KRAS-IN-62
KRAS-IN-62 is an orally effective pan-KRAS inhibitor that potently inhibits SOS1-mediated KRAS nucleotide exchange (IC50 < 10 nM for KRAS G12D/G12V/G12C/WT). KRAS-IN-62 inhibits pERK signaling and cell proliferation in KRAS-mutant tumor cells (pERK IC90 = 0.51 nM in GP2D cells). KRAS-IN-62 inhibits tumor growth in vivo, with plasma concentrations exceeding IC50 for ~20 h after oral administration in beagle dogs. KRAS-IN-62 can be used in studies of KRAS mutation-related cancers, such as colorectal cancer.

KRAS-IN-62 (Compound 106) exhibits IC50 values of < 10 nM against KRAS G12D, G12V, G12C, and wild-type KRAS in the KRAS G12D SOS1-mediated nucleotide exchange TR-FRET assay[1].
In the active KRAS/CRAF RBD binding assay, Compound 106 shows an IC50 of 10-100 nM for KRAS G12D, and 100-1000 nM for G12V and G12C[1].
KRAS-IN-62 exhibits IC50 values of < 10 nM against KRAS-mutant GP2D (G12D), SW620 (G12V), NCI-H358 (G12C), and KE39 (G12D) cells in the pERK HTRF assay (3 h), with an IC90 of 0.51 nM in GP2D cells, while showing an IC50 of > 1000 nM against wild-type KRAS A375 cells[1].
KRAS-IN-62 shows IC50 values of < 10 nM against multiple KRAS-mutant cell lines in the 3-day proliferation assay[1].
KRAS-IN-62 displays IC90 values of 1.6, 4.2, 1.7, and 10.8 nM for SW620, GP2D, KE39, and NCI-H358 cells, respectively, in the 2D cell viability assay[1].
KRAS-IN-62 displays IC90 values of 6.52, 5.22, 1.18, and 17.88 nM for GP2D, KE39, NCI-H358, and SW620 cells, respectively, in the 3D cell viability assay[1].

Animal Model:Female BALB/c nude mice (6-8 weeks old) received a subcutaneous injection into the right flank with 1×107 GP2D tumor cells in 100 μL DMEM:Matrigel (1:1 ratio). Mice were randomized when tumors reached an average volume of ~300 mm3[1]
-
Dosage:3 mg/kg, 10 mg/kg, 30 mg/kg
-
Administration:Oral gavage (p.o.); single dose
-
Result:Tumor samples were collected at 4 h, 8 h, and 24 h post-administration for pERK immunohistochemical analysis.
Sustained inhibition of ERK phosphorylation (p-ERK) was observed at 4-24 h after a single oral dose.
Plasma concentrations correlated with pERK inhibition in tumor tissue.

Administration:Oral gavage (p.o.); twice a day (BID); 2 weeks
-
Result:Dose-dependently inhibited tumor growth over the 2-week treatment period.
Plasma concentrations of this compound exceeded its IC50 and IC90 for extended periods of time after oral administration.
-
Animal Model:BALB/c nude mice were inoculated subcutaneously into the right flank with 5×106 or 1×107 GP2d colorectal adenocarcinoma (KRAS G12D mutant) cells. Mice were randomized when mean tumor volume reached 300-400 mm3 (n=9 or 12/group)[1]
-
Dosage:3 mg/kg, 10 mg/kg, 30 mg/kg, 60 mg/kg
-
Administration:Oral gavage (p.o.); single dose
-
Result:Inhibited DUSP6 mRNA expression in tumor tissue in a dose- and time-dependent manner.
