S1547	Febuxostat Febuxostat is a selective xanthine oxidase inhibitor with K_i of 0.6 nM.	Free Radic Biol Med, 2015, 10.1016/j.freeradbiomed.2015.02.016 Br J Pharmacol, 2016, 173(14):2290-302	NOX activity was measured as lucigenin-dependent chemiluminescence of superoxide. Incubation with febuxostat increased superoxide generation in nonactivated macrophages, but did not significantly influence superoxide formation in LPS-activated macrophages. Simultaneous treatment with febuxostat abolished the effect of nitrite during activation with LPS. Data are means±SEM (n=10-12). *, p<0.05. LPS, lipopolysaccharide (10 ng/ml); NO2, sodium nitrite (10 μM); febuxostat, xanthine oxidase inhibitor (30 nM).
