  Pseudoaxially Disubstituted Cyclo-β3-tetrapeptide Scaffolds

  摘要：

  An N,N-disubstituted cyclo-beta(3)-tetrapeptide, identified as a potential molecular scaffold, has been synthesised on a multigram scale from beta-homophenylalanine by employing a nosylate-based protection strategy. C-2-Symmetric derivatives containing pseudoaxial, combinatorially addressable functionalities have been prepared from the parent cyclopeptide. (C) 2000 Elsevier Science Ltd. All rights reserved.

  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.

• Lipase-Involved Strategy to the Enantiomers of 4-Benzyl-β-Lactam as a Key Intermediate in the Preparation of β-Phenylalanine Derivatives
  作者：Xiang-Guo Li、Liisa T. Kanerva

  DOI：10.1002/adsc.200505253

  日期：2006.1

  A simple chemoenzymatic method for the preparation of the enantiomers of 4-benzyl-β-lactam (4-benzylazetidin-2-one) from allylbenzene has been described. The enantiomers of this key intermediate have been used to produce the corresponding enantiomers of β-phenylalanine and N-Boc-protected β-phenylalanine amide through the simple cleavage of the lactam ring by acid-catalyzed hydrolysis and by ammonolysis
