  Design, Synthesis, and Optimization of Balanced Dual NK₁/NK₃Receptor Antagonists

  摘要：

  In connection with a program directed at potent and balanced dual NK1/NK3 receptor ligands, a focused exploration of an original class of peptidomimetic derivatives was performed. The rational design and molecular hybridization of a novel phenylalanine core series was achieved to maximize the in vitro affinity and antagonism at both human NK1 and NK3 receptors. This study led to the identification of a new potent dual NK1/NK3 antagonist with pK(i) values of 8.6 and 8.1, respectively.

• Synthesis and biological evaluation of analogues of the marine cyclic depsipeptide obyanamide

  to the results, the β‐amino acid residue was found to play a critical role in the biological activities. Additionally, the ester bond along with the Ala(Thz) moiety was also essential for biological activities. However, it seems too early to draw a conclusion that the N‐methylation of Val/Phe can lead to higher or lower cytotoxic activities. Copyright © 2011 European Peptide Society and John Wiley

  在奥巴酰胺的总合成的基础上，通过以下方法合成了该海洋环状双缩肽的20个类似物：（i）使用Z / OtBu方案在西半球中制备三肽片段；（ii）使用Boc / OMe方案在东半球制备二肽片段；（iii）在最后一步中偶联片段，除去保护基团（Boc和OtBu，在一个锅中），以及大环化。细胞毒性测试表明，三种合成化合物对HL-60，KB，LOVO和A549细胞系表现出中等活性。根据结果​​，发现β-氨基酸残基在生物活性中起关键作用。此外，酯键以及Ala（Thz）部分对于生物活性也是必不可少的。但是，现在得出结论认为Val / Phe的N-甲基化可导致更高或更低的细胞毒活性。版权所有©2011欧洲肽协会和John Wiley＆Sons，Ltd.。
• New kelatorphan-related inhibitors of enkephalin metabolism: improved antinociceptive properties

  In order to improve the in vivo protection of enkephalins from enzymatic degradation, a new series of inhibitors derived from kelatorphan [HONHCOCH2CH(CH2Ph)CONHCH(CH3)COOH], the first-described complete inhibitor of enkephalin metabolism, were designed by modification of the C-terminal amino acid. The progressive lengthening of the chain of this residue shows that a beta-alanine seems to be the best basic model for the conception of such types of compounds. On the other hand, the methylation of the amide bond, which is well accepted by aminopeptidase N (EC 3.4.11.2) and dipeptidylaminopeptidase, induced a significant loss of affinity for neutral endopeptidase -24.11. Starting from these data, compounds containing a variously substituted beta-alanine residue and corresponding to the general formula HONHCOCH2CH(CH2Ph)CONHCH(R1)CH(R2)COOH were synthesized. All these molecules inhibit neutral endopeptidase -24.11 and dipeptidylaminopeptidase in the nanomolar range, and those containing an aromatic chain (compound 7A, R1 = CH2Ph,R2 = H, and compound 8A, R1 = Ph, R2 = H) inhibit the biologically relevant aminopeptidase N, with IC50's around 10(-8) M. Intracerebroventricular injection in mice of these multienzyme inhibitors produced an efficient and naloxone-reversible analgesic response (hot plate test): compounds 7A and 8A were shown to be more potent than kelatorphan in increasing the jump latency time, in agreement with their in vitro properties, and these new compounds were found to increase the forepaw lick latency, a reflex considered as a typical morphine response.
• Synthesis of <i>O</i>-Me Ulongamide B and <i>O</i>-Me Ulongamide C, Natural Modified Cyclodepsipeptides

  Synthesis of O-Me ulongamide B and O-Me ulongamide C, modified natural cyclodepsipeptides, was achieved by a convergent route. The respective dipeptides and tridepsipeptides were coupled, obtaining linear depsipentapeptides, which were then deprotected and cyclized. These compounds were tested against three different types of human carcinoma cells and showed only moderate activity.
