A small molecule inhibitor of guanine nucleotide exchange factor (GEF) catalytic activity that binds to SOS1 (Kd=14.7 uM) and disrupts GEF-Ras interaction.

A small molecule inhibitor of guanine nucleotide exchange factor (GEF) catalytic activity that binds to SOS1 (Kd=14.7 uM) and disrupts GEF-Ras interaction; dose-dependently disrupts the SOS1-Ras interaction by competitively inhibiting the binding of SOS1cat to GDP-bound H-Ras in a microscale thermophoresis assay; dose-dependently inhibits Ras activation and downstream ERK activation mediated through EGFR-SOS1-Ras-Raf1-MEK-ERK signaling, specifically inhibits wild-type mouse embryonic fibroblast growth but not the growth of oncogenic H-Ras(G12V)-expressing mouse embryonic fibroblasts; inhibits Ras signaling and growth of pancreatic and prostate cancer cells.

Cell Proliferation Assay Cell Line:Mouse embryonic fibroblasts Concentration:0, 40, 60, and 80 μM Incubation Time:3 days Result:Selectively inhibited the growth of mouse fibroblasts, as exerting inhibition against wild-type mouse embryonic fibroblasts but not mouse embryonic fibroblasts expressing carcinogenic H-Ras(G12V).Western Blot AnalysisCell Line:NIH/3T3 cells Concentration:60 μM, 80 μM Incubation Time:2 hours; stimulated with 50 ng/ml EGF for 5 min Result:Inhibited EGF-induced the increase of the level of p-ERK and Ras-GTP.
