Drug development for Alzheimer's disease has one of the greatest failure rates of any therapeutic field and AD is still incurable. Glycogen synthase kinase-3β is a critical enzyme implicated in the pathogenesis of AD, particularly in the hyperphosphorylation of tau protein, which leads to the formation of neurofibrillary tangles. TNF-α also plays a significant role in the pathogenesis of Alzheimer's disease by promoting neuroinflammation, contributing to the formation of amyloid plaques and neurofibrillary tangles, impairing synaptic function, and disrupting the balance of neurotrophic factors. Phytomedicine has numerous advantages over synthetic medications, acting multiple mode of action, including being less toxic and having fewer adverse effects. Flavonoids act as a promising therapeutic target for treating Alzheimer's disease. The present work investigates the anti-AD potentials of 35 flavonoids for the inhibition of GSK-3β and TNF-α.
The physicochemical, pharmacokinetic parameters, toxicity profile and drug-likeliness of the selected 35 flavonoids were predicted using SwissADME & OSIRIS data Warrier property explorer web tool. All flavonoids were selected for docking studies on GSK-3β and TNF-α protein using Autodock 4.2.1.
The predictions of this study suggested that among the selected 35 flavonoids, Top 3 flavonoids, such as Epicatechin gallate -10.93 kcal/mol, Fisetin -9.44 kcal/mol and Eriodictyol -8.54 kcal/mol for GSK-3β targets. TNF-α Fisetin -11.52 kcal/mol, Sterubin -10.87 kcal/mol, Biochainin A -10.69 kcal/mol were compared with standard drug donepezil.
Therefore, these flavonoids could be utilized as possible leads for the structure-based design in the advancement of new, strong Anti-Alzheimer's agents. However, more and analyses are required to finally confirm the outcomes of this research.
阿尔茨海默病的药物研发在所有治疗领域中失败率极高,且该疾病仍无法治愈。糖原合酶激酶-3β是一种关键酶,与阿尔茨海默病的发病机制相关,尤其是在tau蛋白的过度磷酸化过程中起作用,这会导致神经原纤维缠结的形成。肿瘤坏死因子-α在阿尔茨海默病的发病机制中也起着重要作用,它通过促进神经炎症、促使淀粉样斑块和神经原纤维缠结的形成、损害突触功能以及破坏神经营养因子的平衡来发挥作用。植物药相较于合成药物具有诸多优势,具有多种作用模式,包括毒性较小和不良反应较少。黄酮类化合物是治疗阿尔茨海默病的一个有前景的治疗靶点。本研究调查了35种黄酮类化合物对糖原合酶激酶-3β和肿瘤坏死因子-α的抑制作用,以评估其抗阿尔茨海默病的潜力。
使用SwissADME和OSIRIS数据Warrier属性探索器网络工具预测所选35种黄酮类化合物的物理化学、药代动力学参数、毒性特征和药物相似性。使用Autodock 4.2.1对所有黄酮类化合物进行与糖原合酶激酶-3β和肿瘤坏死因子-α蛋白的对接研究。
本研究预测表明,在所选的35种黄酮类化合物中,针对糖原合酶激酶-3β靶点,排名前三的黄酮类化合物分别是表儿茶素没食子酸酯(-10.93千卡/摩尔)、漆黄素(-9.44千卡/摩尔)和圣草酚(-8.54千卡/摩尔)。针对肿瘤坏死因子-α,漆黄素(-11.52千卡/摩尔)、异甘草素(-10.87千卡/摩尔)、生物链素A(-10.69千卡/摩尔)与标准药物多奈哌齐进行了比较。
因此,这些黄酮类化合物可作为基于结构设计的潜在先导物,用于开发新型强效抗阿尔茨海默病药物。然而,需要更多的研究和分析来最终证实本研究的结果。
