Methods have been developed for the synthesis of new 1H-benzotriazol-1-ylmethyl- and 1H-imidazol-1-ylmethyl-substituted chalcones starting from 2-hydroxyacetophenone. The procedures include chloromethylation, N-alkylation, and Claisen-Schmidt condensation. The presence of an imidazole fragment on the ring A and piperazine fragment on the ring B of the resulting chalcones increases their antimicrobial activity (minimum inhibitory concentration 12.5-50.0 mu g/mL), whereas introduction of a benzotriazole fragment reduces the antimicrobial activity.
