KRASG12C IN-17
KRASG12C IN-17 is an orally active covalent KRASG12C inhibitor, showing strong inhibitory activity in KRASG12C-mutant cancer cells (NCI-H23 IC50 = 0.7 nM; NCI-H358 IC50 = 0.5 nM). KRASG12C IN-17 covalently and irreversibly binds to KRASG12C with > 96% modification efficiency in both GDP-bound and GMPPNP-bound conformations. KRASG12C IN-17 can be used for studies of KRAS-driven cancers, including colorectal cancer.

KRas G12C |
KRASG12C IN-17 (compound 19) potently inhibits KRASG12C-mutant NCI-H23 and NCI-H358 cells with IC50 values of 0.7 nM and 0.5 nM, respectively , following 72-144 hours of incubation[1].
KRASG12C IN-17 covalently modifies KRASG12C in both GDP- and GMPPNP-bound states with >96% conjugation efficiency within 15 minutes[1].
KRASG12C IN-17 inhibits multiple resistance-associated KRASG12C variants, including R68S, H95Q, Y96C and Q99L, in Ba/F3 cells[1].
KRASG12C IN-17 exhibits antiproliferative activity against selected KRASG12C secondary-mutation cancer cell lines, retaining strong potency particularly against Y96C and Q99L variants[1].
