Beta amyloid peptide is widely studied due to its association with Alzheimer disease (AD). Various study reported that the accumulation of beta amyloid in brain cells leads to Alzheimer disease. Hence, Beta amyloid peptide could be a potential target of anti-AD therapy. Hence, it is of interest to develop potent inhibitors for Beta amyloid peptide in the context of Alzheimer disease (AD). We report the binding features of Ascorbic acid, Cysteine, Dithioerythriol, Dithiothreitol, Malic acid and α-Tocopherol with beta amyloid having binding energy values of -6.7, -6.5, -6.0, -6.5, -6.7 and - 7.0 kcal/mol respectively. The molecular docking of top-scoring compounds with beta amyloid suggests that amino acids such as ASP23, GLU22, Phe19, are crucial in binding. Molecular dynamics simulation study showed steady-state interaction of compounds with beta amyloid for further consideration.
β淀粉样肽因其与阿尔茨海默病(AD)的关联而受到广泛研究。各种研究报告称,β淀粉样蛋白在脑细胞中的积累会导致阿尔茨海默病。因此,β淀粉样肽可能是抗AD治疗的潜在靶点。因此,在阿尔茨海默病(AD)的背景下开发针对β淀粉样肽的有效抑制剂具有重要意义。我们报告了抗坏血酸、半胱氨酸、二硫赤藓糖醇、二硫苏糖醇、苹果酸和α-生育酚与β淀粉样蛋白的结合特征,其结合能值分别为-6.7、-6.5、-6.0、-6.5、-6.7和-7.0 kcal/mol。得分最高的化合物与β淀粉样蛋白的分子对接表明,ASP23、GLU22、Phe19等氨基酸在结合中至关重要。分子动力学模拟研究表明,化合物与β淀粉样蛋白的稳态相互作用值得进一步研究。
