Sotorasib (AMG-510) is a first-in-class, orally bioavailable, and selective KRAS G12C covalent inhibitor. Sotorasib irreversibly inhibits KRAS G12C by locking it in an inactive GDP-bound state. Sotorasib leads to the regression of KRAS G12C‑mutated locally advanced or metastatic non‑small cell lung cancer (NSCLC)^{[1][2][3][4][5][6]}.

In cellular assays, Sotorasib (AMG-510) covalently modifies KRAS G12C and inhibits KRAS G12C signaling as measured by phosphorylation of ERK1/2 (p-ERK) in all KRAS p.G12C-mutant cell lines^[2].
Sotorasib (AMG-510; 1-10 μM; 72 hours) also potently impairs cellular viability in both NCI-H358 and MIA PaCa-2 with IC₅₀≈0.006 μM and 0.009 μM, respectively. Non-KRASG12C lines are insensitive to Sotorasib (IC₅₀>7.5 μM)^[3].
Sotorasib (AMG-510) (0-50 μM, 72 h) inhibits cell growth and has a synergistic effect with Cisplatin (HY-17394) in H23 and H358 cells^[5].
Sotorasib (AMG-510) (100 nM, 4-72 h) has sustained suppression against active KRAS, but still observes adaptive feedback reactivation of RAS-MAPK^[6].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In preclinical tumor models, Sotorasib (AMG-510) rapidly and irreversibly binds to KRAS G12C, providing durable suppression of the mitogen-activated protein kinase (MAPK) signaling pathway. Sotorasib (orally; once daily) is capable of inducing tumor regression in mouse models of KRAS G12C cancer^[3].
Sotorasib (AMG-510) (30 mg/kg; p.o.; daily for 28 days) reduces tumor size in NCI-H358 cell-derived xenografts mice model, and has a synergistic effect with Cisplatin^[5].
