Alzheimer's disease (AD) is caused by plaque agglomeration and entanglement in several areas of the neural cells, which leads to apoptosis. The main etiology of AD is senile dementia, which is linked to amyloid-beta (Aβ) deregulation and tau perivascular pathogeny. Hyperphosphorylated tau has a propensity for microtubules, which elevate the instability and tau-protein congregates, leading to accumulation of neurofibrillary tangles (NFTs). Tau hyperphosphorylation is susceptible to GSK-3, which has led to an emerging hypothesis regarding the pathogenesis of AD. Accordingly, attempts have been made to conduct investigations and achieve further advancements on new analogues capable of inhibiting the GSK-3 protein, which are currently in the clinical trials. In this analysis, we have evaluated certain GSK-3 inhibitor variants utilising scaffolding and framework devised techniques with pharmacological characteristics, accompanied by computational screenings (pharmacokinetics and docking). The structure-based designed analogues interacted effectively with the active amino acids of GSK-3β target protein. The in silico pharmacokinetic studies revealed their drug-like properties. The analogues with best interactions and binding scores will be considered in the future to completely demonstrate their potential relevance as viable GSK-3 inhibitors.
阿尔茨海默病(AD)是由神经细胞多个区域的斑块聚集和缠结引起的,这会导致细胞凋亡。AD的主要病因是老年痴呆症,它与β-淀粉样蛋白(Aβ)失调和tau血管周围病变有关。过度磷酸化的tau倾向于与微管结合,这会提高微管的不稳定程度,并且tau蛋白聚集,导致神经原纤维缠结(NFTs)的积累。tau过度磷酸化易受糖原合成酶激酶-3(GSK-3)影响,这导致了一个关于AD发病机制的新假说。因此,人们已经尝试对能够抑制GSK-3蛋白的新类似物进行研究并取得进一步进展,这些类似物目前正处于临床试验阶段。在本分析中,我们利用具有药理学特性的支架和骨架设计技术,并结合计算筛选(药代动力学和对接),评估了某些GSK-3抑制剂变体。基于结构设计的类似物与GSK-3β靶蛋白的活性氨基酸有效相互作用。计算机模拟药代动力学研究揭示了它们的类药物性质。未来将考虑具有最佳相互作用和结合分数的类似物,以充分证明它们作为可行的GSK-3抑制剂的潜在相关性。
