Abstract: Monoamine oxidase B is a crucial therapeutic target for neurodegenerative disorders like
Alzheimer's and Parkinson's since they assist in disintegrating neurotransmitters such as dopamine in
the brain. Pursuing efficacious monoamine oxidase B inhibitors is a hot topic, as contemporary
therapeutic interventions have many shortcomings. Currently available FDA-approved monoamine
oxidase inhibitors like safinamide, selegiline and rasagiline also have a variety of side effects like
depression and insomnia. In the quest for a potent monoamine oxidase B inhibitor, sizeable, diverse
chemical entities have been uncovered, including chalcones. Chalcone is a renowned structural
framework that has been intensively explored for its monoamine oxidase B inhibitory activity.The
structural resemblance of chalcone (1,3-diphenyl-2-propen-1-one) based compounds and 1,4-diphenyl-
2-butene, a recognized MAO-B inhibitor, accounts for their MAO-B inhibitory activity. Therefore,
multiple revisions to the chalcone scaffold have been attempted by the researchers to scrutinize the
implications of substitutions onthe molecule's potency. In this work, we outline the docking
investigation results of various chalcone analogues with monoamine oxidase B available in the
literature until now to understand the interaction modes and influence of substituents. Here we focused
on the interactions between reported chalcone derivatives and the active site of monoamine oxidase B
and the influence of substitutions on those interactions. Detailed images illustrating the interactions
and impact of the substituents or structural modifications on these interactions were used to support
the docking results.
