Dermorphin- Summary
- ARA-290 is a synthetic 11-amino acid peptide derived from the helix B region of erythropoietin (EPO). Unlike EPO, it selectively activates the innate repair receptor (IRR) without stimulating hematopoiesis, providing tissue protection, anti-inflammation, and neuropathy relief.
- Dermorphin is a naturally occurring heptapeptide opioid isolated from the skin of South American phyllomedusine frogs. It is one of the most potent endogenous mu-opioid receptor agonists known, approximately 30-40 times more potent than morphine by weight. Explored for pain management and fatigue modulation.
- Half-Life
- ~2–4 hours (SC administration)
- Estimated 30-60 minutes (longer than endorphins due to D-Ala)
- Admin Route
- SubQ
- Subcutaneous (research), Intrathecal (research), Intranasal (research)
