What is Dermorphin?
Dermorphin (Tyr-D-Ala-Phe-Gly-Tyr-Pro-Ser-NH₂) is a naturally occurring heptapeptide originally isolated from the skin secretions of South American tree frogs (Phyllomedusa sauvagei). It is one of the most potent and selective μ-opioid receptor (MOR) agonists known, exhibiting approximately 40-fold greater affinity than morphine. For published research, see PubMed studies on Dermorphin{:target=“_blank” rel=“noopener”}.
Notably, Dermorphin contains a D-alanine residue at position 2—an extremely rare occurrence in naturally derived peptides—which confers exceptional resistance to enzymatic degradation and is critical for its potent receptor binding.
Best-Peptides supplies research-grade Dermorphin with guaranteed ≥99% purity and full analytical documentation.
How Does Dermorphin Work?
μ-Opioid Receptor Binding
- High-affinity MOR agonism - Ki in the subnanomolar range
- μ-selectivity - Strong preference over δ- and κ-opioid receptors
- Gi/Go protein coupling - Inhibitory G-protein activation
- Receptor internalisation - Agonist-induced endocytosis
Intracellular Signalling Cascades
- Adenylyl cyclase inhibition - Decreased cAMP production
- K⁺ channel opening - Membrane hyperpolarisation
- Ca²⁺ channel closure - Reduced calcium influx
- MAPK activation - ERK1/2 phosphorylation cascade
Structural Determinants
- D-Ala² residue - Confers metabolic stability and potency
- Tyr¹ and Tyr⁵ - Critical for receptor binding pharmacophore
- C-terminal amidation - Enhanced receptor interaction
- Conformational rigidity - Optimal receptor complementarity

FAQ
Dermorphin is studied as a highly potent and selective μ-opioid receptor (MOR) agonist. Research focuses on opioid receptor pharmacology, pain signalling pathways, receptor binding kinetics, and structure-activity relationships of opioid peptides.
Dermorphin contains a D-alanine residue at position 2, which is extremely rare in vertebrate peptides but common in amphibian skin secretions. This D-amino acid confers exceptional metabolic stability and approximately 40-fold greater μ-receptor affinity than morphine.
Dermorphin binds with high affinity and selectivity to μ-opioid receptors (MOR), activating Gi/Go proteins. This inhibits adenylyl cyclase, opens K⁺ channels, closes Ca²⁺ channels, and activates downstream MAPK signalling cascades.
Store lyophilised Dermorphin at -20°C for long-term stability. Once reconstituted, keep at 2-8°C and use within 4 weeks. Avoid repeated freeze-thaw cycles.
Our Dermorphin is ≥99% pure as verified by HPLC. Each batch includes a Certificate of Analysis with purity data and mass spectrometry identity confirmation.
Yes, Dermorphin is frequently compared with enkephalins, endorphins, and synthetic opioids in receptor selectivity studies. It serves as a reference μ-selective agonist in competitive binding assays.
Reconstitute in sterile bacteriostatic water. Add solvent slowly along the vial wall and gently swirl to dissolve. Dermorphin dissolves readily in aqueous solution.
Dermorphin is available in 2 mg vials, supplied as a pack of 10 × 2 mg for research applications.
