Potential Roles of microRNAs in the Regulation of Monoamine Oxidase A in the Brain

Frontiers in Molecular Neuroscience, 2018
Monoamine oxidase A (MAO-A) is an enzyme that regulates the levels of monoamine neurotransmitters, such as serotonin, noradrenaline and dopamine and it has been used as a therapeutic target for depression.

Synthesis and in vitro evaluation of pteridine analogues as monoamine oxidase B and nitric oxice synthase inhibitors

, 2009
Monoamine oxidase B (MAO-B) and nitric oxide synthase (NOS) have both been implicated in the pathology of neurodegenerative diseases. In an attempt to design dual-target-directed drugs that inhibit both these enzymes, a series of pteridine-2,4-dione ...

Unraveling the Physicochemical Landscape of Organoselenium Compounds in Nanocarrier Systems

The Chemical Record, EarlyView.
Main nanocarriers employed to enhance the bioavailability and transport of organoselenium compounds. The image illustrates the key interaction forces that stabilize these organoselenium species in solution, enabling their application in drug delivery systems, catalysis, photoelectronic devices, and sensing technologies. In recent years, publications on

Dopamine: The Essential Bridge Mediating Obstructive Sleep Apnea and Hippocampus‐Dependent Learning and Memory Impairments

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Obstructive sleep apnea is a clinical syndrome that triggers a series of pathophysiologic changes, including disturbed sleep architecture, chronic intermittent hypoxia and hypercapnia, and ultimately severe cognitive dysfunction. The hippocampus plays a key role in various cognitive processes such as learning and memory.

Rutamarin: Efficient Liquid–Liquid Chromatographic Isolation from Ruta graveolens L. and Evaluation of Its In Vitro and In Silico MAO-B Inhibitory Activity

Molecules, 2020
Naturally occurring coumarins are a group of compounds with many documented central nervous system (CNS) activities. However, dihydrofuranocoumarins have been infrequently investigated for their bioactivities at CNS level. Within the frame of this study,

Recent development of monoamine oxidase inhibitors

, 2005
The monoamine oxidases (MAO-A and MAO-B) are flavoenzymes located in the outer mitochondrial membrane responsible for the oxidative deamination of many endogenous and exogenous monoamines.

Structural basis of regioselective double halogenation of the β‐carboline tryptoline by the single‐component halogenase AetF

Acta Crystallographica Section D, EarlyView.
A structure of the flavin‐dependent single‐component tryptophan halogenase AetF bound to the non‐native tricyclic substrate tryptoline reveals a binding pose analogous to l‐tryptophan that directs C6‐first halogenation. Product analysis identifies 6,8‐dibromotryptoline as the final product.Flavin‐dependent halogenases (FDHs) offer a biocatalytic route ...

Kaempferol Protects Intestinal Health in Chinese Forest Musk Deer Possibly by Regulating Intestinal Microbiota and Inhibiting the NF‐κB/NLRP3 Signaling Pathway

Integrative Zoology, EarlyView.
Kaempferol modulates the tryptophan metabolism pathway by increasing the abundances of Christensenellaceae R7 group, Bacteroides, and Blautia and reducing that of Rikenellaceae RC9 gut group, thereby significantly increasing the levels of ILA and IAA. This process inhibits the activation of NF‐κB/NLRP3 signaling pathway, reduces pro‐inflammatory factor

Monoamine oxidase in neuronal cell death

, 2008
Monoamine oxidase (MAO) is an oxidative enzyme that deaminates a variety of amine substrates, including the neurotransmitter dopamine. The enzymatic reaction requires molecular oxygen and produces hydrogen peroxide as a by-product.
