- JAK2 JH2 Fluorescence Polarization Assay and Crystal Structures for Complexes with Three Small Molecules
-
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.

- PROCESS FOR THE PRODUCTION OF ETRAVIRINE
-
A novel process for the preparation of Etravirine comprises the condensing of ethyl cyanoacetate with N-cyanophenylguanidine to obtain an —OH compound of formula (II), which is further converted to a leaving group of formula (III). The compound of formula (III) is optionally protected and brominated to yield compound of formula (IV). The condensation of formula (IV) with 3,5-dimethyl-4-hydroxybenzonitrile yields a compound of formula (VI), and an optional deprotection of the compound of formula (VI) results in Etravirine.
