SS-31 (Elamipretide) is a mitochondrial-targeted tetrapeptide that selectively binds cardiolipin on the inner mitochondrial membrane. In research models, this interaction has been investigated for its effects on electron transport chain efficiency, reactive oxygen species (ROS) generation, and the stability of cristae architecture.

SS-31 is studied in preclinical models of mitochondrial dysfunction, ischemia-reperfusion injury, age-related muscle wasting, and neurodegeneration, where cardiolipin peroxidation is a central mechanism.
