MRTX1133 is a noncovalent, potent, and selective alkyne-based KRAS G12D inhibitor. MRTX1133 optimally fills the switch II pocket and extends three substituents to favorably interact with the protein, resulting in an estimated KD against KRAS G12D of 0.2 pM. MRTX1133 prevents SOS1-catalyzed nucleotide exchange and/or formation of the KRAS G12D/GTP/RAF1 complex, thereby inhibiting mutant KRAS-dependent signal transduction. MRTX1133 selectively inhibits KRAS G12D mutant, but not KRAS wild-type, tumor cells. MRTX1133 has single digit nanomolar activity in cellular assays and marked in vivo efficacy in tumor models harboring KRAS G12D mutations .

Divarasib (GDC-6036) is an orally active, selective KRAS G12C inhibitor with an IC50 of <0.01 μM. Divarasib covalently binds Cys12 in GDP-bound KRAS G12C, occupies the switch II pocket, blocks GTP binding and SOS-mediated reactivation, and inhibits oncogenic KRAS signaling. Divarasib induces tumor shrinkage and robust tumor growth inhibition in KRAS G12C-positive models and cancer cells. Divarasib can be used for the research of non-small cell lung cancer, colorectal adenocarcinoma, pancreatic ductal adenocarcinoma, and other KRAS G12C-mutated solid tumors .

Divarasib (GDC-6036) adipate is an orally active, selective KRASG12C inhibitor with an IC50 of <0.01 μM. Divarasib adipate covalently binds Cys12 in GDP-bound KRASG12C, occupies the switch II pocket, blocks GTP binding and SOS-mediated reactivation, and inhibits oncogenic KRAS signaling. Divarasib adipate induces tumor shrinkage and robust tumor growth inhibition in KRASG12C-positive models and cancer cells. Divarasib adipate can be used for the research of non-small cell lung cancer, colorectal adenocarcinoma, pancreatic ductal adenocarcinoma, and other KRASG12C-mutated solid tumors .
BI-2852 is a KRAS inhibitor for the switch I/II pocket (SI/II-pocket) by structure-based agent design with nanomolar affinity. BI-2852 is mechanistically distinct from covalent KRASG12C inhibitor (binds to switch II pocket) and binds ten-fold more strongly to active KRASG12D versus KRASwt (740 nM vs 7.5 μM). BI-2852 blocks GEF, GAP, and effector interactions with KRAS, leading to inhibition of downstream signaling and an antiproliferative effect in KRAS mutant cells.
ARS-1323-alkyne is a covalent inhibitor probe that covalently binds to the Switch-II pocket (S-IIP) of the KRAS G12C mutant protein. ARS-1323-alkyne visualizes the covalent modification of KRAS G12C and quantitatively measures the binding efficiency of the inhibitor to the target. ARS-1323-alkyne can be used to validate the target occupancy of KRAS G12C inhibitors and the synergistic mechanism of combination therapy .

MRTX1133 formic is a noncovalent, potent, and selective KRAS G12D inhibitor. MRTX1133 formic optimally fills the switch II pocket and extends three substituents to favorably interact with the protein, resulting in an estimated KD against KRAS G12D of 0.2 pM. MRTX1133 formic prevents SOS1-catalyzed nucleotide exchange and/or formation of the KRASG12D/GTP/RAF1 complex, thereby inhibiting mutant KRAS-dependent signal transduction. MRTX1133 formic shows efficacy in tumor models harboring KRAS G12D mutations .

2C07 is a mutant Ras (K-Ras M72C, H-Ras M72C) inhibitor. 2C07 blocks the activation of PI3K through allosteric Ras modification. 2C07 binds to the modified switch II pocket (S-IIG) of Ras in both GDP- and GTP-bound states, stabilizes the GDP-bound state, disrupts the polar interactions of the canonical GTP-bound state, and inhibits SOS binding and nucleotide exchange. 2C07 can be used in cancer-related research .

KRAS (Kirsten Rat Sarcoma Viral Oncogene Homolog) is one of the most important oncogenic driver genes in oncology, with high mutation frequencies in pancreatic cancer, non‑small cell lung cancer, and colorectal cancer. For a long time, KRAS was considered "undruggable" due to the lack of suitable small‑molecule binding pockets on its protein surface. In recent years, with the discovery of the switch‑II pocket and the successful approval of KRAS G12C inhibitors, KRAS‑targeted research has achieved groundbreaking progress, which has also spurred a wave of development targeting non‑G12C mutants such as G12D and G12V, as well as upstream and downstream regulatory factors including SOS1 and SHP2.
MCE KRAS Targeted Compound Library contains 79 small‑molecule compounds targeting the KRAS, serving as high‑quality research tools for mechanistic studies of KRAS‑mutant tumors, combination therapy development, resistance mechanism exploration, and high‑throughput drug screening, thereby providing robust support for KRAS‑targeted drug discovery.

BBO-11818 is an orally active, highly selective (relative to NRAS and HRAS), non-covalent pan-KRAS inhibitor (IC50=28-120 nM). BBO-11818 specifically binds to the Switch-II/Helix 3 pocket, disrupts the KRAS:RAF1 interaction by inducing conformational changes, and blocks the MAPK signaling pathway. BBO-11818 exhibits significant anti-tumor activity, which not only inhibits cell proliferation and induces apoptosis, but also drives tumor regression in xenograft models. BBO-11818 produces synergistic effects when combined with Cetuximab (HY-P9905), anti-PD-1 antibody or PI3Kα inhibitor. BBO-11818 is used in the research of KRAS mutation-related malignancies such as pancreatic cancer, non-small cell lung cancer and colorectal cancer .
