Adagrasib (MRTX849) is an orally active and selective covalent inhibitor of KRAS G12C. Adagrasib binds to the GDP state of the inactive conformation of KRAS G12C and inhibits KRAS and its downstream signaling. Adagrasib exhibits inhibitory activity against KRAS G12C mutant tumors.

Sotorasib (AMG-510) is an orally active and selective covalent inhibitor of KRAS G12C. Sotorasib binds to the GDP state of the inactive conformation of KRAS G12C and inhibits KRAS and its downstream signaling. Sotorasib exhibits inhibitory activity against KRAS G12C mutant tumors.

0990CL is an effective heterotrimer Gαi subunit specific inhibitor, which can interact with purified Go± in GDP-bound state, and can block α2AR mediated cAMP regulation. In the cell model, low concentration of 0990CL could partially restore cAMP level, and high concentration of 0990CL (10μM) began to have negative effects on cell viability.

Ran-IN-1 (Compound M36) is an orally active and selective inhibitor of Ran GTPase. It binds allosterically with high specificity to the switch II pocket of GDP-bound Ran (RanGDP), stabilizing its inactive state and reducing the formation of active Ran-GTP. Ran-IN-1 induces apoptosis in epithelial ovarian cancer (EOC) cells and inhibits DNA repair pathways such as homologous recombination (HR) and non-homologous end joining (NHEJ). This compound shows potential for research in epithelial ovarian cancer, particularly in high-grade serous carcinoma.

KRAS inhibitor-42 (compound 8) is an effective USP7 inhibitor that exhibits high affinity for GDP-bound KRASG12D, with a Ki value of 2.7 μM.

KRASG12D-IN-7 is a selective inhibitor of KRASG12D. It exhibits strong binding affinity to KRASG12D in both GDP-bound and GTP-bound states, with Kd values of 1.12 nM and 1.86 nM, respectively. This compound inhibits the proliferation of KRASG12D-bearing AsPC-1 cells with an IC50 of 10 nM and disrupts MAPK signaling. In AsPC-1 cells, KRASG12D-IN-7 induces G0/G1 phase arrest and apoptosis (apoptosis), and significantly suppresses colony formation. The inhibitor is applicable for research on cancers with KRASG12D mutations, particularly pancreatic ductal adenocarcinoma (PDAC).

KRASG12C IN-17 is an orally active covalent inhibitor of KRASG12C, demonstrating potent inhibitory activity in KRASG12C-mutant cancer cells (NCI-H23 IC50 = 0.7 nM; NCI-H358 IC50 = 0.5 nM). It efficiently and irreversibly forms a covalent bond with KRASG12C in both GDP-bound and GMPPNP-bound states, with a modification rate exceeding 96%. KRASG12C IN-17 is applicable for research on KRAS-driven tumors, including colorectal cancer.

KRASG12C IN-18 is an orally active covalent inhibitor of KRASG12C, achieving complete covalent binding to KRASG12C in both GDP- and GMPPNP-bound states. It exhibits significant antiproliferative activity against KRASG12C and its resistant mutations (including KRASG12C/R68S) with an IC50 in the low nanomolar range. KRASG12C IN-18 demonstrates notable in vivo efficacy in KRASG12C-driven solid tumors and KRASG12C/R68S xenograft models, making it applicable for colorectal adenocarcinoma research.

Son of sevenless homolog 1 (Sos1) is a guanine nucleotide exchange factor (GEF) that directs the exchange of Ras-GDP to Ras-GTP by binding to SH3 domains of the growth factor receptor-bound protein 2 (Grb2), leading to the activation of ERK. Ras inhibitory peptide is a synthetic peptide that contains the sequence PVPPR, which corresponds to a region within human Sos1 that interacts with an SH3 domain of Grb2. It specifically blocks the interaction of the GEF with Grb2, preventing an interaction that is essential for Ras activation by receptor tyrosine kinases, including epidermal growth factor receptor.

KRA-533 is an effective KRAS agonist that targets the GTP/GDP binding pocket within the KRAS protein, inhibiting GTP cleavage. This leads to accumulation of the active GTP-KRAS form, promoting apoptosis and autophagic death in cancer cells.

SOS1 activator 1 is an activator of SOS1-mediated nucleotide exchange (Kd: 44 nM).SOS1 is a guanine nucleotide exchange factor that binds to Ras proteins and catalyzes the exchange of GDP for GTP on RAS, resulting in the exchange of GDP originally bound to Ras for GTP.

ARS-853 is an inhibitor of K-RASG12C(IC50 : 2.5 μM), a mutant form of K-RAS that accumulates in the active GTP-bound state in certain cancer cells

Divarasib (GDC-6036) adipate is a selective and highly potent KRAS G12C inhibitor with an impressively low IC 50 value of <0.01 μM, designed for oral administration. It covalently attaches to the switch II (SW-II) pocket in KRAS G12C, irreversibly maintaining the protein in its inactive GDP-bound state [1] [2].

Sotorasib-D7 is a deuterium-labeled version of Sotorasib. Sotorasib (T8684) (AMG-510) is a potent, orally bioavailable, selective covalent inhibitor of KRAS G12C. It locks KRAS G12C in the inactive GDP-bound state and causes regression of locally advanced or metastatic non-small cell lung cancer (NSCLC) with KRAS G12C mutation.
