The preparation of a set of eight closely related biphenyl-thiourea conjugates with aromatic and aliphatic side chains (3a-3h) using a one-pot three-component strategy is reported. All the novel compounds were characterized by spectroscopic techniques (FTIR, 1H and 13C NMR) and elemental analysis. Moreover, the crystal structure of compounds 3f and 3h have been determined by X-ray diffraction. The
报道了使用一锅三组分策略制备具有芳香族和脂肪族侧链 ( 3a-3h )的一组八种密切相关的联苯硫脲缀合物。所有新化合物均通过光谱技术(FTIR、1 H 和13 C NMR)和元素分析进行表征。此外,化合物3f和3h的晶体结构已通过 X 射线衍射测定。共同的分子骨架可以彼此紧密叠加,1-酰基硫脲基团显示出近乎平面的构象,有利于分子内的 N-H•••O=C 键。进行体外研究以测试新合成的联苯硫脲杂化衍生物的弹性蛋白酶抑制活性。在该系列中,化合物3c (IC 50 = 0.26 ± 0.05 μM) 对弹性蛋白酶的抑制作用最大。证明了芳基取代基在烷基链上具有更高的活性,以及吸电子基团的重要性,如硝基 ( 3b和3c ) 和溴 ( 3d ) 以增强酶抑制活性。化合物3c以竞争方式抑制酶,解离常数K i = 0.84 µM。还在酶活性位点内进行分子对接以研究酶-抑制剂相互作用。对接结果与实验
