Provided that when X is -NR 8-, then X + R 2 is 3 - 8-membered ring, which contains at least hetero atom and is optionally substituted. R 3 and the sulfoximine residue bound at neighboring positions of Q. Full Definitions are given in the DEFINITIONS (Full Definitions) section. An independent claim is included for preparation of pyrimidine (I).

No biological data given. MECHANISM OF ACTION : Kinase (CDK, Aurora A, Aurora B, Aurora C, Tie-2, ITK and Tyk-2) inhibitor. ITK kinase inhibitory activity of (RS)-S-{2-bromo-4-[(4-{[(R)-1-(hydroxymethyl)propyl]amino}-5-(2-thienyl)pyrimidine-2-yl)amino]phenyl}-N-(ethoxycarbonyl)-S-methylsulfoximide (IA) was tested employing the ITK HTRF assay. N-terminal 6 His-tagged recombinant kinase domain of the human ITK (amino acids 352-617) expressed in baculovirus infected SF21 cells was incubated for 15 min at 22[deg]C in the presence compound (IA) in assay buffer (containing 8 mM 3-N-morpholino propane sulfonic acid/sodium hydroxide (NaOH) pH 7.0, 10 mM magnesium acetate, 0.2 mM ethylene diamine tetraacetic acid (EDTA), 1.0 mM dithiothreitol, 0.1 mM sodium ortho-vanadate, 10 mu M adenosine-tri-phosphate (ATP), 0.5 mu M biotinylated phosphorylated substrate, Tween20 (RTM: surfactant) (0.07 vol./vol.%), dimethylsulfoxide (1 vol./vol.%) (5 mu l). The mixture was further incubated for 1 h at 22[deg]C with a solution of HTRF detection reagents (40 nM streptavidine-XLent and 2.4 nM PT66-Eu-Chelate (RTM: europium-chelate labeled anti-phospho-tyrosine antibody) (5 mu l) in an aqueous EDTA-solution (100mM EDTA, bovine serum albumin (0.2 wt./vol%) in 50 mM 4-(2-hydroxyethyl)-1-piperazine ethanesulfonic acid/NaOH pH 7.0). The binding of the biotinylated phosphorylated substrate to the streptavidine-XLent and the PT66-Eu-Chelate was determined by measurement of the fluorescence emissions at 620 nm and 665 nm after excitation at 350 nm, and IC 5 0 value was calculated. The compound (IA) showed IC 5 0 value of 0.4 mu M.
