  具有 4-乙基烷基/芳基硫醚取代基的 1,2,4-三唑-3-硫酮化合物是具有再敏化活性的广谱金属-β-内酰胺酶抑制剂

  摘要：

  金属-β-内酰胺酶（MBLs）是革兰氏阴性菌对β-内酰胺类抗生素耐药的重要因素。MBLs 非常令人担忧，因为它们具有碳青霉烯酶活性，它们在主要的人类机会性病原体中迅速传播，而目前还没有临床上有用的抑制剂。在此背景下，我们正在探索基于 1,2,4-triazole-3-thione 支架的化合物作为 MBL 的二锌活性位点的原始配体的潜力，并在其位置 4 和 5 处进行多种取代。在这里，我们提出了一系列在 4 位被含硫醚的烷基链取代的新化合物，该烷基链在其末端具有羧基和/或芳基。几种化合物对K i显示出广谱抑制作用针对 VIM 型酶、NDM-1 和 IMP-1 的 μM 到亚 μM 范围内的值。硫和芳基的存在对于抑制活性很重要，并且通过 X 射线晶体学揭示了 VIM-2 中一些化合物的结合模式。重要的是，体外抗菌药敏试验表明，几种抑制剂能够增强美罗培南对产生 VIM-1 或 VIM-4 的肺

  Acrylamide-Based Copolymers Bearing Photoreleasable Thiols for Subsequent Thiol–Ene Functionalization

  摘要：

  A new set of monomers is presented in order to incorporate thiols into radical polymers using a protecting chemistry/photocleavage route. The (co)polymerization kinetics of an o-nitrobenzyl thioether-containing acrylamide derivative are reported. The presence of the o-nitrobenzyl moiety is found to strongly affect the polymerization. Nevertheless, water-soluble copolymers with N,N-dimethylacrylamide (DMAAm) as a comonomer are obtained either by free radical polymerization (10 000 <= M-n <= 17 500 g mol(-1); 1.5 <= PDI <= 1.8) or by reversible addition-fragmentation transfer (RAFT)-mediated controlled/living radical polymerization (2000 <= M-n <= 5700 g mol(-1); 1.1 <= PDI <= 1.2). Deprotection under UV light (lambda = 366 nm) at ambient temperature is followed by UV/vis monitoring of the protecting group release, which proceeds to completion between 40 min and 2 h within the studied range of concentration as demonstrated by H-1 NMR spectroscopy. Thiol-maleimide addition is subsequently carried out and found to proceed with a nearly quantitative yield (ca. 90%) as measured by H-1 NMR. Different block copolymers (9400 <= M-n <= 16 500 g mol(-1); 1.3 <= PDI <= 1.4) with a PDMAAm water-soluble block, a polystyrene hydrophobic block, or a poly(N-isopropylacrylamide) thermosensitive block as the first segment and possessing the photoreleasable thiol moieties in the second block are subsequently synthesized by RAFT-mediated polymerization. We finally demonstrate the orthogonal sequential deprotection and reaction with benzyl maleimide of two different thiol species originating from the thiocarbonylthio functionality and the o-nitrobenzyl protected lateral groups, respectively.

  In this study, we reported the synthesis and biological characterization of a novel series of furan-carboxamide derivatives that were potent inhibitors of the influenza A H5N1 virus. The systematic structure–activity relationship (SAR) studies demonstrated that the 2,5-dimethyl-substituted heterocyclic moiety (furan or thiophene) had significant influence on the anti-influenza activity. In particular

  在这项研究中，我们报道了一系列新型的呋喃甲酰胺衍生物的合成和生物学特性，这些衍生物是甲型H5N1流感病毒的有效抑制剂。系统的结构-活性关系（SAR）研究表明，2,5-二甲基取代的杂环部分（呋喃或噻吩）对抗流感活性具有重要影响。特别地，2，5-二甲基-N-（2-（（（4-硝基苄基）硫代）乙基）-呋喃-3-羧酰胺1a显示出对H5N1病毒的最佳活性，其EC 50值为1.25μM。首次将简单的支架呋喃-羧酰胺衍生物鉴定为致命的H5N1甲型流感病毒的新型抑制剂。
• A new strategy for the synthesis of β-benzylmercaptoethylamine derivatives

  Here, we describe a new experimental approach to the synthesis of the beta-benzylmercaptoethylamine functionality, and illustrate its synthetic utility in multi-component reactions. Although prevalent in modern organic synthesis, no general methods have been described for this functionality. Using a carefully developed LiOH-water-ethanol reaction mixture, we were able to produce a diverse collection of beta-benzylmercaptoethylamines containing a range of sensitive functional groups in excellent yields. To further illustrate their utility in molecular library synthesis, we also report the use of beta-benzylmercaptoethylamines in five different multi-component reactions. (C) 2009 Elsevier Ltd.
