Potent and Selective Inhibitors of CK2 Kinase Identified through Structure-Guided Hybridization
摘要:
In this paper we describe a series of 3-cyano-5-aryl-7-aminopyrazolo[1,5-a]-pyrimidine hits identified by kinase-focused subset screening as starting points for the structure-based design of conformationally constrained 6-acetamido-indole inhibitors of CK2. The synthesis, SAR, and effects of this novel series on Akt signaling and cell proliferation in vitro are described.

A novel class of mitogen-activated protein kinase-activated proteinkinase 2 (MAPKAP-K2) inhibitors was discovered through screening a kinase-focused library. A homology model of MAPKAP-K2 was generated and used to guide the initial SAR studies and to rationalize the observed selectivity over CDK2. An X-ray crystal structure of a compound from the active series bound to crystalline MAPKAP-K2 confirmed
通过筛选激酶集中的文库,发现了一类新型的促分裂原活化蛋白激酶活化蛋白激酶2(MAPKAP-K2)抑制剂。MAPKAP-K2的同源性模型已生成,可用于指导最初的SAR研究并合理化所观察到的对CDK2的选择性。结合到晶体MAPKAP-K2的活性系列化合物的X射线晶体结构证实了预测的结合模式。这使得能够发现一系列吡唑并[1,5- a ]嘧啶衍生物,它们在抗内毒素休克的小鼠模型中作为抗TNF-α剂具有良好的体外细胞效价和体内功效。
