The Introduction of Dermorphin

Dermorphin is from a frog and some amphibian skin heptapeptide amide separation, the performance of prolonged opioid-like activity. Applied science: Biochemistry and Molecular Biology (a subject); amino acids, peptides and proteins (two subjects). Skin enkephalin (dermorphin) is opioid peptides (opioids) one.
Endogenous opioid peptides (Endogenous opioids) is produced by the body with morphine (the active ingredient of opium) similar to the physiological role of some of the peptides, including enkephalin, endorphin, dynorphin, enkephalin and skin new skin enkephalin, etc., its role is quite extensive, with more pain research, but its analgesic action principle is still not well understood which new skin FQ (Deltorphins) in 1989 from a South America tree frog found in the skin has a strong analgesic activity of a class of neuropeptides, which combines selective δ receptor。
dermorphin receptor affinity and antinociceptive properties were tested, and with their parents dermorphin. Dermorphin has been selected as the parent compound because of its biological properties and antinociceptive (analgesic characteristics). Dermorphin that high-affinity μ opioid receptor types and antinociceptive activity after the effective application of the systemic (intraperitoneal, ip., Intravenous injection, the former) or central (resulting from the sheath of bone cement, it.) Application. Systems antinociceptive activity is a result, it is important dermorphin blood-brain barrier permeability. Thus, dermorphin is a good long-term effect of the initial peptide molecule to modify a prototype, as a gamma-glutamyl analogue, its activity center management system or less.
