In vitro	Naproxen is approximately equipotent inhibitor of COX-1 and COX-2 in intact cells with IC50 of 2.2 ug/mL and 1.3 ug/mL, respectively. [1] Naproxen decreases the in vitro LPS-induced PGE2 and TXB2 production in rats and humans with IC50 of 30.7 uM and 79.5 uM for PGE2 inhibition, 72.4 uM and 48.3 uM for TXB2 inhibition, respectively. [2] Naproxen produces concentration-related inhibition of TXB2 production from human platelets and LPS-induced TXB2 production from human mononuclear cells with plC50 values (-log concentration inhibiting TXB2 by 50%) of 5.7 and 6.4, respectively, and exhibits slightly inhibitory selectivity for constitutive and induced COX-2 with IC50 COX-1/IC50 COX-2 of 6.3. [3] Only high concentration of Naproxen can significantly induce apoptosis at 48 hours in HCA-7 colon cancer cells with IC50 of 1.45 mM. [4]
In vivo	Administration of Naproxen reduces the LPS-induced PGE2 and TXB2 production in vivo in rats with IC50 values of 12.8 uM and 5.9 uM, respectively, which represents that Naproxen is a nonselective COX inhibitor with the log IC50 ratio (COX-2/COX-1) of 0.34. [2] Naproxen displays IC50 of 27 uM for analgesia in a rat model with carrageenan-induced arthritis and IC50 of 40 uM for antipyretics in a yeast-induced fever rat model, while exhibits inhibition of PGE2 with IC50 of 13 uM and TXB2 with IC50 of 5 uM. [5]
Incubation Time	24 and 48 hours
Kinase Assay	COX-1 and COX-2 activities in intact cells, For the determination of COX-1 and COX-2 inhibition, bovine aortic endothelial cells (BAEC) are incubated for 30 minutes with Naproxen (0.1 ng/mL to 1 mg/mL), and cultured J774.2 macrophages are treated with endotoxin at 1 ug/mL for 12 hours to induce COX-2 followed by incubated for 30 minutes with Naproxen (0.1 ng/mL to 1 mg/mL), respectively. Arachidonic acid (30 uM) is then added, and the cells are incubated for a further 15 minutes at 37 C. The medium is then removed, and radioimmunoassay is used to measure the formation of 6-keto-PGF1alpha, PGE2, thromboxane B2, or PGF2alpha for the assessment of IC50 for COX-1 and COX-2.
Method	Cells are exposed to Naproxen for 24 and 48 hours, respectively. At the end of incubation, cells are harvested by trypsinization, stained with trypan blue solution (0.04% wt/vol) and counted in a Neubauer haemocytometer chamber for the determination of cell viability.
Solubility (25C)	DMSO 3 mg/mL, Water 76 mg/mL, Ethanol 15 mg/mL
