**Background**
Monoamine oxidase (MAO) enzymes, specifically MAO-A and MAO-B, play a critical role in the oxidative deamination of various biogenic amines in the brain and peripheral tissues. MAO-B is primarily associated with the breakdown of dopamine and is frequently targeted in the research of neurodegenerative disorders, such as Parkinson’s disease, where the preservation of dopaminergic neurons is essential. Additionally, the inhibition of acetylcholinesterase (AChE) is a well-established strategy for improving cognitive function in Alzheimer’s disease. Developing compounds that can selectively inhibit MAO-B over MAO-A, or provide dual inhibition of MAO-B and AChE, represents a promising therapeutic approach for treating complex neurological conditions. In this context, we will introduce a chalcone derivative – 4-Chlorochalcone.
**Definition**
4-Chlorochalcone is a chalcone derivative that acts as a potent and selective inhibitor of human monoamine oxidase-B (hMAO-B) with an IC50 value of 0.082 μM.
**In Vitro Studies**
Regarding the 4-Chlorochalcone biological activity, this compound demonstrates high selectivity for the B-isoform of monoamine oxidase. In vitro assays indicate that while it strongly inhibits hMAO-B (IC50 = 0.082 μM), it exhibits significantly lower potency against hMAO-A, with an IC50 value of 9.95 μM. Beyond its MAO inhibitory effects, 4-Chlorochalcone in vitro studies have revealed that the compound also possesses inhibitory activity against cholinesterase, specifically inhibiting AChE with an IC50 of 2.79 μM. Based on the 4-Chlorochalcone technical information, the compound has a molecular weight of 242.70 and a chemical formula of C15H11ClO. In conclusion, 4-Chlorochalcone is a selective MAO-B inhibitor that also exhibits inhibitory activity against AChE, making it a valuable tool for neuroscience research.
