33 µM). Molecular docking studies of these molecules revealed high-affinity binding to several amino acids of BACE1, which are essential for efficient inhibition. These results demonstrate that 1,2,4-triazine derivatives bearing an aryl phenoxy methyl-1,2,3-triazole have promising properties as therapeutic agents for AD.
阿尔茨海默氏病(AD)是一种复杂的神经系统疾病,具有多种潜在的病理过程。几条证据表明,BACE1是AD发病机理中的关键酶,其抑制作用在AD治疗中尤为重要。合成了十个带有芳基苯氧基甲基-1,2,3-三唑侧基的新的3-肼基-1,2,4-三嗪作为抗AD的多功能配体。我们表明,在苯环对位含有Cl和NO2基团的化合物,即化合物7c(IC50 = 8.55±3.37 µM)和7d(IC50 = 11.42±2.01 µM),具有有希望的BACE1抑制潜力。此外,我们评估了PC12神经元细胞系中7c和7d衍生物的神经保护活性,它们对淀粉样β肽毒性显示出中度保护作用。此外,化合物7d表现出金属螯合活性和适度的抗氧化电位(IC50 = 44.42±7.33 µM)。这些分子的分子对接研究表明与BACE1的多个氨基酸具有高亲和力结合,这对于有效抑制至关重要。这些结果表明,带有芳基苯氧基甲基-1,2,3-三唑的1
