spinorphin Chemical Properties,Usage,Production
Uses
Spinorphin is a novel neuropeptide, which exhibits complete inhibition of agonist-induced nociception.It is peptide analogs with branched amino acid probes and their therapeutic use.
Definition
ChEBI: Spinorphin is an oligopeptide.
Biological Activity
spinorphin is an endogenous inhibitor of enkephalin-degrading enzymes (aminopeptidase, dipeptidyl aminopeptidase iii, angiotensin-converting enzyme and enkephalinase) [1]. also, it is a potent antagonist of human p2x3 receptor and the n-formylpeptide receptor subtype fpr with ic50 value of 8.3 pm for p2x3 receptor[2][3].enkephalin degrading enzymes are a series of enzymes that hydrolyze enkephalins, which play an important role in management of blood pressure, pain, hypertension and cardiovascular diseases.in human embryonic kidney (hek) 293 cells transfected with mouse fpr, spinorphin induced a typical rise in the intracellular ca2+ concentration with ec50 of 128 μm. also, in normal mouse neutrophils, spinorphin induced calcium flux in a dose-dependent way. while the neutrophils from mice deficient in the fmlf receptor subtype fpr didn’t response [3].in mice, intrathecal administration of spinorphin inhibited the allodynia induced by intrathecal nociceptin in a dose-dependent way. furthermore, spinorphin enhanced the inhibitory effect of enkephalin on allodynia induced by nociceptin [4].
