Bendavia (or SS-31) is a small mitochondrially-targeted tetrapeptide (D-Arg-dimethylTyr-Lys-Phe-NH2) that scavenges mitochondrial reactive oxygen species, inhibits the mitochondrial permeability transition (MPT) pore,[1] and stabilizes cardiolipin.[2]

For elderly mice, it also reduces age-related declines in mitochondrial ATP production, coupling of oxidative phosphorylation (P/O), and cell energy state (PCr/ATP). It also is associated with more reduced glutathione redox status and lower mitochondrial H2O2 emission.[3] It does not have the same effect in younger mice, however.

It was discovered by Cornell professor Hazel Szeto, who later started Stealth Peptides to develop the drug.[4]
