Biological Activity
FXIa-IN-9 (compound 3f) is a potent, selective inhibitor of FXIa, demonstrating strong binding affinity through hydrogen bond formation (human FXIa K i : 0.17 nM, rabbit FXIa K i : 0.5 nM). It exhibits anticoagulant properties, making it valuable for research into thromboembolic conditions, including atrial fibrillation, stroke, myocardial infarction, deep vein thrombosis, and pulmonary embolism (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.
Generally, for molecules that require light-protected storage, we will ship them in amber glass bottles.
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
To quote quickly, tell us: compound name + CAS/structure (SMILES or mol file), intended assay context, solvent preference, salt/stereochemistry requirements, purity/QC level, and the amount (mg–g).
