EUK-134 (10-300 μM) is able to improve cell viability and reduces Paraquat (1 mM)-induced cell death significantly via dismutation or scavenging of superoxide anions and reduces hydroxyl radical generation[2]. Higher concentrations of EUK-134 alone (30-300 μM) produces modest but significant reductions in cellular viability; however, this effect is not reflected in cell death measurements made at these concentrations[2]. EUK-134 is a salen-manganese complex with superoxide dismutase and catalase activity.Supplementation with EUK-134 is therefore identified as a novel approach to attenuate cardiac hypertrophy and lends scope for the development of EUK-134 as a therapeutic agent in the management of human cardiovascular disease.EUK-134 is a mitoprotective antioxidant with Mn-superoxide dismutase (Mn SOD) and catalase activity[3]. Cell Viability Assay[2] Cell Line: NRK-52E cells Concentration: 0, 1, 3, 10, 30, 100, and 300 μM Incubation Time: 24 hours Result: Co-incubation with Paraquat (1 mM) and increasing concentrations of EUK-134 (1-300 μM) resulted in a significant reduction in paraquat-induced cellular injury and death at 100 and 300 μM.
