Synthesis and screening of a combinatorial library of naphthalene substituted chalcones: inhibitors of leukotriene B4 Original Research Article

A combinatorial mini library of naphthalene substituted chalcones has been prepared by solution phase chemistry. Screening of these mixtures for leukotriene B4 inhibitory activity using human whole blood assay (HWBL) afforded a lead compound, 1-(6-butoxy-2-naphthyl)-3-(4-nitrophenyl)-prop-2-en-1-one (K4A3) with an IC50 value of 18.5 μM.
