Biological Activity
SHY-855 (SHY855) is a potent, non-covalent small molecule inhibitor of pan-Ras superfamily, competes with GTP binding to K-Ras WT, the G12D, G12C and Q61H mutants, as well as Rac-1 and Rho-A, with IC50 values of 2.5-5 uM.
SHY-855 robustly inhibits GTP binding to the K-Ras variants.
SHY-855 inhibits phosphorylation and activation of MEK, Erk1/2 and Akt in PANC-1, MIA PaCa-2 and NCI-H1975 cell lines with IC50 of 1-3 uM.
SHY-855 prevent Ras-GTP complex formation with IC50 of 2-3 uM in PANC-1, MIA PaCa-2 and NCI-H1975 cells in Ras pull-down assays.
SHY-855 bind directly to the GTP-binding site of Ras.
SHY-855 inhibits cellular proliferation with IC50 of 0.45-1.2 uM in PANC-1, MIA PaCa-2, NCI-H1975), BxPC3 (K-Ras WT) and A549 (K-Ras G12S mutant) and NCI-H1299 (N-Ras Q61K mutant).
