ネパフェナク
Based on 1 Customer Validation
Nepafenac (AHR 9434; AL 6515), a nonsteroidal anti-inflammatory agent, is a topically administered COX-2 inhibitor with an IC50 of 0.12 μM. Nepafenac exhibits only weak COX-1 inhibitory activity (IC50 = 64.3 μM). Nepafenac possesses unique prodrug properties, which enable it to rapidly convert into the active metabolite Amfenac (HY-17479) in the ocular tissues, thereby achieving high concentrations in the retina and choroid. Nepafenac reduces inflammation and pain by inhibiting the activity of cyclooxygenase (COX) enzymes and thereby decreasing the production of prostaglandin PGE₂. Nepafenac can delay the metastasis of uveal melanoma (UM) in rabbit eyes. Nepafenac is mainly used for pain management and inflammation control after ophthalmic surgeries.

COX-1 64.3 μM (IC50) |
COX-2 0.12 μM (IC50) |
Nepafenac (0.05%-0.1% eye drops, 0-500 min) inhibits PGE₂ by 90-95% in the isolated rabbit iris/ciliary body and by 55% in the retina/choroid, for a duration of 6 hours and 4 hours, respectively at 1%[1].
Nepafenac (7-117 μM, 0-400 min) has a stronger isolated rabbit corneal and conjunctiva/sclera permeability than Diclofenac (HY-15036) with permeation coefficients (kps) of 727 × 10-6 min-1 and 128 × 10-6 min-1, respectively[2].
Nepafenac (0.05%-0.1% eye drops, 5 min) results in sustained flux of drug across the cornea for 6 h with short term perfusion of the isolated rabbit corneal surface and accumulates at 16.7 μM on the corneal endothelial side[2].
Nepafenac (8.9-140 μM, 0-6 h) can effectively hydrolyze into Amfenac in the cornea, iris/ciliary body, and retina/choroid of both rabbit and human eyes, moreover, the hydrolysis in rabbit cornea shows time and dose dependence[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Nepafenac (0.3% eye drops, topical ocular administration, twice daily for 12 weeks) delays the progression of uveal melanoma (UM) in rabbits[3].

-
Animal Model:Trauma-induced model of acute ocular inflammation established in New Zealand Albino rabbits (2-2.5 kg)[1]
-
Dosage:0.1% eye drops
-
Administration:Topical ocular administration, single dose
-
Result:Reduced protein exudation by 61% and inhibited PGE₂ by 98%. Exhibited the anti-inflammatory effect lasts for 8 hours after a single administration.
-
Animal Model:Human UM cell line induced xenograft tumor model established in male New Zealand albino rabbits[3]
-
Dosage:0.3% eye drops
-
Administration:Topical ocular administration, twice daily for 12 weeks
-
Result:Reduced the incidence of tumors.
Alleviated the tumor morphology, mainly presenting as flat lesions (in the control group, large tumors accompanied by vitreous hemorrhage were more common).
Significantly reduced the staining intensity of COX-2 in tumors. Delayed the appearance time of circulating tumor cells (CMCs), and reduced the lung and liver metastasis of the tumor.
