SS-31 is a synthetic tetrapeptide with the sequence D-Arg-Dmt-Lys-Phe-NH2, where Dmt stands for 2′,6′-dimethyltyrosine. It is manufactured via solid-phase peptide synthesis and supplied as a high-purity lyophilized powder, typically ≥98% by HPLC. The molecule is designed to target the inner mitochondrial membrane and is used in research and pharmaceutical development.
As a mitochondria-targeted peptide, SS-31 has attracted interest for its ability to interact with cardiolipin and stabilize mitochondrial cristae. It is explored in preclinical and clinical settings for conditions involving mitochondrial dysfunction, such as ischemia-reperfusion injury, heart failure, and certain rare diseases. Its well-defined mechanism and favorable safety profile make it a valuable tool for both research and formulation development.
