Alzheimer's disease and Down syndrome. In this study, we present the design, synthesis, and biological evaluation of indirubins as DYRK inhibitors with enhanced selectivity. Modifications of the bis-indole included polar or acidic functionalities at positions 5' and 6' and a bromine or a trifluoromethyl group at position 7, affording analogues that possess high activity and pronounced specificity. Compound 6i
DYRK激酶参与替代性的前mRNA剪接以及神经病理状态,例如阿尔茨海默氏病和唐氏综合症。在这项研究中,我们提出了靛蓝素作为DYRK
抑制剂的设计,合成和
生物学评估,具有增强的选择性。双
吲哚的修饰包括在5'和6'位具有极性或酸性官能团,在7位具有
溴或三
氟甲基基团,从而提供了具有高活性和明显特异性的类似物。带有5'-
羧酸根部分的化合物6i表现出最好的抑制特性。通过分子建模提出了一种新型的反向结合模式,该模式为选择性的提高奠定了基础,并通过确定与6i配合的DYRK2的晶体结构得到了证实。
