DermorphinGLP-1 / Weight Loss Agonists
Dulaglutide- Summary
- 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.
- Dulaglutide (brand name Trulicity) is a once-weekly GLP-1 receptor agonist approved by the FDA for type 2 diabetes management and cardiovascular risk reduction. It consists of two GLP-1 analog chains fused to a modified IgG4 Fc fragment, extending its half-life to approximately 5 days. While primarily a diabetes medication, it produces meaningful weight loss and has established cardiovascular outcomes data from the REWIND trial.
- Half-Life
- Estimated 30-60 minutes (longer than endorphins due to D-Ala)
- ~5 days
- Admin Route
- Subcutaneous (research), Intrathecal (research), Intranasal (research)
