- MOTS-c
- Activates AMPK and nuclear gene transcription to increase mitochondrial biogenesis
- Nucleus (mitochondrial-to-nuclear signaling)
- Preclinical (Phase I trials planned for 2026–2027)
- Best for increasing mitochondrial density and metabolic flexibility
- Humanin
- Inhibits Bax-mediated apoptosis, preventing mitochondrial membrane permeabilization
- Mitochondrial outer membrane
- Early Phase II (metabolic syndrome trials completed)
- Best for protecting existing mitochondria during oxidative stress
- SS-31 (Elamipretide)
- Binds cardiolipin to stabilize inner membrane and prevent cristae fragmentation
- Inner mitochondrial membrane
- Phase III completed (FDA review ongoing)
- Best for restoring function in damaged mitochondria
- FOXO4-DRI
- Disrupts FOXO4-p53 interaction to clear senescent cells and reduce inflammatory ATP drain
- Cellular senescence pathways (indirect mitochondrial effect)
- Preclinical (senolytic trials in progress)
- Best for eliminating senescent cell burden in aged tissues
