Zaltoprofen (CN 100; CN-100; CN100), a nonsteroidal anti-inflammatory drug (NSAID), is a potent inhibitor of COX-1 and COX-2 enzymes with potential anti-inflammatory activity. It has been approved for treatment of arthritis. It acts by binding to specific sites on the bradykinin B2 receptor. Zaltoprofen most potently inhibits bradykinin-enhancement of capsaicin-induced Ca2+ uptake into DRG neurons. Zaltoprofen also significantly inhibits bradykinin-induced 12-lipoxygenase (12-LOX) activity and the slow bradykinin-induced onset of substance P release from DRG neurons.
| ln Vitro |
In human platelets, thromboxane B2 generation is inhibited in a dose-dependent manner by Zaltoprofen (0.1-10 μM; 15 min)[1]. Zaltoprofen (0.01-1 μM; 30 min) decreases the synthesis of prostaglandin E2 by synovial cells activated by interleukin-1β[1]. The increase in [Ca2+]i in DRG cells caused by bradykinin is inhibited by zaltoprofen (0.1–1 μM; 5 min)[2].

|---|---|
| ln Vivo |
In rats, zaltoprofen (5–20 mg/kg; single po) suppresses nociceptive responses elicited by bradykinin[2]. In mice, acetic acid-induced writhing response is inhibited in a dose-dependent manner by Zaltoprofen (3-30 mg/kg; single po)[2].
|
| Animal Protocol |
Animal/Disease Models: Eightweeks old male Wistar rats were injected Bradykinin every 15 min[2]
Doses: 5, 10, 20 mg/kg Route of Administration: A single po Experimental Results: Inhibited bradykinin-induced nociceptive responses, with an ED50 of 9.7 mg/kg. The duration of analgesic effect was 60-90 min. |

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (8.38 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.5 mg/mL (8.38 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. View More
Solubility in Formulation 3: ≥ 2.5 mg/mL (8.38 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
