    ‘Click chemistry’ synthesis of a library of 1,2,3-triazole-substituted galactose derivatives and their evaluation against Trypanosoma cruzi and its cell surface trans-sialidase
    摘要:
    Trypanosoma cruzi trans-sialidase (TcTS) plays a key role in the recognition and invasion of host cells and in enabling the parasite to escape the human immune response. To explore this potential drug target, we have synthesized a small library of substrate analogues based on 1,4-disubstituted 1,2,3-triazole derivatives of galactose modified at either the C-1 or C-6 positions. This was achieved by coupling the appropriate azido-sugars with a panel of 23 structurally diverse terminal alkynes by using the copper(I)-catalyzed alkyne-azide cycloaddition (CuAAC) reaction, giving a library of 46 derivatives in good to excellent yield and with complete regioselectivity. The sugar triazoles showed weak inhibition towards TcTS-catalyzed hydrolysis of 2'-(4-methylumbelliferyl)-alpha-D-N-acetylneuraminic acid in vitro (<40% inhibition at 1 mM concentration); many of the compounds assessed proved to be acceptor substrates for the enzyme. Despite this modest inhibitory activity, in vitro trypanocidal activity assays against the trypomastigote form of T. cruzi Y strain revealed several compounds active in the low 100s of mu M range. Further assessment of these compounds against cultured mouse spleen cells suggests a specific mode of anti-parasite action rather than a generic cytotoxic effect. (C) 2010 Elsevier Ltd.

    A general, high-yielding and efficient methodology for the copper catalyzed azide–alkyne cycloaddition (CuAAC) reaction catalyzed by in situ generated copper nanoparticles (CuNPs) or their clusters is reported. This simple reaction is facile in water, organic solvents and solvent-free conditions under ambient, open-air conditions and requires no special reaction conditions and chromatographic separation

The ability to solubilize the copper‐tren complexes in water through the formation of inclusion complexes with β‐CDs is demonstrated. Data is also provided on the fate of the copper(I)‐tren catalytic species when reacting with O2, O2 being used to switch off the catalysis. These data show that partial oxidation of the secondary

    In this article we report the first example of a heterogeneous photolatent catalyst for the copper‐catalyzed azidealkyne cycloaddition (CuAAC) that is supported on chitosan. The heterogeneous copper(II) precatalyst was easily prepared by reaction of [CuII2(3‐benzoylbenzoate)4(H2O)2] complex 1 with chitosan powder. UV‐vis and EPR spectroscopy studies demonstrated that the Cu(II) ions are effectively
    在本文中,我们报告了壳聚糖负载的催化的叠氮化物-炔烃环加成反应(CuAAC)的非均相光潜催化剂的第一个示例。通过使[Cu II 2(3-苯甲酰基苯甲酸酯)4(H 2 O)2 ]配合物1与壳聚糖粉末反应,可以轻松制备多相(II)预催化剂。UV-vis和EPR光谱研究表明,低强度UVA可有效地将Cu(II)离子光还原。特别地,已表明二苯甲酮光敏剂可以催化量使用,即1。e。相对于Cu 2+为10摩尔%离子,以有效地促进Cu(II)到Cu(I)的光还原过程。可以在光照和无抗坏血酸的条件下有效地合成一系列三唑,尤其是那些带有糖部分的三唑。ICP分析没有显示出最终产品中的污染,从而证明了壳聚糖粉末上的紧密结合。由于其非均相性质,催化剂可以被回收并重复使用几次,而催化活性没有明显降低。该方法的实际应用是在10 mmol规模的合成中以82%的收率分离出抗惊厥药rufinamide。
