    • The neuroprotective multifunctional antioxidants are compounds that contain a 2-diacetylamino-5-hydroxypyrimidine moiety, having the structural formula: wherein R1 is CH2 or C2H4; R2 is H or —OR4 where R4 is H or aryl; and R3a and R3b are independently selected from the group consisting of H and —O-alkyl. The antioxidants are orally bioavailable metal-attenuating multifunctional antioxidants that can independently attenuate transition metals, as well as scavenger free radicals. The multifunctional antioxidant compounds, by their ability to independently chelate metals, such as Fe, Cu or Zn, and scavenge free radicals generated from different sources, are neuroprotective and are beneficial for the treatment of various neurological disorders, such as Alzheimer's disease, Parkinson's disease, ALS, traumatic brain injury, ocular disorders, such as cataract, glaucoma, age-related macular degeneration and other retinal degeneration, as well as for reducing the progression of diabetic complications.
    • 神经保护性多功能抗氧化剂是含有2-二乙酰氨基-5-羟基嘧啶部分的化合物,其具有以下结构式:其中R1是CH2或C2H4; R2是H或-OR4,其中R4是H或芳基; R3a和R3b独立地选自H和-O-烷基。 抗氧化剂是口服生物可利用的金属减弱多功能抗氧化剂,可以独立减弱过渡金属以及清道夫自由基。 多功能抗氧化剂通过独立地螯合金属(如Fe,Cu或Zn)和清除不同来源产生的自由基的能力是神经保护性的,并且有益于治疗各种神经障碍,例如阿尔茨海默病,帕金森病 ,ALS,创伤性脑损伤,眼部疾病如白内障,青光眼,年龄相关性黄斑变性和其他视网膜变性,以及用于减少糖尿病并发症的进展。
