Second, the older agents are still approved but rarely chosen for weight management
Neurological Relevance Preclinical evidence suggests broader neuroprotective potential: In traumatic brain injury models, SS-31 reduced mitochondrial swelling, neuronal loss, and neuroinflammation Aged mice treated with SS-31 showed significantly improved exercise tolerance, muscle strength, and mitochondrial efficiency Studies demonstrate protection against ischemic injury and enhanced cardiac output Phase 3 trials are ongoing for dry age-related macular degeneration and primary mitochondrial myopathy (Stealth BioTherapeutics pipeline) Implications for Brain Aging Mitochondrial dysfunction is a hallmark of brain aging and neurodegeneration
PDRN also inhibits microphthalmia-associated transcription factor (MITF), which reduces melanin synthesis
