  Facile incorporation of urea pseudopeptides into protease substrate analogue inhibitors

  摘要：

  A new procedure that employs a one-pot, oxidative Hofmann rearrangement to incorporate a urea linkage into peptide backbones is detailed herein. This methodology was used to replace the scissile peptide bonds of [Leu(5)]enkephalin and a hexapeptide HIV-1 protease substrate. The [Leu(5)]enkephalin analogue was found to inhibit cleavage of hippurylhistidylleucine (HHL) by porcine kidney angiotensin-converting enzyme (PK-ACE) with a 0.88 mM IC50 value, comparable to the Michaelis constant of [Leu(5)]enkephalin with the same enzyme. The HIV-1 protease substrate analogue was shown to inhibit HIV-1 protease with an IC50 = 34muM. (C) 2004 Elsevier Ltd. All rights reserved.

  direct precursors of 1,3,5-triazepan-2,6-diones, a novel class of conformationally constrained dipeptide mimetics. Herein, we have evaluated the use of these building blocks for the synthesis of ureido-peptides (in solution and on solid support), peptidyl hydantoins, oligoureas and some oligo(urea/amide) hybrids.

  A simple protocol for the synthesis of N-urethane-protected N-alkyl-Se-alkyl selenocarbamate derivatives of amino acids has been described. The reaction of N-urethane-protected amino alkyl isocyanates with selenating agent LiAlHSeH and subsequent coupling with an alkyl halide yielded the title compounds in good yield and purity. All the selenocarbamates obtained have been characterized by 1H NMR, 13C NMR, and mass spectral studies.
