SS-31

SS-31, also known as Elamipretide, is a mitochondria-targeting tetrapeptide (D-Arg-dimethylTyr-Lys-Phe-NH2) designed to localize selectively to the inner mitochondrial membrane via its affinity for cardiolipin, a phospholipid critical for mitochondrial structural integrity and function. In research settings, SS-31 stabilizes cardiolipin-protein complexes, mitigating oxidative damage and preserving electron transport chain efficiency. This peptide has demonstrated significant potential in reducing reactive oxygen species (ROS) production, enhancing ATP generation, and attenuating mitochondrial permeability transition pore (mPTP) opening in test subjects.

Studies reveal its utility in exploring mitochondrial dynamics, cellular bioenergetics, and the mechanistic pathways of oxidative phosphorylation under conditions of metabolic or oxidative stress. SS-31’s unique biophysical properties enable it to modulate mitochondrial function without altering redox homeostasis, offering a robust platform for investigating mitochondrial resilience and pathophysiology in laboratory research environments.
