A new series of compounds, 1-aryl-3-(3,4-dihydro-2H-chromen-5-yl) ureas, have been synthesized and their structures were confirmed by FAB-MS and 1H NMR. The preliminary pharmacological screening showed that these compounds inhibited TNF-αproduction in lipopolysaccharide (LPS)-stimulated THP-1 cells.
