DYRK1A has emerged as a potential target for therapies of Alzheimer’s disease using small molecules. On the basis of the observation of selective DYRK1A inhibition by firefly d-luciferin, we have explored static and dynamic structural properties of fragment sized variants of the benzothiazole scaffold with respect to DYRK1A using X-ray crystallography and NMR techniques. The compounds have excellent
DYRK1A已成为使用小分子疗法治疗阿尔茨海默氏病的潜在靶标。上的由萤火虫观察选择性抑制DYRK1A的基础d-荧光素,我们已经使用X射线晶体学和NMR技术探索了DYRK1A的苯并噻唑支架片段大小变异体的静态和动态结构特性。这些化合物具有出色的配体效率,并在动态平衡中显示出显着的结合模式多样性。结合的几何形状部分取决于通常被认为是“弱”的相互作用,包括以“ F-CO”,“硫-芳族”和“卤素-芳族”相互作用为代表的“正交多极”类型,以及通过改变氢键而调节的氢键。吸电子基团。这些研究表明,苯并噻唑支架对于治疗性DYRK1A抑制剂的开发具有很高的前景。此外,绑定互动的微妙之处包括动力学,
