Abstract A series new 2H-chromene-3-carboxamide derivatives 4a–4t were synthesized and evaluated as monoamine oxidase A and B (MAO-A and MAO-B) inhibitors. Among them, compound 4d (IC 50= 0.93 μM, IC 50 iproniazid= 7.80 μM) showed the most activity and higher MAO-B selectivity (64.5-fold vs. 1-fold) with respect to the MAO-A isoform. The active compound 4d was also docked into the hMAO-B complex structure active site to determine ...
