Abstract<\/strong>
Human monoamine oxidases (hMAOs) are mitochondrial flavoenzymes that break down amines and regulate neurotransmitters such as serotonin, dopamine, and norepinephrine. Two isoforms have been identified in humans, namely hMAO-A and hMAO-B, which differ in their activity, tissue distribution and substrate specificity. The selective inhibition of the B isoform represents a kay strategy in the management of neurodegenerative disorders, including Parkinson\u2019s disease1<\/sup>. Previous studies showed that benzo[b<\/em>]thiophen-3-ol derivatives act as selective hMAO-B inhibitors, exhibiting neuroprotective profile in ex-vivo models2<\/sup>. With the aim of investigating the potential of this scaffold, two series of benzo[b<\/em>]thiophen-3-ol derivatives, benzylated (Library 1, Figure 1<\/strong>) and acetylated (Library 2, Figure 1<\/strong>), were designed and evaluated for their inhibitory activity in this study. Acetylated compounds were generally strong hMAO inhibitors but lacked selectivity, affecting both hMAO-A and hMAO-B. In contrast, benzylated compounds showed activity and selectivity depending on the type and position of substituents on the aromatic ring. These findings highlight the critical role of structural modifications in modulating isoform selectivity and support the further optimization of benzylated derivatives as promising hMAOs inhibitors.
