Bromfenac
Bromfenac is a potent and orally active inhibitor of COX, with IC50s of 5.56 and 7.45 nM for COX-1 and COX-2, respectively. Bromfenac can be used in ocular inflammation research.

Human COX-1 5.56 nM (IC50) |
Human COX-2 7.45 nM (IC50) |
Bromfenac (0-80 μg/mL; 24 h) can inhibit transforming growth factor-β2-induced epithelial-mesenchymal transition in HLEC-B3 in a concentration-dependent manner[2].
Bromfenac (80 μg/mL; 48 h) inhibits transforming growth factor-β2-induced epithelial-mesenchymal transition in human anterior capsules[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Cell Line:Transforming growth factor-β2-treated human anterior capsules
-
Concentration:80 μg/mL
-
Incubation Time:48 hours
-
Result:Suppressed transforming growth factor-β2-induced epithelial-mesenchymal transition in primary lens epithelial cells (LECs).
-
Cell Line:HLEC-B3 cells
-
Concentration:0, 20, 40, 60, and 80 μg/mL
-
Incubation Time:24 hours
-
Result:Suppressed transforming growth factor-β2-induced cell migration in HLEC-B3 cells, and exhibited inhibition of the over-expression of epithelial-mesenchymal transition markers.
Bromfenac (0.032-3.16%; 100 μL; rubbed onto the paws) produces dose-related anti-inflammatory activity in rats[3].
Bromfenac (0.032-1.0%; 50 μL) is 26 times more potent than indomethacin in blocking the erythema when applied directly onto the skin area exposed to UV light in guinea pigs[3].
Bromfenac (0.0032-0.1%; 50 μL; rubbed onto the uninjected paw for 4 h per day and 5 days per week) produces a dose and time dependent reduction in the paw volume of both hind limbs in rats[3].
Bromfenac (0.32%; 50 μL; rubbed onto the abdomen) produces significant blockade of abdominal constriction to ACh challenge in mice[3].
Bromfenac (eyedrop instillation; 1 μL (0.09%) per eye; twice-daily; 4 w) partially reduces corneal staining, and becomes so more slowly by the 4-week time point[4].

-
Animal Model:Male Sprague-Dawley rats (150-250 g) are injected carrageenan[3]
-
Dosage:0.0032, 0.01, 0.032, 0.1, 0.32, 1.0, 3.16% (100 or 200 μL)
-
Administration:Rubbed onto the backs before 1-72 h of injected carrageenan
-
Result: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 challenge at 0.2%.
-
Animal Model:Male injected with Salin or BTX-B[4]
-
Dosage:1 μL (0.09%) per eye
-
Administration:Eyedrop instillation; 1 μL (0.09%) per eye; twice-daily; 4 weeks
-
Result:Improved the corneal fluorescein staining score later at 4 weeks after treatment.
