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
