Summary: A library of piperonylic acid-derived hydrazones with variable aryl moiety was synthesized and investigated for their multifunctional properties against cholinesterases and monoamine oxidases. The results showed that the tested hydrazones exhibited excellent cholinesterase inhibition profile. The compound 4i showed promising dual inhibitory profile against AChE, BChE, and MAO-B enzymes. Kinetic studies revealed that compound 4i reversibly inhibited AChE enzyme in a competitive manner, while it displayed a non-competitive and reversible inhibition profile against MAO-B. Molecular docking studies and atomistic simulation confirmed the stable association of compound 4i within the active sites of AChE and MAO-B.

Summary: In this study, N-methyl-piperazine chalcones were synthesized and evaluated for their inhibitory activities against target enzymes involved in depression and neurodegenerative diseases. Compound 2k showed the highest selective inhibition against MAO-B, followed by compound 2n. Both compounds also effectively inhibited AChE, indicating multi-target inhibitory modes. Compound 2o exhibited significant inhibitions over MAO-B, AChE, and BChE. Compounds 2k and 2n showed low cytotoxicity and are predicted to possess favorable pharmacokinetic properties.

Summary: A new series of 2-phenylbenzofuran derivatives were designed and synthesized to investigate their MAO inhibitory activity and selectivity. The presence of methoxy substituents in the 2-phenyl ring and nitro groups at positions 5 or 7 on the benzofuran moiety affected the affinity for MAO-A or MAO-B. Experimental results showed 2-(3-methoxyphenyl)-5-nitrobenzofuran 9 as the most potent MAO-B inhibitor and 7-nitro-2-phenylbenzofuran 7 as the most potent MAO-A inhibitor in this series, with methoxy groups on the 2-phenyl ring playing a key role in inhibitory activity.
