diseases, making CLK1 and DYRK1A important therapeutic targets. Here we describe the synthesis of new pyrido[3,4-g]quinazoline derivatives and the evaluation of the inhibitory potencies of these compounds toward CDK5, CK1, GSK3, CLK1 and DYRK1A. Introduction of aminoalkylamino groups at the 2-position resulted in several compounds with low nanomolar affinity and selective inhibition of CLK1 and/or DYRK1A
Cdc2样激酶1(CLK1)和酪氨酸磷酸化双特异性调节激酶1A(DYRK1A)参与了替代性的前mRNA剪接的调节。该过程的失调与癌症进展和神经退行性疾病有关,这使CLK1和DYRK1A成为重要的治疗靶标。在这里,我们描述了新的吡啶基[3,4- g]喹唑啉衍生物及其对CDK5,CK1,GSK3,CLK1和DYRK1A的抑制作用评估。在2位上引入氨基烷基氨基会产生几种具有低纳摩尔亲和力且对CLK1和/或DYRK1A具有选择性抑制的化合物。他们对几种永生或癌细胞系的评估显示了不同程度的细胞活力降低。CLK1与两种最有效化合物的共晶体结构揭示了吡啶并[3,4- g ]喹唑啉支架的两种替代结合模式,可用于未来的抑制剂设计。
