Target: K-Ras(G12C)

IC50: N/A

K-Ras(G12C) inhibitor 9 is an allosteric inhibitor of oncogenic K-Ras(G12C) [1]. Ras proteins belong to the large family of GTPase enzymes which are essential to transduce extracellular signals into diverse cellular responses including proliferation, differentiation, and apoptosis. About 30% of all human cancers contain activating Ras mutations, making them one of the most common known genetic molecular drivers of cancer [2]. Therefore, K-Ras signaling have potential therapeutic advantages in cancer. K-Ras(G12C) is present in roughly 10–20% of Ras-driven cancers and in an estimated 50% of Ras-mutated lung adenocarcinomas [3].

In vitro: K-Ras(G12C) inhibitor 9 belongs to a series of small molecules, which irreversibly compete with GTP and GDP for binding to a common oncogenic K-Ras(G12C) mutant and blocked the association of B-Raf and C-Raf with K-Ras(G12C). K-Ras(G12C) inhibitor 9 (10 μM) decreased viability and increased apoptosis of G12C mutations-containing lung cancer cell lines (H1792, Calu-1, H358, and H23) [1].
