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.

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.

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.

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

KRA-533, a potent KRAS agonist, directly targets the GTP/GDP binding pocket within the KRAS protein, inhibiting GTP cleavage. This inhibition leads to the buildup of constitutively active GTP-bound KRAS, which subsequently activates both apoptotic and autophagic cell death pathways specifically in 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].

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.

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.
