About this compound

SS-31 (Elamipretide / MTP-131 / Bendavia)

CAS Number: 736992-21-5
Molecular Formula: C32H49N9O5
Molecular Weight: ~639.8 g/mol
Sequence: D-Arg-dimethylTyr-Lys-Phe-NH2
Synonyms: Elamipretide, MTP-131, Bendavia, Szeto-Schiller Peptide 31

Description:
SS-31 (Elamipretide) is a mitochondria-targeted tetrapeptide engineered to selectively bind cardiolipin within the inner mitochondrial membrane. This interaction stabilizes mitochondrial structure, enhances ATP synthesis efficiency, and reduces the formation of reactive oxygen species (ROS).

Research suggests that SS-31 supports mitochondrial integrity under oxidative or metabolic stress and has been studied in experimental models of cardiovascular disease, neurodegeneration, renal injury, and age-related mitochondrial dysfunction. Its unique sequence allows for rapid cell penetration and accumulation in mitochondria, making it valuable in studies exploring cellular energy regulation, oxidative balance, and mitochondrial protection.

Form: Lyophilized powder
Amount: 10 mg per vial
Purity: ≥98% (HPLC)
Storage: Store at –20 °C. Protect from light and moisture.
Solubility: Soluble in sterile water, acetic acid, or appropriate buffer.
