Stobadine is a pyridoindole antioxidant.¹It scavenges hydroxyl, peroxyl, and alkoxyl radicals and quenches singlet oxygen in cell-free assays.Ex vivo, stobadine (2 mg/kg) reduces lipid peroxidation induced by hypoxia and reoxygenation in rat forebrain.²It improves survival in a rat model of carotid artery ligation-induced cerebral ischemia. Stobadine (1 mg/kg, i.v.) increases myocardial blood flow and decreases infarct area in a dog model of myocardial infarction induced by acute occlusion of the left coronary artery.¹Dietary administration of stobadine (0.05% w/w) delays the development of cataracts and reduces eye lens protein oxidation and plasma levels of malondialdehyde (MDA) in a rat model of diabetes induced by streptozotocin .³
