identified as a racemic, readily available imidazole derivative, significantly less hepatotoxic than tacrine at 100 μM concentration. One compound was found to be a potent antioxidant agent. The catalytic effect of the 1-methylimidazole unit, in the synthesis of some heterocycle, was also demonstrated. Crystal X-ray structures are reported for six compounds. Graphical abstract
摘要制备了带有(苯并)咪唑单元的涉及4 H-吡喃,1,4-二氢吡啶,喹唑啉和2-氨基苯并二氮杂chrome环的新型杂环特权药用支架,并对其产率进行了良好评价,并评估了它们对HepG2细胞和抗氧化剂的体外肝毒性使用DPPH自由基清除法测定其活性。从这些结果来看,2-氨基-4-(1-甲基-1 H-咪唑-2-基)-4 H-苯并[ h] chromene-3-carbonitrile已被确定为外消旋的,易于获得的咪唑衍生物,在100μM浓度下,其肝毒性比他克林低得多。发现一种化合物是有效的抗氧化剂。还证明了1-甲基咪唑单元在某些杂环的合成中的催化作用。报告了六种化合物的晶体X射线结构。 图形概要
