previous fluorinated and/or hydroxylated chalcones studies, thirty-six compounds were designed as phenyl or hydroxyphenyl bearing fluoro, trifluoromethyl or trifluoromethoxy phenyl propenones and synthesized by applying modified Claisen-Schmidt condensation reaction as a single step. Inhibitory effects of the synthesized compounds on ROS production stimulated by LPS in RAW 264.7 macrophage were evaluated
基于先前的氟化和/或羟基化查耳酮研究的重要性,将三十六种化合物设计为带有氟,三氟甲基或三氟甲氧基苯基丙烯酮的苯基或羟基苯基,并通过一步法应用修饰的Claisen-Schmidt缩合反应进行合成。评估了合成的化合物对RAW 264.7巨噬细胞中LPS刺激的ROS产生的抑制作用。结构-活性关系(SAR)研究表明,具有对-羟基苯基与间-氟或间-三氟甲基苯基结合,以及间/对-羟基苯基与邻位结合的化合物-三氟甲氧基苯基在抑制RAW 264.7巨噬细胞中LPS刺激的ROS产生中起重要作用。在具有对-羟基苯基基团和邻-三氟甲氧基苯基基团的化合物30中观察到对RAW 264.7巨噬细胞中LPS刺激的ROS产生的最显着的抑制作用。
