SAH-SOS1A TFA is a peptide-basedSOS1/KRASprotein interaction inhibitor. SAH-SOS1A TFA binds to wild-type and mutant KRAS (G12D, G12V, G12C, G12S, and Q61H) with nanomolar affinity (EC₅₀=106-175 nM). SAH-SOS1A TFA directly and independently blocks nucleotide association. SAH-SOS1A TFA impairs KRAS-drivencancercell viability and exerts its effects by on-mechanism blockade of the ERK-MAPK phosphosignaling cascade downstream of KRAS^[1].

SAH-SOS1A TFA (0.625-40 μM; 24 hours) 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 TFA (5-40 μM; 4 hours) dose-responsively inhibits MEK1/2, ERK1/2, and AKT phosphorylation^[1].

SAH-SOS1A (0.2 μL of 10 mM solution; injection; 48 hours; abdomens ofD. melanogasterRas85D^V12/ActinGS) treatment notably decreases the phosphorylation state of ERK1/2^[1].
