SS-31

Mitochondria-targeting tetrapeptide

A mitochondria-targeting tetrapeptide, also known as elamipretide, studied clinically for mitochondrial diseases and other conditions involving mitochondrial dysfunction.

Mechanism under study

SS-31 concentrates in the inner mitochondrial membrane and binds the phospholipid cardiolipin. This is proposed to stabilize cristae structure, support efficient electron transport, and reduce reactive-oxygen-species production.

Research-reported dosing

Investigational (as elamipretide). Clinical trials in mitochondrial disease and related conditions used roughly 40 mg/day subcutaneously. Not approved.

Reconstitution

Based on a standard 10 mg vial: with 2 mL bacteriostatic water = 5,000 mcg/mL (5 mg/mL); 1 unit ≈ 50 mcg.
