SS-31

CAS: 736992-21-5

Mitochondrial dysfunction and aging · Barth syndrome (FDA-approved indication) · Heart failure and cardiac ischemia-reperfusion

SS-31 is a cell-permeable, mitochondria-targeted tetrapeptide that concentrates ~1000-fold in the inner mitochondrial membrane by binding to cardiolipin, a phospholipid unique to this membrane.

  • Mitochondrial dysfunction and aging
  • Barth syndrome (FDA-approved indication)
  • Heart failure and cardiac ischemia-reperfusion
  • Acute kidney injury

How SS-31 Works

SS-31 is a cell-permeable, mitochondria-targeted tetrapeptide that concentrates ~1000-fold in the inner mitochondrial membrane by binding to cardiolipin, a phospholipid unique to this membrane. By stabilizing cardiolipin's interaction with cytochrome c, SS-31 optimizes electron transport chain efficiency, reduces electron leak, and decreases mitochondrial reactive oxygen species (ROS) production. It does not act as a traditional antioxidant scavenger but rather prevents ROS formation at the source by maintaining proper mitochondrial function.
