The present investigation describes the synthesis of a series of novel triazole derivatives from 4,4’-dihydroxybenzophenone along with their elastase inhibitory activity. The 1,2,3-triazoles were obtained via the copper(I)-catalyzed azide-alkyne cycloaddition reaction (CuAAC), also known as click reaction, between bis(4-(prop-2-yn-1-yloxy))benzophenone and several benzyl azides. It was found that five
本研究描述了由4,4'-二羟基二苯甲酮合成一系列新型三唑衍生物及其弹性蛋白酶抑制活性。1,2,3-三唑是通过双(4-(prop-2-yn-1-yloxy))之间的铜(I)催化的叠氮化物-炔烃环加成反应(CuAAC)(也称为点击反应)获得的二苯甲酮和几种苄基叠氮化物。发现五种衍生物表现出显着的抑制作用,呈现最大抑制浓度(IC50)值的一半,范围为16.6至72.1μM。发现活性最高的化合物即双(4-(1-(4-碘苄基)-1H-1,2,3-三唑-4-基)甲氧基)二苯甲酮(IC50 = 16.6±1.9μM)与弹性蛋白酶的抑制常数(Ki)为11.12μM,从而说明了竞争性抑制行为。进一步,
