DELTORPHIN II Chemical Properties,Usage,Production
Uses
[D-Ala2]-Deltorphin II (cas# 122752-16-3) is a useful research chemical.Deltorphin II is one of the naturally occurring peptides with high affinity and selectivity for δ-??opioid binding sites. Deltorphin II showed even higher affinity for δ-??opioid receptors than previously characterized deltorphins. Also, Deltorphin II were identified as new transport substrates of OATP-??A
Definition
ChEBI: Deltorphin B is a peptide.
Biological Activity
[d-ala2]-deltorphin ii (dadelt ii) is a natural agonist of δ opioid receptor with ki or ic50 value of 0.41 nm [1, 2].opioid receptors are most abundant in the central nervous system, but are also localized in many peripheral tissues in mammalian organisms. there are three types of opioid receptors that are well-defined; the μ, δ and κ receptors [2].[d-pen2, d-pen5]enkephalin (dpdpe) is a second highly selective agonist of δ [3]. treatment with dpdpe at 1 m for as short as 3 min significantly diminished the inhibition of the opioid receptor in ng108-15 cells to cyclic amp production. that means neuronal delta opioid receptor underwent acute desensitization. this desensitization was temporally parallel to the phosphorylation of delta opioid receptor 3 min. after agonist stimulation [4].i.c.v. administration of dadelt ii from 0.38-12.78 nm resulted in a dose- and time-related antinociception. 10 min after the administration of dadelt ii, the maximal antinociceptive response was seen. until 60 min after the administration of dadelt ii, effects were detected. these antinociceptive effects of i.c.v. dadelt ii were antagonized by the selective δ antagonist, ici 174,864 [3]. after supraspinal and spinal administration in rats intracerebroventricularly, dadelt ii at 0.2, 1, 10 μg/rat in a dose-related fashion inhibited diarrhea and colonic bead expulsion but did not show any effect on the rate of small intestine transit. spinal administration of dadelt ii at the same dose produced similar results. naltrindole is a selective antagonist of the δ opioid receptor. subcutaneous pretreatment with naltrindole at 1 and 10 mg/kg antagonized effects of dadelt ii partially and completely, respectively [1].
