Abstract Three 2-phenylthiazole derivatives were synthesized, characterized and evaluated as urease inhibitors. The structures of the 2-phenylthiazole derivatives were characterized by FT-IR, 1H NMR and 13C NMR spectroscopy. Their crystal structures were also determined by single-crystal X-ray diffraction studies. Hirshfeld surfaces analysis and their associated two dimensional fingerprint plots of
摘要 合成、表征和评价了三种 2-苯基噻唑衍生物作为脲酶抑制剂。2-苯基噻唑衍生物的结构通过FT-IR、1H NMR和13C NMR光谱表征。它们的晶体结构也通过单晶 X 射线衍射研究确定。Hirshfeld 表面分析及其相关的化合物二维指纹图被用作理论方法,通过合成化合物的晶格中的分子间相互作用评估晶体结构形成的驱动力。所制备化合物的X射线单晶衍射和Hirshfeld表面分析研究表明合成化合物分子之间存在NH⋯O氢键和CH⋯O分子间相互作用。采用酚红法测定合成化合物的脲酶抑制活性。在三种化合物中,化合物N-环己基-2-(4-甲氧基苯基)噻唑-4-甲酰胺(5b)表现出最好的脲酶抑制活性,IC50为1.82 μM。对接研究表明,化合物N-环己基-2-(4-甲氧基苯基)噻唑-4-甲酰胺可以与脲酶的催化活性位点相互作用。
