KRASG12C IN-19 is a selective and orally active KRASG12C inhibitor. KRASG12C IN-19 exerts potent antiproliferative activity against the KRASG12C-mutant non small cell lung cancer (NSCLC) cell line H358 with an IC50 of 7.6 nM, and effectively suppresses downstream ERK phosphorylation (IC50 = 24.06 nM). KRASG12C IN 19 has no significant inhibitory activity against KRASG12V and KRASG12D-mutant cancer cells (PANC 1, Panc, AsPC 1, and GP2d cells) with IC50 > 10,000 nM. KRASG12C IN-19 rapidly forms a covalent bond with KRASG12V-GDP, leading to dose-dependent inhibition of the downstream KRAS pathway. KRASG12C IN 19 can be employed for research in KRASG12C driven cancers, including non small cell lung cancer, pancreatic cancer, and colorectal cancer.
