What is SS-31?
SS-31 has the particularity of concentrating in the inner membrane of the mitochondria, where it interacts with cardiolipin, a key lipid for energy production. Because of that mechanism it is classified as a mitochondria-targeted peptide.
Research context
The preclinical and clinical literature on SS-31 / elamipretide has focused on mitochondrial bioenergetics and models of mitochondrial dysfunction.
