COX‐2 inhibitors on depressive symptoms and the desirable physicochemical and biological properties of the morpholine group, a series of novel 2‐(2‐arylmorpholino)ethylesters of ibuprofenhydrochlorides were designed, synthesized, and tested for their COX‐2 inhibitory and serotoninreuptake inhibitory activities in vitro. The structure–activity relationships of the 2‐(2‐arylmorpholino)ethyl esters
