The syntheses of the fluorescent 5 and 6 used in the assay are reported as well as Kd results for 10 compounds, including JNJ7706621, NVP-BSK805, and filgotinib (GLPG0634). X-ray crystal structures of JAK2 JH2 in complex with NVP-BSK805, filgotinib, and diaminopyrimidine 8 elucidate the binding poses.
据报道,竞争性荧光偏振(FP)测定法可确定探针分子与假激酶JAK2 JH2变构位点的结合亲和力。报告了测定中使用的荧光5和6的合成以及10种化合物(包括JNJ7706621,NVP-BSK805和filgotinib(GLPG0634))的Kd结果。与NVP-BSK805,filgotinib和diaminopyrimidine 8配合使用的JAK2 JH2的X射线晶体结构阐明了结合姿势。
