SAH-SOS1A is a peptide-based inhibitor targeting the SOS1/KRAS protein interaction. It binds with nanomolar affinity (EC50 = 106-175 nM) to both wild-type and various mutant forms of KRAS, including G12D, G12V, G12C, G12S, and Q61H. By directly obstructing nucleotide association, SAH-SOS1A interferes with KRAS-driven cancer cell viability and inhibits the ERK-MAPK phosphosignaling cascade downstream of KRAS, making it a valuable tool for cancer research and therapeutic exploration.
