  Synthesis and Biological Evaluation of a Cyclo--tetrapeptide as a Somatostatin Analogue

  摘要：

  Short β-peptides can mimic natural peptide hormones, as has been shown with a cyclo-β-tetrapeptide (1) that displays micromolar affinity to human somatostatin receptors. β-Peptides are thus a promising new class of peptidomimetics with potential high bioavailability due to their excellent resistance against proteases.

  Endomorphin-1 Analogues Containing β-Proline Are μ-Opioid Receptor Agonists and Display Enhanced Enzymatic Hydrolysis Resistance

  摘要：

  In this paper we describe the synthesis and affinity toward the mu-opioid receptor of some tetrapeptides obtained from endomorphin-1, H-Tyr-Pro-Trp-Phe-NH2 (1), by substituting each amino acid in turn with its homologue. The ability to bind p-opioid receptors depends on the beta-amino acid, and in particular 4, which contains beta-L-Pro, has a K-1 in the nanomolar range. The peptides 4 and 5 are significantly more resistant to enzymatic hydrolysis than 1. The same compounds, as well as they-opioid receptor agonist DAMGO, produced a concentration-dependent inhibition of forskolin-stimulated cyclic AMP formation, thus behaving as mu-opioid agonists. These features suggest that this novel class of endomorphin-1 analogues may represent suitable candidates for the in vivo investigation as potential mu-opioid receptor agonists.
