG12C-mutant H358 cells. Elironrasib also inhibits the proliferation of KRAS^G12C mutant cells with a median IC₅₀ of 0.11 nM.

: Elironrasib purchased from MedChemExpress. Usage Cited in: Nat Cancer. 2026 Jan;7(1):116-130. [Abstract]; The Bliss sum of synergy scores for the IK-595 combinations with divarasib, sotorasib, adagrasib, and RMC-6291 was calculated from data obtained from 5‑day CTG assays in the Mia‑PACA‑2 cell line using the integrated synergy score algorithm from the online tool ComBenefit. An integrated score > 10 is considered synergistic (results from a single experiment).

: Elironrasib purchased from MedChemExpress. Usage Cited in: Cell. 2024 Oct 31;187(22):6379-6392.e17. [Abstract]; Immunoblot analysis was performed on HeLa cells transiently overexpressing K-Ras or K-Ras(G12C). HeLa cells were transiently transfected, treated with different concentrations of RMC-6291 (1 μM and 10 μM) for 3 h, and blotted for Ras, M-Ras, R-Ras, and Rheb.

In Vivo:

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.

Protocol 1

Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: 2.5 mg/mL (2.47 mM); Suspended solution; Need ultrasonic

This protocol yields a suspended solution of 2.5 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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.
Protocol 2

Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: 2.5 mg/mL (2.47 mM); Suspended solution; Need ultrasonic

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
Protocol 3

Add each solvent one by one: 10% DMSO 90% Corn Oil
Solubility: ≥ 2.5 mg/mL (2.47 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

Help & FAQs

Do most proteins show cross-species activity?
Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
