The latter is particularly important in conditions such as Parkinson's disease, where a dopamine precursor is used to treat disease symptoms and highlights that the fate of MAO-A containing dopaminergic neurons may depend on both MAO-A levels and catecholamine substrate availability.
Nowadays, therapeutic attention on MAOIs engrosses two imperative categories; MAO-A inhibitors, in certain mental disorders such as depression and anxiety, and MAO-B inhibitors, in neurodegenerative disorders like Alzheimer's disease (AD) and Parkinson's disease (PD).
Significant binding affinity of ursolic acid was seen with MAO-A, which indicated its potential role in other neurological disorders, for example, Alzheimer's disease and Parkinson disease besides depression.
The bis-iminothiazolidinone compounds were investigated in vitro for their inhibition of monoamine oxidase (MAO-A & MAO-B) enzymes with the aim to identify new and distinct pharmacophores for the treatment of neurodegenerative disorders like Parkinson's disease.
The findings suggest compounds 4 and 11 be considered as new potent and reversible MAO-A inhibitors or useful lead compounds for the developments of MAO inhibitors for the treatment of disorders like depression, Parkinson's disease and Alzheimer disease.
Polymorphisms of COMT (c.649G>A), MAO-A (c.1460C>T), NET (c.1287G>A) Genes and the Level of Catecholamines, Serotonin in Patients with Parkinson's Disease.
Simultaneous determination of MAO-A and -B activity following first time intake of an irreversible MAO-B inhibitor in patients with Parkinson's disease.
The aim of this study was to determine the effectiveness of eckol and dieckol isolated from the methanolic extract of E. bicyclis against PD by the inhibition of human MAO-A and MAO-B (hMAO-A and hMAO-B).
We investigate power and type I error rate of the likelihood-based test, using simulated data and apply our method to marker data from the monoamine oxidase A&B genes in families with Parkinson disease.
Two distinct forms of enzyme, encoded by genes MAOA and MAOB located on the X chromosome, have been considered as possible factors in the pathogenesis of Parkinson disease (PD).
We tested for gender-specific interactions between smoking and genetic polymorphisms of monoamine oxidase B (MAO-B) intron 13 (G or A allele), monoamine oxidase A (MAO-A) EcoRV (Yor N allele), and dopamine D2 recepor (DRD2) Taq1B (B1 or B2 allele) in a case-control study of 186 incident idiopathic Parkinson's disease (PD) cases and 296 age- and gender-matched controls.
Thus, the 5HTTLPR but not the MAOA gene promoter-associated polymorphism may be a risk factor for depression in PD patients, while neither polymorphism increases the risk for development of Parkinson's disease itself.
The EcoRV genetic polymorphism of human monoamine oxidase type A is not associated with Parkinson's disease and does not modify the effect of smoking on Parkinson's disease.
In the present study, disruption of the MAOA gene was evaluated in males with mental retardation with and without a history of sexually deviant behavior, as well as normal controls, healthy males, and patients with other diseases (Parkinson disease, Lesch-Nyhan syndrome).
