Description
- A four-residue peptide (D-Arg – dimethyltyrosine – Lys – Phe-amide), also known as elamipretide or MTP-131.
- It alternates positively charged and aromatic residues — hence the “aromatic-cationic” label.
- Unlike most peptides in this catalogue it does not act through a receptor on the cell surface; the described target is the inner mitochondrial membrane.
- Supplied as a lyophilised powder for reconstitution.
- Published work describes binding to cardiolipin, a phospholipid found in the cell almost exclusively in the inner mitochondrial membrane.
- Cardiolipin holds the enzyme complexes of the respiratory chain together; the literature examines how binding of the peptide affects it.
- Electron transfer efficiency and the formation of reactive oxygen species are followed.
- The peptide is neither an enzyme nor an inhibitor of one — the described effect is structural.
- Mitochondrial bioenergetics and the respiratory chain.
- Models of mitochondrial myopathy.
- Oxidative stress and its markers.
- Composition and stability of inner-membrane phospholipids.
SS-31 has gone through clinical trials in several indications; a phase 3 study in primary mitochondrial myopathy missed its primary endpoint, and approval has not followed so far. The preclinical literature is extensive and is tied to the conditions it comes from.
