Dermorphin
Overview
Dermorphin is a heptapeptide opioid agonist originally isolated from the skin of South American Phyllomedusa frogs. It exhibits high selectivity and affinity for the mu-opioid receptor, with potency approximately 30 to 40 times greater than morphine in animal models.
Mechanism of Action
The unique D-alanine residue at position 2 confers resistance to peptidase degradation and contributes to its prolonged analgesic activity. Its potent receptor binding has made it a valuable research tool for studying opioid receptor pharmacology.
Research Summary & Key Findings
Preclinical studies in rodents have demonstrated potent antinociceptive effects following intracerebroventricular and systemic administration. Dermorphin has been used extensively in laboratory settings to map mu-opioid receptor distribution and function. No human clinical trials have been conducted, and its use remains confined to experimental neuropharmacology research.
Clinical Status
Dermorphin is in the research phase with limited clinical data in humans. Current evidence is primarily derived from preclinical (animal or in vitro) studies.
