Design of novel and potent cPLA2α inhibitors containing an α-methyl-2-ketothiazole as a metabolically stable serine trap
摘要:
We report the design of novel, potent cPLA(2)alpha inhibitors that possess an alpha-methyl-2-ketothiazole that acts as a serine-reactive moiety. We describe the optimization of the series for potency and metabolic stability towards ketone reduction. This was achieved by attenuating the reactivity of the ketone using a combination of electronic and steric effects. (C) 2011 Elsevier Ltd. All rights reserved.

Provided is a thermally stable bisphenol composition whose increase in the Hazen color number is suppressed even under higher temperature conditions. A bisphenol composition including an aryl alkyl sulfide or a dialkyl disulfide at 0.1 ppb by mass to 1% by mass with respect to a bisphenol. A bisphenol composition including an aryl alkyl sulfide or a dialkyl disulfide at a predetermined ratio is thermally stable in terms of the Hazen color number, and shows no coloring problem under high temperature conditions. By using such a bisphenol composition, a polycarbonate resin having an excellent color tone can be produced.
Compounds of formula (I) are disclosed, processes for their preparation, pharmaceutical compositions containing the compounds and the use of the compounds as pharmaceuticals. There are also provided chemical intermediates useful for the preparation of the compounds. The compounds are useful as pharmaceuticals, especially for the treatment of inflammatory disease.

significantly reduced by air and moisture sensitivity, as well as harsh reaction conditions. Herein, we report four highly air- and moisture-stable well-defined mononuclear and bridged dinuclear α-diimine Ni(II) and Pd(II) complexes for C–S cross-coupling. Various ligand frameworks, including acenaphthene- and iminopyridine-based ligands, were employed, and the resulting steric properties of the catalysts were
