We describe herein the synthesis and neuroprotective capacity of an array of 31 compounds comprising quinolyloximes, quinolylhydrazones, quinolylimines, QNs, and related heterocyclic azolylnitrones. Neuronal cultures subjected to oxygen-glucose deprivation (OGD), as experimental model for ischemic conditions, were treated with our molecules at the onset of recovery period after OGD and showed that
我们在本文中描述了31种化合物的合成和神经保护能力,该31种化合物包括喹啉基肟,喹啉基,、喹啉,QN和相关的杂环偶氮基亚硝基。作为缺血性疾病的实验模型,对经历过氧葡萄糖剥夺(OGD)的神经元培养物在OGD后恢复期开始时用我们的分子进行了处理,结果显示,这些QN中的大多数(但不是偶氮分子)改善了神经元的生存能力24恢复后h。特别地,显示出QN(Z)-N-叔丁基-1-(2-氯-6-甲氧基喹啉-3-基)甲亚胺氧化物(23)是非常有效的神经保护剂。基于QN 23捕获不同类型的有毒自由基氧合物种的能力进行的抗氧化剂分析支持并证实了其强大的神经保护能力。最后,
