This paper describes the discovery of a novel free radical scavenger, 3-methyl-1-phenyl-2-pyrazolin-5-one (edaravone, 1), as a potent antioxidant agent against lipid peroxidation. The structure-activity relationship of edaravone indicated that lipophilic substituents were essential to show its lipid peroxidation-inhibitory activity. In vivo studies revealed that edaravone showed brain-protective activity in a transient ischemia model.
本文描述了一种新型自由基清除剂3-甲基-1-苯基-2-吡唑啉-5-酮（依达拉奉，1）作为一种有效的抗脂质过氧化抗氧化剂的发现。依达拉奉的构效关系表明，亲脂性取代基对于表现出其脂质过氧化抑制活性至关重要。体内研究表明，依达拉奉在短暂性脑缺血模型中显示出脑保护活性。
