Bioactivity | SAH-SOS1A is a peptide-based SOS1/KRAS protein interaction inhibitor. SAH-SOS1A binds to wild-type and mutant KRAS (G12D, G12V, G12C, G12S, and Q61H) with nanomolar affinity (EC50=106-175 nM), directly and independently blocks nucleotide association, impairs KRAS-driven cancer cell viability, and exerts its effects by on-mechanism blockade of the ERK-MAPK phosphosignaling cascade downstream of KRAS[1]. |
Invitro | SAH-SOS1A (0.625-40 μM) dose-responsively impairs the viability of cancer cells bearing G12D, G12C, G12V, G12S, G13D, and Q61H mutations with IC50 values in the 5- to 15-μM range. Cancer cells expressing wild-type KRAS, such as HeLa and Colo320-HSR cells, are similarly affected[1].SAH-SOS1A (5-40 μM; 4 hours) dose-responsively inhibits MEK1/2, ERK1/2, and AKT phosphorylation[1].
