Deskripsi
A series of (<i>S</i>)-1-phenyl-3,4-dihydroisoquinoline-2(1<i>H</i>)-carboxamide derivatives was synthesized and evaluated for inhibitory activity against monoamine oxidase (MAO)-A and-B, acetylcholine esterase (AChE), and butyrylcholine esterase (BChE). Four compounds (<b>2i</b>, <b>2p</b>, <b>2t</b>, and <b>2v</b>) showed good inhibitory activity against both MAO-A and MAO-B, and two compounds (<b>2d</b> and <b>2j</b>) showed selective inhibitory activity against MAO-A, with IC<sub>50</sub> values of 1.38 and 2.48 µM, respectively. None of the compounds showed inhibitory activity against AChE; however, 12 compounds showed inhibitory activity against BChE. None of the active compounds showed cytotoxicity against L929cells. Molecular docking revealed several important interactions between the active analogs and amino acid residues of the protein receptors. This research paves the way for further study aimed at designing MAO and ChE inhibitors for the treatment of depression and neurodegenerative disorders.
