New nonclassical acridines, quinolines, and quinazolines were prepared starting from cyclic β‐diketones, namely dimedone, through application of Hantzsch addition, Michael addition, and Mannich reactions, respectively. The antimicrobial activity revealed that decahydroacridin‐1,8‐dione 2e bearing a 3‐nitrophenyl group and hexahydroquinoline 4e having a 2,4‐dichlorophenyl moiety were the most active
以环状β-二酮即二甲酮为原料,分别通过Hantzsch加成、Michael加成和Mannich反应制备了新的非经典吖啶、喹啉和喹唑啉。抗菌活性表明,基于使用圆盘扩散,带有 3-硝基苯基的十氢吖啶 - 1,8-二酮 2e 和带有 2,4-二氯苯基部分的六氢喹啉 4e 是对革兰氏阳性菌和革兰氏阴性菌最有效的化合物方法。使用 MTT 细胞活力测定法对十氢吖啶 - 1,8 - 二酮 2a - e 对肝癌细胞 (HepG2) 的细胞毒活性研究表明,带有 4 - 甲基苯基部分 2d 的十氢吖啶 - 1,8 - 二酮表现出更高的细胞毒活性 (IC50 = 4.42 µg/mL) 比其他衍生物。
