Chronic pain in the rat: selective alterations in CNS and pituitary pools of dynorphin as compared to vasopressin.

abstract：:A series of biologically active peptides and related compounds (opioid peptides, neurotensin, and bradykinin) were used as substrates or competitive inhibitors to study the structural requirements for peptide interaction with endopeptidase 22.19. The kinetics of hydrolysis of these peptides indicated that, in contrast...
