Biological Activity
Neutrophil elastase inhibitor 4 (compound 4f) is a competitive inhibitor of human neutrophil elastase (HNE) with IC50 of 42.30 nM and Ki of 8.04 nM. It prompts apoptosis in T47D cells and inhibits the proliferation of T47D, RPMI 8226, A549, and HSF cells with respective IC50 values of 21.25, 34.17, 29.93, and 99.11 nM (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.
It is recommended to sonicate at a lower frequency
It is not recommended to store DMSO stock solutions at room temperature. Once the stock solution is prepared, aliquot into single-use volumes and store at −20 °C (or −80 °C for sensitive compounds). Room-temperature storage accelerates chemical degradation and moisture uptake. When ready to use, thaw an aliquot at room temperature, use immediately, and avoid repeated freeze-thaw cycles.
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).
