Kinase inhibitions in pyrido[4,3-h] and [3,4-g]quinazolines: Synthesis, SAR and molecular modeling studies
摘要:
New pyrido[3,4-g]quinazoline derivatives were prepared and evaluated for their inhibitory potency toward 5 protein kinases (CLK1, DYRK1A, GSK3, CDK5, CK1). A related pyrido[4,3-h]quinazoline scaffold with an angular structure was also synthesized and its potency against the same protein kinase panel was compared to the analogous pyrido[3,4-g] quinazoline. Best results were obtained for 10-nitropyrido[3,4-g]quinazoline 4 toward CLK1 with nanomolar activities.
发现作为CMGC家族蛋白激酶抑制剂的吡啶并[3,4- g ]喹唑啉衍生物:设计,合成,抑制潜能和X射线共晶结构
摘要:
描述了新的吡啶并[3,4- g ]喹唑啉衍生物的设计与合成及其对五个CMGC家族成员(CDK5,CK1,GSK3,CLK1和DYRK1A)的蛋白激酶抑制能力。对于这种原始的三环杂芳族骨架作为CLK1 / DYRK1A活性的调节剂的兴趣已通过纳摩尔浓度(化合物12和13)验证。具有两种抑制剂的CLK1共晶体结构揭示了这些化合物在ATP结合口袋中的结合模式。
The synthesis of new diversely substituted pyrido[3,4-g]quinazolines is described. The inhibitory potencies of prepared compounds toward a panel of five CMGC protein kinases (CDK5, CLK1, DYRK1A, CK1, GSK3), that are known to play a potential role in Alzheimer's disease, were evaluated. The best overall kinase inhibition profile was found for nitro compound 4 bearing an ethyl group at the 5-position
Discovery of pyrido[3,4-g]quinazoline derivatives as CMGC family protein kinase inhibitors: Design, synthesis, inhibitory potency and X-ray co–crystal structure
The design and synthesis of new pyrido[3,4-g]quinazoline derivatives is described as well as their protein kinase inhibitorypotencies toward five CMGC family members (CDK5, CK1, GSK3, CLK1 and DYRK1A). The interest for this original tricyclic heteroaromatic scaffold as modulators of CLK1/DYRK1A activity was validated by nanomolar potencies (compounds 12 and 13). CLK1 co–crystal structures with two
