Elamipretide (also known as SS-31, d-Arg-Dmt-Lys-Phe-NH2) is a newly developed antioxidant that specifically targets mitochondria. This peptide, synthesized by Hazel H. Szeto and Peter W. Schiller, contains a dimethyltyrosine residue, enabling it to effectively neutralize harmful oxygen radicals and prevent the oxidation of linoleic acid and low-density lipoproteins.
