  氨基酸衍生重氮酮有机合成耐贮存试剂的实用合成方法

  摘要：

  提出了一种使用串联流动反应器安全生成含重氮甲烷的有机溶液的新方法。重氮甲烷的生成产率达到0.45mol/h。通过重氮甲烷与混合酸酐的反应，已经制备了几种手性重氮酮，其数量高达 150 g，混合酸酐是通过用氯甲酸乙酯处理 Boc 保护的 α-氨基酸原位生成的。合成的重氮酮是在 110-142 °C 下稳定的结晶物质，可以很容易地在硅胶上纯化并长期保存。总体稳定性和大规模可用性允许将此类重氮酮视为具有广泛应用前景的实验室稳定试剂。量子化学研究表明，重氮酮的稳定性与羰基与重氮部分的共轭有关。作为适用性的一个例子，重氮酮与浓 HBr 的反应无需额外纯化即可得到相应的纯手性 α-溴酮。

  improvement in the inhibition of DAP and APN, in the first series of inhibitors, while the inverse result occurred in the second series. Thus, compounds containing an alpha-amino acid moiety in P'1 position behave as weak inhibitors of the three enzymes, with IC50 values in the micromolar range, and compounds bearing a beta-amino acid moiety in the same position are more specific than the parent compounds

  β‐Amino acids containing α,β‐hybrid peptides show great potential as peptidomimetics. In this paper, we describe the synthesis and affinity to μ‐opioid and δ‐opioid receptors of α,β‐hybrids, analogs of the tetrapeptide Tyr‐ d‐Ala‐Phe‐Phe‐NH2 (TAPP). Each amino acid was replaced with an l‐ or d‐β3‐h‐amino acid. All α,β‐hybrids of TAPP analogs were synthesized in solution and tested for affinity to μ‐opioid

  structure and stereochemistry of polyoximic acid, a degradation product of polyoxins, was originally designated as trans-3-ethylidene-L-azetidine-2-carboxylic acid. However, total synthesis revealed that the correct structure was in fact cis-3-ethylidene-L-azetidine-2-carboxylic acid, which was confirmed by X-ray crystallography. The synthesis of the trans-isomer was also done and its identity was confirmed

• Design of novel inhibitors of aminopeptidases. Synthesis of peptide-derived diamino thiols and sulfur replacement analogs of bestatin
  作者：E. M. Gordon、J. D. Godfrey、N. G. Delaney、M. M. Asaad、D. Von Langen、D. W. Cushman

  Investigations were directed toward inhibition of an aminopeptidase, isolated from rat brain, which has been implicated in the metabolic inactivation of enkephalins. The design rationale and synthesis of novel peptidyl diamino thiol inhibitors of rat brain aminopeptidase are presented, along with accompanying structure-activity analysis. Some of the reported compounds are highly active aminopeptidase inhibitors and possess enzyme inhibitory potency in the nanomolar range (62; I50 = 1 nM). Analysis of the data permits speculations on possible modes of binding of diamino thiols to aminopeptidase. Other investigations were directed toward understanding the mode of enzyme binding of the naturally occurring aminopeptidase inhibitor bestatin. On the basis of published models of enzyme binding, replacement of the C-2 hydroxyl group of bestatin by a sulfhydryl group was anticipated to lead to enhanced inhibition due to a strengthened interaction of this group with enzymic zinc. Contrary to expectations, "thiobestatin" inhibited rat brain aminopeptidase with only the same degree of effectiveness as the corresponding alcohol. Speculations on the possible mode of enzyme-inhibitor binding of bestatin are offered.
