Mitochondrial enzymes monoamine oxidases were thought to be an emerging and useful therapeutic target for neurodegenerative disorders. Monoamine oxidases have two isoforms, A and B. MAO-A is related with metabolism of amine neurotransmitters in the brain whereas MAO-B is concerned with aging related neurodegenerative disorders. Therefore the identification, characterization and discovery of potent MAO-A and B inhibitors is very crucial in research. A series of quinolyl-thienyl chalcones were tested against MAO-A and B. Among the screened compounds, most of them revealed potent MAO-A and B inhibition. Compound 5i presented most potent MAO-A inhibition having IC50 values 0.047 µM, while 4l showed excellent inhibitory potency against MAO-B among all the tested compound having IC50 values 0.063 µM. Molecular modelling studies were performed against human MAO-A and MAO-B for the explanation of binding site interactions.
