A series of chalcone analogues and some of their derivatives were synthesized and subjected to the mosquito larvicidal study. Chalcones having electron releasing group(s) on either ring A or ring B showed high toxicity. Electron withdrawing group(s), especially at ring B, reduced the activity of chalcones. The activity was abruptly decreased due to replacement of ring A by CH3, extension of conjugation or blocking of alpha,beta-unsaturated ketone part of chalcones by derivatization. Quantitative structure-activity relationship (QSAR) studies of these compounds were performed using various spatial, electronic and physicochemical parameters. Genetic Function approximation with linear and spline options was used as the chemometric tool for developing the QSAR models.
