Abstract

The invention provides a method for treating one or more complications of diabetes in a mammal. The method comprises administering to a mammal in need thereof an effective amount of an aromatic-cationic peptide having at least one net positive charge; a minimum of four amino acids; a maximum of about twenty amino acids; a relationship between the minimum number of net positive charges (p_m) and the total number of amino acid residues (r) wherein 3 p_m is the largest number that is less than or equal to r+1; and a relationship between the minimum number of aromatic groups (a) and the total number of net positive charges (p_t) wherein 2a is the largest number that is less than or equal to p_t+1, except that when a is 1, p_t may also be 1.

Claims

1. A method for treating diabetic retinopathy in a subject in need thereof comprising administering to the subject an effective amount of an aromatic-cationic peptide having the formula D-Arg-2′

6′

-Dmt-Lys-Phe-NH₂ or Phe-D-Arg-Phe-Lys-NH₂ or a pharmaceutically acceptable salt thereof.

2. The method of claim 1, wherein the peptide has the formula D-Arg-2′

6′

-Dmt-Lys-Phe-NH₂.

3. The method of claim 1, wherein the peptide has the formula Phe-D-Arg-Phe-Lys-NH₂.

4. The method of claim 1, wherein the subject is a human.

5. The method of claim 1, wherein the peptide is administered orally, topically, intranasally, systemically, intravenously, subcutaneously, intramuscularly or transdermally.

6. The method of claim 1, wherein the method reduces macrophage infiltration in the subject.

7. The method of claim 1, wherein the method reduces microvascular endothelial cell dysfunction in the subject.
