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。

active and efficient catalyst system derived from a palladium precatalyst and monophosphine ligands 1 or 2 for the Suzuki-Miyaura cross-coupling reaction of heteroaryl boronic acids and esters has been developed. This method allows for the preparation of a wide variety of heterobiaryls in good to excellent yields and displays a high level of activity for the coupling of heteroaryl chlorides as well as

Suzuki–Miyauracoupling of heteroaryls is an important method for the preparation of compound libraries for medicinal chemistry and materials research. Although many catalysts have been developed, none of them have been generally applicable to the coupling reactions of heteroarylchlorides and tosylates at room temperature. We discovered that a catalyst combination of Pd(OAc)2 and XPhos (2-dicyclohexylphosphanyl-2′

Imidazo[1,2-b]pyridazine-based compounds of the formula (I): are disclosed, wherein R1, R2 and R3 are defined herein. Compositions comprising the compounds and methods of their use to treat, manage and/or prevent diseases and disorders mediated by mediated by adaptor associated kinase 1 activity are also disclosed.
The present invention describes 2-methyl-quinazoline compounds of general formula (I), methods of preparing said compounds, intermediate compounds useful for preparing said compounds, pharmaceutical compositions and combinations comprising said compounds, and the use of said compounds for manufacturing pharmaceutical compositions. The 2-methyl substituted quinazoline compounds of general formula(I) effectively and selectively inhibit the Ras-Sos interaction without significantly targeting the EGFR receptor. They are therefore useful for the treatment or prophylaxis of diseases, in particular of hyperproliferative disorders, such as cancer as a sole agent or in combination with other active ingredients.
