Ebselen is an organoselenium compound that displays anti-inflammatory and antioxidant properties. Ebselen is shown to modify cysteine residues and inhibit the 5-LO (5-lipoxygenase) and 15-LO enzymes in the absence of glutathione. Ebselen also inhibits protein kinase C, cyclooxygenases Cox-1 and Cox-2, NOS (Nitric oxide synthase), GST (glutathione S-transferase), IDO (Indoleamine-pyrrole 2,3-dioxygenase), NADPH (nicotinamide adenine dinucleotide phosphate oxidase), and NADPH oxidase. The oxidation of low density lipoproteins by free radicals is suppressed by the antioxidant action of Ebselen.
