This paper describes recent results of a research program aimed at the synthesis and pharmacological evaluation of new 4 (1H)-pyridinone derivatives belonging to the 1, 3- disubstituted series (4–11). These compounds were structurally planned by applying the molecular hybridization strategy on previously described 1, 2-disubstituted-4 (1H)- pyridinone derivatives, considered as lead compounds, which present potent analgesic ...
