COA 产品使用指南 技术支持

Nepafenac (AHR 9434; AL 6515),一种非甾体类抗炎剂,是一种局部给药的 COX-2 抑制剂,IC50 为 0.12 μM。Nepafenac 仅表现出较弱的 COX-1 抑制活性 (IC50 = 64.3 μM)。Nepafenac 具有独特的前体药物特性,使其能够在眼组织中快速转化为活性代谢物 Amfenac (HY-17479),从而在视网膜和脉络膜中达到高浓度。Nepafenac 通过抑制环氧合酶 (COX) 的活性,从而减少前列腺素 PGE 的产生,从而减轻炎症和疼痛。Nepafenac 可以延缓兔眼葡萄膜黑色素瘤 (UM) 的转移。Nepafenac 主要用于眼科手术后的疼痛管理和炎症控制。

生物活性

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 PGE. 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[1][2][3].

体外研究
(In Vitro)

Nepafenac (0.05%-0.1% 滴眼液,0-500 分钟) 在浓度为 1% 时可抑制离体兔虹膜/睫状体 (90-95%) 和视网膜/脉络膜 (55%) 中 PGE,持续时间分别为 6 小时和 4 小时[1]
Nepafenac (7-117 μM,0-400 分钟) 对离体兔角膜和结膜/巩膜的渗透性比 Diclofenac (HY-15036) 更强,渗透系数 (kps) 分别为 727 × 10-6 min-1 和 128 × 10-6 min-1[2]
Nepafenac (0.05%-0.1% 滴眼液,5 分钟) 可在兔离体角膜表面短时间内灌注,导致药物持续 6 小时通过角膜,并在角膜内皮侧积累 16.7 μM[2]
Nepafenac (8.9-140 μM,0-6 小时) 可在兔和人眼的角膜、虹膜/睫状体和视网膜/脉络膜中有效水解为 Amfenac,并且其在兔角膜中的水解呈现时间和剂量依赖性[2]

体内研究
(In Vivo)

Nepafenac (0.1% 滴眼液,局部眼部给药,单剂量) 在创伤诱发的兔急性眼部炎症模型中表现出强效且持久的抗炎作用[1]
Nepafenac (0.3% 滴眼液,局部眼部给药,每日两次,持续 12 周) 可延缓兔葡萄膜黑色素瘤 (UM) 的进展[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.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
