Biological Activity
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 ( EC 50 =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 (1) .
Safety & Regulatory
For Research Use Only (RUO). Not for therapeutic, diagnostic, or clinical use. Wear appropriate PPE and consult the Safety Data Sheet (SDS) prior to handling.
Most small molecule inhibitors are not compatible with autoclaving (121 °C), which can cause thermal decomposition or loss of biological activity. For sterile cell-based experiments, filter-sterilize working solutions through a 0.2 µm membrane after dilution into aqueous buffer. Verify thermal stability in the DataSheet before applying any heat treatment.
When solubility is listed as < 1 mg/mL, the compound dissolves to less than 1 mg per milliliter in water at 25 °C, pH 7.4. Such compounds require an organic co-solvent such as DMSO to prepare a concentrated stock, which is then diluted into aqueous assay buffer. For cell-based assays, keep the final DMSO concentration below 0.1% (v/v) to avoid solvent-induced cytotoxicity.
Need this compound in a format that drops straight into your assay? We can tailor formulation, chemistry, and documentation so your results stay consistent across runs and re-orders.
- Format options: solid or pre-dissolved solution (choose solvent), target concentration, aliquots, light/moisture-protected packaging
- Chemistry options: free base/acid vs salt forms, hydrate/solvate preference, stereoisomer control (single enantiomer or racemate), close analogs
- Add-on labels & handles: D/¹³C/¹⁵N isotopes (LC-MS/internal standards), azide/alkyne or other functional handles for conjugation
- QC & documentation: standard COA or enhanced analytical pack (HPLC/LC-MS/NMR), chiral purity, residual solvents, water content (KF), method-specific specs
- Scale & continuity: mg to gram scale, bulk pricing, lot reservation, repeat-order continuity
