demonstrated that brain-penetrant microtubule (MT)-stabilizing compounds, including the 1,2,4-triazolo[1,5-a]pyrimidines, hold promise as candidate treatments for Alzheimer’s disease and related neurodegenerative tauopathies. Triazolopyrimidines have already been investigated as anticancer agents; however, the antimitotic activity of these compounds does not always correlate with stabilization of MTs in cells
对 tau 和 Aβ 斑块转基因小鼠模型的研究表明,脑渗透性微管 (MT) 稳定化合物,包括 1,2,4-三唑[1,5- a]嘧啶,有望成为阿尔茨海默病和相关神经退行性 tau 蛋白病的候选治疗方法。三唑并嘧啶已作为抗癌剂进行了研究。然而,这些化合物的抗有丝分裂活性并不总是与细胞中 MTs 的稳定性相关。事实上,我们实验室以前的研究确定了在 C6 上连接的片段在确定三唑并嘧啶是否促进 MT 稳定或相反地破坏细胞中的 MT 完整性方面的关键作用。为了进一步阐明构效关系 (SAR) 并确定神经退行性疾病的潜在改善 MT 稳定候选物,设计、合成和评估了一套全面的 68 种三唑并嘧啶同系物,这些同系物在 C6 和/或 C7 处具有结构修饰。
