EUK 134 shows potent catalase and SOD activities, and protects human fibroblasts against cytotoxicity by glucose and glucose oxidase. EUK 134 (20 μM) prevents Aβ-induced microglial proliferation in vitro. In SK-N-MC cells, EUK134 protects neuronal cells against H(2)O(2) toxicity by attenuating oxidative stress through inhibition of MAPK pathway, and also results in decreased expression of pro-apoptotic genes p53 and Bax as well as enhanced expression of anti-apoptotic Bcl-2 gene. EUK 134 significantly inhibits amyloid formation at two molar ratios of 1:1 and 5:1 (drugs to protein).

EUK 134 (2.5 mg/kg), in a middle cerebral artery occlusion model, significantly reduces brain infarct size, and apparently prevents further infarct growth. EUK-134 prevents oxidative stress and attenuates rat brain damage induced by systemic administration of systemic kainic acid (KA).
