Members of the BETfamily of bromodomain containing proteins have been identified as potential targets for blocking proliferation in a variety of cancer cell lines. A two-dimensional NMR fragment screen for binders to the bromodomains of BRD4 identified a phenylpyridazinone fragment with a weak binding affinity (1, Ki = 160 μM).

to the synthesis of fluorinated o-hydroxyacetophenones in good to excellent yields is reported. We demonstrated a convenient method for replacing the iodine atom in o-iodophenols with MeC(=O)– group through the introduction and subsequent hydrolysis of TIPS–C≡C– moiety by of p-toluenesulfonic acid monohydrate. The resulting compounds may serve as precursors for the synthesis of polyfluorinated 3-ben

The present invention generally relates to a process that selectively polymerizes ethylene in the presence of an alpha-olefin, and to a metal-ligand complex (precatalyst) and catalyst useful in such processes, and to related compositions. The present invention also generally relates to ligands and intermediates useful for preparing the metal-ligand complex and to processes of their preparation.
