Two chalcones (4a, 4b) and nine Schiff bases (4c – 4k) of 7-hydroxy-3-formyl chromen-4-one have been synthesized. All the synthesized compounds 1–18 were screened for their hMAO (human Mono Amine Oxidase) inhibitory activity using recombinant human MAO isoforms. hMAO inhibitory activity was determined by measuring the production of H2O2 from p-tyramine, the common substrate for both hMAO-A and hMAO-B, using the Amplex1-RedMAO assay kit. The compounds and reference inhibitors did not react directly with the Amplex1-Red reagent indicating that they do not interfere with the measurements. The compounds were also confirmed, as they did not interact with resorufin by treating the maximum concentration of compounds with various concentrations of resorufin in order to detect if the fluorescence signal is the same with or without our compounds in the medium. No significant quenching of resorufin was observed.
