NSC290956 is a small molecule inhibitor of KRas with Kd of 21.3 uM.NSC290956 inhibits KRas activity and downstream signaling events in KRas-driven nuytant NSCLC cells, decreases the cellular viability, cell cycle, and migration.NSC290956 changes KRas-dependent metabolic phenotype in Non-small-cell lung cancer cells, regulates mitochondrial dysfunction for apoptosis in both A549 and H358 cells.NSC290956 shows activity in the KRas mutant cell line xenograft.

MRTX-EX185 (EX185) is a novel potent small-molecule inhibitor of KRAS mutants, exhibits target engagement against KRAS(G12D) with IC50 of 90 nM, binds to GDP-loaded KRAS and KRAS(G12D), as well as the active GNP state.MRTX-EX185 also bound GDP-loaded HRAS.MRTX-EX185 engages both nucleotide states-albeit with preference for the inactive GDP-loaded protein-and might present an opportunity to inhibit even constitutively active (GTP-loaded) KRAS hotspot mutants MRTX-EX185 engages numerous KRAS Q61, G12 and G13 mutant proteins and drives antiproliferation.

K-tetracosapeptide (K-TC) is a peptide of 24 amino acids corresponding to the helix a5 in KRAS4B, potent inhibitor of KARATE (KRAS4B-RHOA-mTORC2 Ensemble), specifically targets the KRAS4B-RHOA interaction.

KRpep-2d (Ac-RRCPLYISYDPVCRR-NH2) is a potent, selective, cell-membrane permeable, cyclic peptide inhibitor of K-Ras(G12D) with IC50 of 1.6 nM, >10-fold selectivity over WT and G12C KRas; KRpep-2d significantly suppressed ERK-phosphorylation, downstream of K-Ras(G12D), along with A427 cancer cell proliferation at 30 μM peptide concentration.

K-Ras G12D inhibitor KS-58 is the first K-Ras(G12D) selective, bicyclic peptide inhibitor with binding Ki of 22 nM; KS-58 suppressed growth of A427 cells and PANC-1 cells (human pancreas carcinoma, G12D mutant) down to 21.1% and 50.1% at 30 uM. KS-58 showed significantly weaker cell growth suppression activities against A549 (human lung carcinoma, G12S mutant), H1975 (human lung carcinoma, WT), MIA PaCa-2 (human pancreas carcinoma, G12C mutant), and Capan-1 (human pancreas carcinoma, G12V mutant) cells. KS-58 reduced the phosphorylation of ERK down to 26.0% and 57.6% at 30 uM, respectively. Biotin-KS-58 exhibited stronger binding to K-Ras(G12D) than to other Ras proteins; KS-58 enters cells, binds to both forms of intracellular K-Ras(G12D)GDP/GTP, and inhibits K-Ras(G12D)GDP/GTP-effector protein interactions, thus preventing downstream Ras signal pathways, such as ERK, and suppressing cell proliferation. KS-58 exhibits anti-cancer activity when given as an intravenous injection to mice with subcutaneous or orthotropic PANC-1 cell xenografts.
