Abstract:

A competitive fluorescence polarization (FP) assay is reported for determining binding affinities of probe molecules with the pseudokinase JAK2 JH2 allosteric site. 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.
