SAH-SOS1A TFA
Based on 1 Customer Validation
SAH-SOS1A TFA is a peptide-based SOS1/KRAS protein 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-driven cancer cell viability and exerts its effects by on-mechanism blockade of the ERK-MAPK phosphosignaling cascade downstream of KRAS.

KRAS-SOS1 |
KRas G12C 140 nM (EC50) |
KRas G12D 109 nM (EC50) |
KRas G12V 154 nM (EC50) |
KRas G12S 155 nM (EC50) |
KRas Q61H 175 nM (EC50) |
K-Ras WT 106 nM (EC50) |
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].
