Product Description

Nepafenac (formerly AHR9434; AL 6515; AL-6515; AHR-9434; Nevanac; Nevanac) is a potent non-steroidal anti-inflammatory drug (NSAID), and a prodrug of amfenac that acts as an inhibitor of COX-1 and COX-2 enzyme activity. It was approved for the treatment of pain and inflammation associated with cataract surgery. Nepafenac showed to significantly decrease the retinal levels of PGE2 in LPS-induced rats when administrated topically. However, nepafenac has revealed no significant effect on BRB permeability in LPS-induced rat model.

Biological Activity I Assay Protocols (From Reference)

ln Vitro

In vitro activity: Nepafenac is a non-steroidal anti-inflammatory drug (NSAID). The IC50 values of nepafenac for (cyclooxygenase-1) COX-1 and COX-2 are 250 nM and 150 nM, respectively.

Cell Assay: Nepafenac significantly reduced proliferation rate of human uveal melanoma cell lines including SP6.5, 92.1, OCM-1, MKT-BR and of human transformed uveal melanocyte cell line UW-1. Compared to rofecoxib, nepafenac might reveal a better systemic safety profile.

ln Vivo

Nepafenac shows significantly greater ocular bioavailability and amfenac demonstrated greater potency at COX-2 inhibition than ketorolac or bromfenac. Nepafenac exhibits only weak COX-1 inhibitory activity with IC50 of 64.3 mM. Nepafenac inhibits prostaglandin synthesis in the iris/ciliary body (85-95%) and the retina/choroid (55%) in rabbits. Nepafenac (0.5%) produces 65% reduction in retinal edema which is correlated with 62% inhibition of blood-retinal barrier breakdown. Nepafenac (0.5%) significantly inhibits (46%) blood-retinal barrier breakdown concomitant with near total suppression of PGE2 synthesis (96%). Nepafenac significantly inhibits retinal prostaglandin E(2), superoxide, cyclooxygenase-2, and leukostasis within retinal microvessels in insulin-deficient diabetic rats, without affecting vascular endothelial growth factor (VEGF) and nitric oxide (NO). Nepafenac significantly inhibits the number of transferase-mediated dUTP nick-end labeling-positive capillary cells, acellular capillaries, and pericyte ghosts in diabetic rats. Nepafenac results in significantly less choroidal neovascularization and significant less ischemia-induced retinal neovascularization in mice compare to control. Nepafenac also blunts the increase in VEGF mRNA in the retina induced by ischemia. Nepafenac delays the progression of malignancy as well as reduces weight in an ocular and metastatic animal model of uveal melanoma.

Solubility Data

Solubility (In Vitro)

DMSO: 50 mg/mL (196.6 mM)

Water:<1 mg/mL

Ethanol:<1 mg/mL

Preparing Stock Solutions		1 mg	5 mg	10 mg
	1 mM	3.9327 mL	19.6634 mL	39.3267 mL
	5 mM	0.7865 mL	3.9327 mL	7.8653 mL
	10 mM	0.3933 mL	1.9663 mL	3.9327 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.

Molarity Calculator allows you to calculate the mass, volume, and/or concentration required for a solution, as detailed below:

Calculate the Mass of a compound required to prepare a solution of known volume and concentration
Calculate the Volume of solution required to dissolve a compound of known mass to a desired concentration
Calculate the Concentration of a solution resulting from a known mass of compound in a specific volume

See Example

An example of molarity calculation using the molarity calculator is shown below:
What is the mass of compound required to make a 10 mM stock solution in 5 ml of DMSO given that the molecular weight of the compound is 350.26 g/mol?

Enter 350.26 in the Molecular Weight (MW) box
Enter 10 in the Concentration box and choose the correct unit (mM)
Enter 5 in the Volume box and choose the correct unit (mL)
Click the “Calculate” button
The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.
