    Chemistry and Biology of the Peptide Anticoagulant D-MePhe-Pro-Arg-H (GYKI-14766)

    The story of D-MePhe-Pro-Arg-H goes back to the mid-70s when its parent compound D-Phe-Pro-Arg-H (GYKI-14166) was discovered1,2.

    Calcium ion uptake, somatotropin release, and fine structure of somatotrophs in cultures of the rat anterior pituitary upon the action of an oligopeptide (Boc-Gln-Leu-Lysinal)

    Cultured cells from the anterior pituitary glands of adult rats were treated with the tripeptide aldehyde proteinase inhibitor, Boc-Gln-Leu-Lys-H. The oligopeptide had a profound relesing effect on growth horm...

    Species differences in the relative analgesic potencies of some classical opiates and opioid peptides

    The analgesic ED50 values of some classical morphine congeners (morphine, methadone, fentanyl, azidomorphine) in the rat and mouse tail-flick tests were found to be similar. However, several synthetic derivatives...

    Effect of met-enkephalin and (d-Met2,Pro5)-enkephalinamide on the adenylate cyclase activity of rat brain

    Among opiatelike peptides, stimulatory as well as inhibitory effects are encountered on adenylate cyclase activity. These actions are dependent not only on the investigated brain region but also on the applied...

    C-terminal fragment (residues 61–91) ofβ-lipotropin: Is it the natural opiate-like neurohormon of the brain?

    The C-terminal fragment of porcine β-lipotropin (residues 61–91) has a very strong analgesic activity in vivo in rats. It is 20 times more potent than morphine if administered intracerebroventricularly (ICV) t...

    Comparative study on analgesic effect of Met5-enkephalin and related lipotropin fragments

    HUGHES et al.1 have reported the isolation and structure of two pentapeptides from porcine brain with opiate agonist activity in isolated systems. The structure of one of these peptides, Met5-enkephalin, is ident...
