Bromfenac Sodium (formerly AHR-10282R; AHR10282R; AHR-10282, AHR10282; trade names Prolensa, Bromday, Xibrom), an approved nonsteroidal anti-inflammatory drug (NSAID), is an orally bioavailable COX-1/2 inhibitor with anti-inflammatory activity. It can inhibit the biosynthesis of prostaglandin by blocking cyclooxygenase 1 and 2.
| ln Vitro |
In HLEC-B3, bromfenac (0-80 μg/mL; 24 h) can block the epithelial-mesenchymal transition triggered by transforming growth factor-β2 in a concentration-dependent way[2]. In human anterior capsules, the transforming growth factor-β2-induced epithelial-mesenchymal transition is inhibited by bromfenac (80 μg/Ml; 48 h)[2].

| ln Vivo |
In rats, bromfenac (0.0032-3.16%; 100 or 200 μL; applied topically) has notable anti-inflammatory effects at doses as low as 0.1% (4 hours before treatment) or 0.32% (18 hours before treatment)[3]. When applied topically to the paws, bromfenac (0.032-3.16%; 100 μL) has dose-dependent anti-inflammatory effects in rats[3]. Applying bromfenac (0.032-1.0%; 50 μL) directly to the skin area of guinea pigs exposed to UV light is 26 times more effective than indomethacin at preventing erythema[3]. The amount of paw volume in both hind limbs of rats is reduced in a dose and time dependent manner when bromfenac (0.0032-0.1%; 50 μL) is rubbed onto the uninjected paw for four hours a day, five days a week[3]. When applied topically to the abdomen, bromfenac (0.32%; 50 μL) significantly inhibits mice's abdominal constriction in response to an ACh challenge[3]. When applied as eyedrops, 1 μL (0.09%) of bromfenac is applied twice daily for four weeks, partially reducing corneal staining, which becomes less noticeable by the fourth week[4].

Cell Viability Assay[2]
Cell Types: transforming growth factor-β2-treated human anterior capsules. Tested Concentrations: 80 μg/mL Incubation Duration: 48 hrs (hours) Experimental Results: Suppressed transforming growth factor-β2-induced epithelial-mesenchymal transition in primary lens epithelial cells (LECs). Cell Migration Assay [2] Cell Types: HLEC-B3 cells Tested Concentrations: 0, 20, 40, 60, and 80 μg/ mL Incubation Duration: 24 hrs (hours) Experimental Results: Suppressed transforming growth factor-β2-induced cell migration in HLEC-B3 cells, and demonstrated inhibition of the over-expression of epithelial-mesenchymal transition markers. |
| Animal Protocol |
Animal/Disease Models: Male SD (Sprague-Dawley) rats (150-250 g) are injected carrageenan[2]
Doses: 0.0032, 0.01, 0.032, 0.1, 0.32, 1.0, 3.16% (100 or 200 μL) Route of Administration: Rubbed onto the backs before 1-72 h of injected carrageenan Experimental Results: Produced significant anti-inflammatory activity when applied 1, 2, and 4 h prior to carrageenan challenge at 0.32%. Applied 1 or 4 h prior to carrageenan challenge was active, but not when applied 24 h (or longer) prior to carrageenan challenge at 0.2%. |

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 1.14 mg/mL (3.20 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 11.4 mg/mL clear DMSO stock solution to 400 μL of PEG300 and mix evenly; then add 50 μL of Tween-80 to the above solution and mix evenly; then add 450 μL of 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: ≥ 1.14 mg/mL (3.20 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 11.4 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. (Please use freshly prepared in vivo formulations for optimal results.) |

| 10 mM | 0.2808 mL | 1.4039 mL | 2.8078 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.
