Discovery and biological evaluation of some (1H-1,2,3-triazol-4-yl)methoxybenzaldehyde derivatives containing an anthraquinone moiety as potent xanthine oxidase inhibitors
A series of (1H-1,2,3-triazol-4-yl)methoxybenzaldehyde derivativescontaining an anthraquinone moiety were synthesized and identified as novel xanthine oxidase inhibitors. Among them, the most promising compounds 1h and 1k were obtained with IC50 values of 0.6 μM and 0.8 μM, respectively, which were more than 10-fold potent compared with allopurinol. The Lineweaver-Burk plot revealed that compound
合成了一系列含有蒽醌部分的(1 H -1,2,3-三唑-4-基)甲氧基苯甲醛衍生物,并将其鉴定为新型黄嘌呤氧化酶抑制剂。其中,获得最有前途的化合物1h和1k的IC 50值分别为0.6μM和0.8μM,与别嘌呤醇相比,具有50倍以上的效力。Lineweaver-Burk图显示化合物1h充当了混合型黄嘌呤氧化酶抑制剂。SAR分析表明,对于抑制效力,苯甲醛部分比蒽醌部分起着更重要的作用。黄嘌呤氧化酶被1h显着抑制的基础 通过分子模型研究合理化。
An Efficient Three-Component Reaction of Sodium Azide, Haloalkane and Alkyne for the Synthesis of 1, 2, 3-Triazoles Catalyzed by the Bifunctional Ionic Liquid Catalyst Choline Chloride-CuCl in Water
1, 2, 3-Triazoles were synthesized using a one-pot procedure via a threecomponent reaction between an organichalide, sodium azide and alkyne in the presence of an ionic liquid choline chloride-CuCl catalyst. The catalyst can increase the rate of the nucleophilic substitution reaction and showed a high catalytic activity for the [3+2] Huisgen cycloaddition in water. This method is applicable for a

condensation/cyclization/aromatization sequence toward triazole‐benzimidazolederivatives is disclosed. This methodology provides a general and rapid synthetic route to some new triazole‐benzimidazole hybrids under mild reaction conditions. In addition, the heterogeneous nanocatalyst can be easily separated from the reaction mixture and used several times without noticeable leaching or loss of its catalytic
