    Description: K-Ras(G12C) inhibitor 12 is a potent, selective and allosteric inhibitor of oncogenic K-Ras(G12C), the mutated form of K-ras. It binds to K-Ras(G12C) by forming a covalent bond with the 12C cysteine. K-Ras(G12C) exhibited a slight preference for GTP. However, K-Ras(G12C) inhibitor 12 significantly reduced the affinity for GTP and led to the modification of K-Ras(G12C). Also, K-Ras(G12C) inhibitor 12 inhibited SOS-catalysed nucleotide exchange. In H1792 and H358 K-Ras(G12C)-mutant lung cancer cell lines, K-Ras(G12C) inhibitor 12 reduced the association of C-Raf and B-Raf with Ras.

    In Vitro

    In vitro activity: K-Ras(G12C) inhibitor 12 belongs to a series of small molecules, which irreversibly bind to a common oncogenic mutant K-Ras(G12C) and blocks K-Ras(G12C) interactions. Some of them decrease viability and increase apoptosis of G12C-containing cancer cell lines.

    Cell Assay: K-Ras(G12C) inhibitor 12 is a highly effective Ras inhibitor and its EC50 value in H1792 cells is 0.32 μM.It selectively binds to an oncogenic mutant K-Ras(G12C) in a irreversible manner without affecting the activity of wild-type Ras. After treatment with K-Ras(G12C) inhibitor 12, K-Ras(G12C)-mutant cells exhibit decreased viability and increased apoptosis comparing to cells lacking this mutation.
