Kobe0065 exhibits potent activity to competitively inhibit the binding of H-Ras·GTP to c-Raf-1 RBD with a Ki value of 46 ± 13 μM. Kobe0065 reduced the amount of c-Raf-1 associated with H-Ras G12V in NIH 3T3 cells in a dose-dependent manner, indicating the inhibition of the cellular activity of Ras. Kobe0065 at 20 μM efficiently inhibited the phosphorylation of MEK and ERK, downstream kinases of Raf in NIH 3T3 cells transiently expressing H-Ras G12V, although the effect was slightly weaker than that of 2 μM sorafenib.

|Animal A (mg/kg) = Animal B (mg/kg) multiplied by||Animal B Km|
|Animal A Km|
For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.

MRTX0902 is an effective SOS1 inhibitor with an IC50 of 46 nM.
Gdc-6036 (compound 17A) is an oral covalently mutated KRAS G12C inhibitor with IC50<0.01 μM against K-Ras G12C. The EC50 of GDC-6036 in K-Ras G12C-alkylated HCC1171 cells was 2 nM.
RM-018 is an inhibitor of the active state of KRASG12C. Rm-018 retains the ability to bind and inhibit KRASG12C/Y96D. Rm-018 combines with GTP-bound to activate the [" RAS(ON) "] state of KRASG12C.
HJC0197 is a potent antagonist of Epac1 (the exchange protein directly activated by cAMP 1) and Epac2 (IC50=5.9 μM for Epac2). HJC0197 selectively blocked camp-induced Epac activation. HJC0197 inhibited epAC1-mediated RAP1-GDP exchange activity in the presence of isoconcentration of cAMP.
SAH-SOS1A TFA is a peptide-based SOS1/KRAS protein interaction inhibitor. SAH-SOS1A TFA binds to wild-type and mutant KRAS (G12D, G12V, G12C, G12S, and Q61H) with nanomolar affinity (EC50=106-175 nM) and directly and independently blocks nucleotide association.
