Quick Facts
What is SS-31?
SS-31 (Elamipretide) is a small tetrapeptide that selectively targets cardiolipin in the inner mitochondrial membrane. It was developed to protect mitochondria from oxidative damage and improve their function. The peptide has been studied in various conditions related to mitochondrial dysfunction, including heart failure, muscular dystrophy, and age-related decline in mitochondrial function.
How Does SS-31 Work?
SS-31 concentrates more than 1000-fold in mitochondria, where it binds to cardiolipin, a phospholipid unique to the inner mitochondrial membrane. This binding stabilizes the electron transport chain, prevents cytochrome c release, reduces reactive oxygen species production, and optimizes ATP production. By protecting mitochondrial function, SS-31 may address a fundamental aspect of cellular aging.
