  A Mitochondria-Targeted Macrocyclic Mn(II) Superoxide Dismutase Mimetic

  摘要：

  Superoxide (O-2(center dot-)) is the proximal mitochondrial reactive oxygen species underlying pathology and redox signaling. This central role prioritizes development of a mitochondria-targeted reagent selective for controlling O-2(center dot-). We have conjugated a mitochondria-targeting triphenylphosphonium (TPP) cation to a O-2(center dot-)-selective pentaaza macrocyclic Mn(II) superoxide dismutase (SOD) mimetic to make MitoSOD, a mitochondria-targeted SOD mimetic. MitoSOD showed rapid and extensive membrane potential-dependent uptake into mitochondria without loss of Mn and retained SOD activity. Pulse radiolysis measurements confirmed that MitoSOD was a very effective catalytic SOD mimetic. MitoSOD also catalyzes the ascorbate-dependent reduction of O-2(center dot-). The combination of mitochondrial uptake and O-2(center dot-) scavenging by MitoSOD decreased inactivation of the matrix enzyme aconitase caused by O-2(center dot-). MitoSOD is an effective mitochondria-targeted macrocyclic SOD mimetic that selectively protects mitochondria from O-2(center dot-) damage.

  The invention provides mitochondrially targeted antioxidant compounds comprising a lipophilic cation moiety covalently coupled to an antioxidant moiety which is either a superoxide dismutase (SOD) mimetic or a glutathione peroxidase mimetic. These compounds can be used to treat patients who would benefit from the reduction of oxidative stress.

  本发明提供了线粒体定向抗氧化化合物，包括一个脂溶性阳离子基团与一个抗氧化基团共价耦合，该抗氧化基团可以是超氧化物歧化酶（SOD）类似物或谷胱甘肽过氧化物酶（GPx）类似物。这些化合物可用于治疗需要减少氧化应激的患者。
