SS-31

Also known as: Elamipretide

SS-31 (elamipretide) is a mitochondria-targeted tetrapeptide (D-Arg-Dmt-Lys-Phe-NH2) developed by Hazel Szeto (Cornell) and clinically advanced by Stealth BioTherapeutics. It concentrates in the inner mitochondrial membrane by binding cardiolipin. In September 2025, the FDA granted accelerated approval to elamipretide (brand name FORZINITY) as the first therapy for Barth syndrome — the first FDA-approved mitochondria-targeted drug. It remains investigational for other indications.

Elamipretide (SS-31) promotes recovery by preserving mitochondrial bioenergetics and neural remodeling after spinal cord injury

Spinal cord injury (SCI) induces secondary damage characterized by mitochondrial dysfunction, oxidative stress, and apoptosis, which collectively impede neurological recovery. Elamipretide (SS-31) is a mitochondria-targeting peptide with potential neuroprotective effects.

SLC25A28 Ameliorates Hyperoxic Lung Injury by Improving Mitochondrial Oxidative Phosphorylation in Alveolar Epithelial Cells

Mitochondrial dysfunction plays a central role in the pathogenesis of bronchopulmonary dysplasia (BPD). Solute carrier family 25 member 28 (SLC25A28) is an iron transporter located in the inner mitochondrial membrane. In this study, we aimed to explore the role and underlying molecular mechanisms of SLC25A28 in BPD.

Mechanisms of Anti-Oxidants, N-Acetylcysteine and Elamipretide (SS-31), on Ozone-Induced Airway Hyperresponsiveness and Mucus Hypersecretion

Background Ozone (O₃) exposure induces acute airway injury characterized by airway hyperresponsiveness (AHR) and airway mucus hypersecretion (AMH). Oxidative stress and mitochondria-derived reactive oxygen species (mtROS) are key contributors.

Restoring cardiolipin homeostasis mitigates cerebral ischemia-reperfusion injury by suppressing ATG5-mediated neuronal autophagy-dependent ferroptosis

Introduction Cardiolipins (CLs) are mitochondria-specific phospholipids critically involved in neurological disorders. However, their roles in cerebral ischemia/reperfusion (I/R) injury remains largely underexplored.
