What is Dermorphin (High-Dose)??

Dermorphin (CAS 77614-16-5) is a naturally occurring heptapeptide opioid first isolated from the skin of South American frogs (Phyllomedusa sauvagei). Sequence: H-Tyr-D-Ala-Phe-Gly-Tyr-Pro-Ser-NH₂. Molecular formula C₄₀H₅₀N₈O₁₀, MW 802.88 g/mol. This 10mg/vial high-dose format supports dose-escalation studies, multi-arm MOR pharmacology experiments, and long-duration in vivo analgesic paradigms requiring larger quantities. Dermorphin exhibits approximately 1,000-fold greater µ-opioid receptor (MOR) potency than morphine in preclinical binding assays, with high selectivity for MOR over δ and κ subtypes. The D-Ala² residue confers DPP-IV and protease resistance, extending half-life relative to linear endogenous opioids.

Research Applications

High-Dose MOR Pharmacology

Dose-escalation µ-opioid receptor occupancy, Gi/o signalling kinetics, receptor saturation profiling

Analgesic Dose-Response

Multi-arm hot-plate/tail-flick/formalin models across concentration range — morphine comparison

Tolerance & Sensitisation

Repeated high-dose MOR stimulation, receptor internalisation, GIRK channel desensitisation

β-Arrestin & Biased Agonism

β-arrestin-2 recruitment, ERK1/2 phosphorylation bias vs. G-protein signalling at elevated concentrations

D-Amino Acid Stability

DPP-IV resistance profiling — D-Ala² contribution to plasma and tissue half-life

Frequently Asked Questions

How do I reconstitute this peptide?
Add 1–2mL bacteriostatic water to the lyophilized vial by directing water down the inner wall of the vial. Swirl gently until the powder fully dissolves — do not shake or vortex. The solution should be clear and colourless. Use immediately or refrigerate at 2–8°C.
How should this peptide be stored?
Store lyophilized peptide vials at −20°C for long-term storage. Once reconstituted, store at 2–8°C (refrigerator) and use within 21–28 days. Avoid repeated freeze-thaw cycles, direct light, and heat exposure.
What purity is this QSC compound and how is it verified?
All QSC compounds are tested to ≥99% purity by HPLC peak area analysis on every production batch. Molecular identity is confirmed by mass spectrometry. A Certificate of Analysis (COA) is published on the product page and independently verifiable at verify.janoshik.com using the batch reference number.
