Compositions comprising an antioxidant directed or indirectly conjugated to an aromatic-cationic peptide are provide. Said antioxidants are selected from TEMPO, Tro, PBN, AHDP, DBHP, Caf and Hem and may be conjugated to the aromatic-cationic peptide directly or indirectly via a linker to the N-terminus, C-terminus or a side chain of an amino acid residue of the aromatic-cationic peptide. In some embodiments, the aromatic-cationic peptide is 2',6'-Dmt-D-Arg-Phe-Lys-NH2, Phe-D-Arg-Phe-Lys-NH2 or D-Arg-2',6'-Dmt-Lys-Phe-NH2. These conjugates have increased antioxidant activity as compared to the unconjugated aromatic-cationic peptide and have utility in treating complex regional pain syndrome.
提供了包含直接或间接与芳香-阳离子肽结合的抗氧化剂的组合物。所述抗氧化剂从TEMPO、Tro、PBN、AHDP、DBHP、Caf和Hem中选择,并且可以通过连接剂直接或间接地与芳香-阳离子肽结合到N-末端、C-末端或芳香-阳离子肽的氨基酸残基的侧链。在某些实施例中,芳香-阳离子肽为2',6'-Dmt-D-Arg-Phe-Lys-NH2、Phe-D-Arg-Phe-Lys-NH2或D-Arg-2',6'-Dmt-Lys-Phe-NH2。与未结合的芳香-阳离子肽相比,这些共轭物具有增强的抗氧化活性,并可用于治疗复杂性区域性疼痛综合征。
