total of eighteen 2-((2-(4-(1H-1,2,4-triazol-1-yl)phenyl)quinazolin-4-yl)oxy)-N-phenylacetamide derivatives were designed and synthesized, via hybrid pharmacophore approach. Among these compounds, chemical structure of compound 4a was unambiguously confirmed by means of single-crystal X-ray diffraction analysis. All the compounds were evaluated in vitro for their inhibition activity against several important
摘要总共设计并合成了18种2-((2-(4-(1 H -1,2,4-三唑-1-基)苯基)喹唑啉-4-基)氧基)-N-苯基乙酰胺衍生物杂交药效团方法。在这些化合物中,通过单晶X射线衍射分析明确地确认了化合物4a的化学结构。体外评估了所有化合物对农业中几种重要植物致病菌和真菌的抑制活性。获得的结果表明,几种化合物显示出对米黄单胞菌PV的有效抗菌活性。稻(Xoo)。例如,化合物4c,4g和4q对这种细菌的EC 50值分别为35.0、36.5和32.4 µg / mL,活性是商业杀菌剂比美噻唑(EC 50 = 89.8 µg / mL)的1.5倍左右。此外,化合物4J和4P被发现显示出针对可比的抗真菌活性的Gloeosporium苹果炭疽病在50微克/毫升,于商业杀菌剂恶霉灵。最后,详细讨论了这类化合物的抗菌活性与分子结构之间的关系。 图形概要
