Description

Description générale

A cell-permeable, irreversible endothelial nitric oxide synthase inhibitor. Inhibits iNOS in macrophages (IC₅₀ = 5 nM). Shown to inhibit acetylcholine-induced relaxation of preconstricted rat thoracic aortic rings (IC₅₀ = 180 nM). Blocks K⁺ and Ca²⁺ currents in arterial smooth muscle cells. Inhibitor of mitochondrial NADH-ubiquinone oxidoreductase. Inhibits other NADH utilizing flavoproteins, such as NADPH oxidase in human neutrophils and macrophages. Causes pressor and tachycardiac effects via indirect activation of the sympathetic nervous system.

A cell-permeable, irreversible inhibitor of endothelial nitric oxide synthase (eNOS). Shown to inhibit acetylcholine-induced relaxation of preconstricted rat thoracic aortic rings (IC₅₀ = 180 nM). Also inhibits iNOS in macrophages (IC₅₀ = 50 nM). Blocks K⁺ and Ca²⁺ currents in arterial smooth muscle cells. Inhibitor of mitochondrial NADPH-ubiquinone oxido-reductase.
