Biological Activity
2-O-Ethyl PAF C-16, a homolog of Platelet-activating Factor (PAF) and competitive ligand for the Platelet-activating Factor Receptor (PAFR), inhibits the binding of PAF antagonist WEB 2086 to PAFR with an IC50 of 21 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.
Use a bath-type ultrasonic cleaner rather than a high-intensity ultrasonic disruptor. Bath sonicators provide gentle, uniform agitation appropriate for dissolving solid compounds without generating cavitation damage or excessive heat. Ensure the solvent tube is fully submerged and use short sonication pulses of 5–10 seconds.
For normal mice, the concentration of DMSO should be kept below 10%. For nude mice, transgenic mice, or mice with weak tolerance, the concentration of DMSO should be kept below 2%. For inhibitors being used for the first time, it is recommended to perform a solvent-negative control experiment to confirm that the solvent has no nonspecific effects on the animals.
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).
