Dihexa (also known as N-hexanoic-Tyr-Ile-(6) aminohexanoic amide) is a synthetic peptide derived from angiotensin IV. It was originally developed by researchers at Washington State University as a potential therapeutic for neurodegenerative conditions. Dihexa has been shown in preclinical studies to cross the blood-brain barrier and promote synaptogenesis (the formation of new neural connections). Because of these properties, it has been studied for potential applications in memory, cognition, and brain injury repair. Dihexa remains experimental and is not FDA-approved for therapeutic use.
How It Is Used in Research Settings
- Studied for enhancing synaptic density and plasticity in brain models.
- Explored in Alzheimer’s disease and dementia research for potential cognitive support.
- Investigated in traumatic brain injury (TBI) and stroke models for neural repair.
- Examined for mood and depression-related research due to its impact on neurotrophic factors.
Proposed Uses (Research Areas)
- Neurodegenerative disease research (Alzheimer’s, Parkinson’s).
- Cognitive enhancement and memory studies.
- Traumatic brain injury and stroke recovery models.
- Mood and psychiatric research.
How It Is Dosed in Research Settings
- Oral: Some research protocols examine oral or sublingual administration, typically in the range of 5–20 mg daily.
- Injectable: Investigated at 2–10 mg subcutaneously daily in preclinical settings.
- Cycle length: Research durations vary, from short-term (2–4 weeks) to longer-term studies in cognitive models.
- Handling: Supplied as lyophilized powder; reconstituted with bacteriostatic water or compounded into capsules for research use.
Important Considerations
- Regulatory status: Dihexa is not FDA-approved; all uses remain experimental.
- Evidence base: Data is limited to preclinical studies (animal and in vitro). Human clinical trials have not yet been published.
- Safety: Long-term safety in humans is unknown. While preclinical studies suggest high potency in the brain, toxicity and cancer risk remain theoretical concerns requiring more research.
