Discovery of a highly potent series of oxazole-based phosphodiesterase 4 inhibitors.
Substituted quinolyl oxazoles were discovered as a novel and highly potent series of phosphodiesterase 4 (PDE4) inhibitors. Structure-activity relationship studies revealed that the oxazole core, with 4-carboxamide and 5-aminomethyl groups, is a novel PDE4 inhibitory pharmacophore. Selectivity profiles and in vivo biological activity are also reported.
