In this study, series of ring-substituted 2-styrylquinazolin-4(3H)-one and 4-chloro-2-styrylquinazoline derivatives were prepared. The syntheses of the discussed compounds are presented. The compounds were analyzed by RP-HPLC to determine lipophilicity. They were tested for their inhibitory activity on photosynthetic electron transport (PET) in spinach (Spinacia oleracea L.) chloroplasts. Primary in vitro screening of the synthesized compounds was also performed against four mycobacterial strains and against eight fungal strains. Several compounds showed biological activity comparable with or higher than that of the standard isoniazid. It was found that the electronic properties of the R substituent, and not the total lipophilicity of the compound, were decisive for the photosynthesis-inhibiting activity of tested compounds.
本研究制备了一系列环取代的 2-苯乙烯基喹唑啉-4(3H)-酮和 4-氯-2-苯乙烯基喹唑啉衍生物。文中介绍了所讨论化合物的合成方法。化合物通过 RP-HPLC 进行分析,以确定其亲油性。测试了这些化合物对菠菜叶绿体光合电子传递(PET)的抑制活性。此外,还针对四种分枝杆菌菌株和八种真菌菌株对合成的化合物进行了体外初筛。一些化合物显示出与标准异烟肼相当或更高的生物活性。研究发现,R 取代基的电子特性,而不是化合物的总亲油性,对测试化合物的光合作用抑制活性起着决定性作用。
