Nepafenac (Standard)

Nepafenac (AHR 9434; AL 6515) (Standard) is the analytical standard of Nepafenac (HY-17357). This product is intended for research and analytical applications. Nepafenac, 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 PGE_₂. 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.
