ECHEMI Editorial Reference

Long arginine 3-IGF-1, abbreviated as IGF-1 LR3 or LR3-IGF-1, is a synthetic protein and lengthened analogue of human insulin-like growth factor 1 (IGF-1). It differs from native IGF-1 in that it possesses an arginine instead of a glutamic acid at the third position in its amino acid sequence ("arginine 3"), and also has an additional 13 amino acids at its N-terminus (MFPAMPLLSLFVN) ("long"), for a total of 83 amino acids (relative to the 70 of IGF-1).

Class:
Mitochondria-targeted tetrapeptide (Szeto-Schiller peptide)

Status:
FDA-approved (Forzinity) — Accelerated Approval 2025

Mechanism:
A cell-permeable, synthetic tetrapeptide (D-Arg-Dmt-Lys-Phe-NH₂) that selectively concentrates in the inner mitochondrial membrane and reversibly binds to cardiolipin, a phospholipid essential for electron transport chain (ETC) function. By stabilizing cardiolipin, SS-31 restores mitochondrial bioenergetics, reduces cytochrome c peroxidase activity, and prevents oxidative damage in cells with impaired mitochondrial function.

Activity note:
SS-31 does not act via traditional receptor agonism. It binds cardiolipin with high selectivity in the inner mitochondrial membrane. Functional EC₅₀ values are context-dependent (cell type, stress model). Key electrophysiology studies report mitochondrial membrane potential restoration at nanomolar concentrations.
