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.
