KRASG12C IN-19

KRASG12C IN-19 is a selective inhibitor of KRASG12C. It exhibits 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 inhibits downstream ERK phosphorylation (IC50= 24.06 nM) . It shows no significant inhibitory activity on KRASG12V and KRASG12D mutant cancer cells (PANC 1, Panc 03.27, AsPC 1, and GP2d cells) with IC50 values greater than 10,000 nM. KRASG12C IN-19 rapidly forms a covalent bond with KRASG12V-GDP, leading to dose-dependent inhibition of the downstream KRAS pathway. This compound is suitable for research on KRASG12C-driven cancers, including non-small cell lung cancer, pancreatic cancer, and colorectal cancer.
