We describe the synthesis, physicochemical, and biological properties of a novel series of 7-imidazolyl-6-trifluoromethyl quinoxalinecarboxylic acids with a substituted phenyl group attached through a urethane linkage at the C-7 position. We found that the introduction of trifluoromethyl group at the C-6 position brought about good biological activity and physicochemical properties. Among them, compound
我们描述了一系列新的7-咪唑基-6-三氟甲基喹喔啉羧酸的合成,物理化学和生物学特性,这些取代羧酸具有通过C-7位置的氨基甲酸酯键连接的取代苯基。我们发现在C-6位引入三氟甲基带来了良好的生物活性和理化性质。其中,具有4-羧基苯基的化合物9k(KRP-199)在体外具有对AMPA-R的高效力和选择性,并且在体内具有良好的神经保护作用。此外,该化合物表现出良好的理化性质,例如对光的稳定性和在水溶液中的良好溶解性。
