Learning and memory deficits in Alzheimer’s disease (AD) result from synaptic failure and neuronal loss, the latter caused in part by excitotoxicity and oxidative stress. A therapeutic approach is described that uses NO-chimeras directed at restoration of both synaptic function and neuroprotection. 4-Methylthiazole (MZ) derivatives were synthesized, based upon a lead neuroprotective pharmacophore acting
阿尔茨海默病 (AD) 的学习和记忆缺陷由突触衰竭和神经元丢失引起,后者部分由兴奋性毒性和氧化应激引起。描述了一种治疗方法,它使用 NO 嵌合体来修复突触功能和神经保护。合成了 4-甲基噻唑 (MZ) 衍生物,基于部分由 GABA A起作用的先导神经保护药效团受体增强。分析了 MZ 衍生物对初级神经元的保护作用,使其免受氧-葡萄糖剥夺和兴奋性毒性的影响。选定的神经保护衍生物被纳入 NO 嵌合体前药,创造了诺美噻唑。为了提供诺美噻唑药物类别的概念证明,对选定的例子进行了分析,以恢复 AD 转基因小鼠海马切片中的突触功能,逆转认知缺陷,以及前药及其神经保护性 MZ 代谢物的脑生物利用度。总之,分析数据表明这些嵌合诺美噻唑可用于治疗神经退行性疾病的多种成分,例如 AD。
