Biological Activity
ONO-AE3-208 is an EP4 receptor antagonist with a Ki of 1.3 nM, exhibiting less potent activity against EP3, FP, and TP receptors (Ki values of 30, 790, and 2,400 nM, respectively), while showing no effect on other prostanoid receptors. In wild type mice, treatment with ONO-AE3-208, in conjunction with 3% dextran sodium sulfate, results in severe colitis characterized by epithelial loss, crypt damage, and inflammation, thereby mimicking the effects of EP4 deletion. Further, this compound has been utilized to investigate the role of EP4 signaling in various biological contexts, including immune and autoimmune responses, inflammation, and cancer.
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 at standard cleaning frequency (37–40 kHz). Bath sonication is gentler than a probe sonicator and avoids sample overheating. Sonicate in 5–10 second intervals, checking solubility between pulses, for no more than 2–3 minutes total. Warm the bath to 37 °C if solubility remains poor.
Insoluble impurities, which do not affect the product activity, are recommended to filter out or remove. We will investigate to confirm whether the impurity was introduced during packaging or if it is inherent to the product itself.
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
