High impact information on Endomorphin 2

  • We have synthesized and pharmacologically characterized a chimeric peptide containing overlapping NH(2)- and COOH-terminal functional domains of the endogenous opioid endomorphin-2 (EM-2) and the tachykinin SP, respectively [8].
  • We recently reported the use of an exhaustively stereodiversified library based on endomorphin-2 (1) to discover mu opioid receptor (MOR) ligands of type 2-4 [9].
  • After injection of Fluoro-Gold into the medial zone of hypothalamic tuberal region and the lateral hypothalamic area, respectively, endomorphin 1/Fluoro-Gold or endomorphin 2/Fluoro-Gold double-labeled neuronal cell bodies were found chiefly in the medial, commissural, lateral and gelatinous parts of the nucleus tractus solitarii [10].
  • These results suggest that the spinal antinociception induced by endomorphin-2 is mediated through the stimulation of a distinct subtype of mu(1)-opioid receptor that induces the release of the endogenous kappa-opioid peptide dynorphin A-(1-17) in the spinal cord [11].
  • Inhibition by endomorphin-1 and endomorphin-2 of excitatory transmission in adult rat substantia gelatinosa neurons [12].
