Elironrasib
Based on 3 publication(s) in Google Scholar
Elironrasib is an orally active and covalent inhibitor of KRASG12C(ON). Elironrasib forms a tri-complex within tumor cells between KRASG12C(ON) and cyclophilin A (CypA). Thus, Elironrasib prevents KRASG12C(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 KRASG12C mutant cells with a median IC50 of 0.11 nM.

The MEK-RAF molecular glue IK-595 has potent antitumor activity across RAS/MAPK pathway-altered cancers. [Abstract]2026 Jan;7(1):116-130. PMID: 41482524
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).

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: 2.5 mg/mL (2.47 mM); Suspended solution; Need ultrasonic
