  Antibacterial and antifungal activity of acyclic and macrocyclic uracil derivatives with quaternized nitrogen atoms in spacers

  摘要：

  The reactions of 1,3-bis(alpha,omega-bromoalkyl)-6-methyluracils with 1,3-bis(alpha,omega-ethylaminoalkyl)-6-methyluracils or 1,3-bis(bromopentyl)thymine with butylamine afforded pyrimidinophanes containing one or two uracil units and nitrogen atoms in bridging polymethylene chains. In some cases individual geometric isomers of pyrimidinophanes differing in the mutual arrangement of the carbonyl and methyl groups at different pyrimidine rings were isolated. Quaternization of the bridging nitrogen atom with o-nitrobenzyl bromide, benzyl bromide, n-decyl bromide gave rise to water-soluble pyrimidinophanes which were evaluated for their antibacterial and antifungal activity. The arrangement of the carbonyl groups in macrocycles doesn't affect the activity. Antibacterial and antifungal activity of pyrimidinophanes increases with the increase of polymethylene N-(pyr)-N-chain length and dramatically increases upon the introduction of n-decyl substituent at nitrogen atoms in spacers. Pyrimidi-nophanes with 5 and 6 methylene groups in N(pyr)-N-chain and n-decyl substituent showed significant bacteriostatic, fungistatic, bactericidal, fungicidal activity which comparable with standard antibacterial and antifungal drugs. Acyclic counterpart demonstrated the highest activity against fungi. Toxicity of more effective pyrimidinophanes was determined for mice and Daphnia magna Straus. (c) 2006 Elsevier SAS.

  The ability of simple uracils to afford bis(uracil-5-yl)methanes upon reaction with paraformaldehyde is well documented. This reaction has been used in the preparation of pyrimidinophanes. The extension of the scope of this reaction to the synthesis of multipyrimidinophanes has been reported. Starting with isomeric pyrimidinophane containing 6-methyluracil and 5-methyluracil (thymine) moieties, linearly

  简单的尿嘧啶在与多聚甲醛反应后提供双（尿嘧啶-5-基）甲烷的能力已得到充分证明。该反应已用于制备嘧啶烷。已报道将该反应的范围扩展到多嘧啶烷的合成。以含有 6-甲基尿嘧啶和 5-甲基尿嘧啶（胸腺嘧啶）部分的异构嘧啶并烷为起始，制备了线性排列的多大环。一个完全出乎意料的结果是，含有 6-甲基尿嘧啶部分的异构嘧啶烷与多聚甲醛的反应仅产生环状排列的大环，特别是具有环状拓扑结构的穴状嘧啶和多嘧啶。

  6‐methyluracil derivatives are able to penetrate the blood–brain barrier (BBB), inhibiting brain‐tissue AChE. The most potent AChE inhibitor, 3 d (1,3‐bis[5‐(o‐nitrobenzylethylamino)pentyl]‐6‐methyluracil), was found to improve working memory in scopolamine and transgenic APP/PS1 murine models of Alzheimer's disease, and to significantly decrease the number and area of β‐amyloid peptide plaques in the brain

  设计并合成了在嘧啶环的氮原子上具有ω-（取代的苄基乙基氨基）烷基链的新型6-甲基尿嘧啶衍生物。烷基链中亚甲基的数目与苄环上的吸电子取代基一起变化。这些化合物是胆碱酯酶的混合型可逆抑制剂，其中一些对人乙酰胆碱酯酶（hAChE）表现出显着的选择性，其抑制力在纳摩尔范围内，比人丁酰胆碱酯酶（hBuChE）高出1万倍以上。分子模型研究表明，这些化合物是双功能AChE抑制剂，跨越酶的活性位点峡谷并与其外围阴离子位点（PAS）结合。体内实验表明，6-甲基尿嘧啶衍生物能够穿透血脑屏障（BBB），从而抑制脑组织AChE。最有效的AChE抑制剂，3 d（1,3-双[5-（邻硝基苄基乙基氨基）戊基] -6-甲基尿嘧啶）被发现可以改善东pol碱和阿尔茨海默氏病转基因APP / PS1鼠模型的工作记忆，并显着减少数量和脑中β淀粉样蛋白斑块的面积。

  The aggregation and catalytic activity of supramolecular systems based on new macrocyclic dimeric surfactants (pyrimidinophanes) was studied both in the absence and in the presence of polyethyleneimine (PEI). It was found that the critical micelle concentrations measured by tensiometry were independent of the structure of surfactants. The morphology of aggregates was responsible for various characters

  在不存在聚乙烯亚胺（PEI）的情况下，研究了基于新型大环二聚表面活性剂（嘧啶）的超分子体系的聚集和催化活性。发现通过张力测定法测量的临界胶束浓度与表面活性剂的结构无关。聚集体的形态决定了嘧啶亚砜在膦酸酯的水解中的催化作用的各种特征。疏水性较低的嘧啶二甲醚在不存在PEI和存在PEI的情况下均表现出阳离子表面活性剂加速反应的典型作用。与阳离子胶束不同，半胱氨酸嘧啶并烷表现出反常行为：它对底物的水解速率没有影响，也没有抑制水解。加入镧离子后，二聚表面活性剂的催化活性增加。与基于碱性水解的底物相比，由于基于嘧啶基吡啶类，PEI和镧离子的超分子系统的作用，总体催化作用可使底物的水解速度提高三个数量级。

  Novel derivatives based on 6-methyluracil and condensed uracil, 2,4-quinazoline-2,4-dione, were synthesized with terminal meta- and para-benzoate moieties in polymethylene chains at the N atoms of the pyrimidine ring. In the synthesized compounds, the polymethylene chains were varied from having tris- to hexamethylene chains and quaternary ammonium groups; varying substituents (ester, salt, acid) at
