Synthetic Antioxidants and Eukarion USC researchers have found that synthetic antioxidant compounds that mimic the activity of superoxide dismutase and catalase, made by the company eukarion (alas, not publicly traded), delay memory loss in mice. It is thought that oxidative stress plays a central role in many facets of aging, and thus unique antioxidant compounds such as these hold much promise for increasing health and longevity. The Buck Institute has found previously that the reduced longevity of transgenic mice lacking superoxide dismutase is reversed when eukarion compounds are adminstered to them. They additionally found that the onset of neuropathologic disorders was attenuated with the administration of the compounds. With wildtype C. elegans, Buck researchers were able to increase lifespan approximately 50%. EurekAlert Article
