Amfenac Sodium monohydrate (AHR 5850; AHR5850; AHR5850), the sodium salt of amfenac which is an NSAID, is a non-steroidal analgesic anti-inflammatory agent with antipyretic and analgesic activities. It acts as an inhibitor of COX-1 and COX-2 enzymes with IC50s of 15.3 and 20.4 nM, respectively. Amfenac is transformed in vivo to the active metabolite nepafenac which is also a non-steroidal anti-inflammatory drug (NSAID).
| ln Vitro |
The rate of cell proliferation is higher in transfected COX-2-expressing cells than non-transfected ones. All cell lines exhibit a considerable reduction in proliferation rate upon the addition of Amfenac Sodium Hydrate. The addition of melanoma conditioned media inhibits the generation of nitric oxide by macrophages; this inhibition is somewhat alleviated by the addition of amfenac sodium hydroxide[1]. The findings indicate that Amfenac Sodium Hydrate prevents B-glucuronidase from being released: in the presence of 10 -8 and 10-7 M FMLP, respectively, 5×10-4 M Amfenac Sodium Hydrate prevents the release of the enzyme by 35.3 and 16.3%, respectively. After 16 minutes of incubation with 10-8 M FMLP, the aggregation of polymorphonuclear leukocytes (PMNs) is inhibited by 28.3% upon the addition of 10-4 M Amfenac Sodium Hydrate[2].

Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples.
Injection Formulations
Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 ：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).

Injection Formulation 4: DMSO : 20% SBE-β-CD in saline = 10 : 90 [i.e. 100 μL DMSO → 900 μL (20% SBE-β-CD in saline)] Oral Formulations
Oral Formulation 1: Suspend in 0.5% CMC Na (carboxymethylcellulose sodium) Oral Formulation 2: Suspend in 0.5% Carboxymethyl cellulose Example: Take the Oral Formulation 1 (Suspend in 0.5% CMC Na) as an example, if 100 mL of 2.5 mg/mL working solution is to be prepared, you can first prepare 0.5% CMC Na solution by measuring 0.5 g CMC Na and dissolve it in 100 mL ddH2O to obtain a clear solution; then add 250 mg of the product to 100 mL 0.5% CMC Na solution, to make the suspension solution (2.5 mg/mL, ready for use in animals).

Oral Formulation 3: Dissolved in PEG400 (Please use freshly prepared in vivo formulations for optimal results.) |
| Preparing Stock Solutions | 1 mg | 5 mg | 10 mg | |
| 1 mM | 3.3867 mL | 16.9337 mL | 33.8673 mL | |
| 5 mM | 0.6773 mL | 3.3867 mL | 6.7735 mL | |
| 10 mM | 0.3387 mL | 1.6934 mL | 3.3867 mL |
*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.
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation:：Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
