BACKGROUND Rasagiline, a new drug developed to treat Parkinson's disease, is known to inhibit monoamine oxidase B. However, its metabolite R-(-)-aminoindan does not show this kind of activity. The present series of in vitro experiments using the rat hippocampal slice preparation deals with effects of both compounds on the pyramidal cell response after electric stimulation of the Schaffer Collat...

This report describes a sensitive and specific high-performance liquid chromatography-atmospheric pressure chemical ionization-tandem mass spectrometry method for the detection of subnanogram concentrations of selegiline and its three principle metabolites, N-desmethylselegiline, methamphetamine, and amphetamine, in human plasma. The assay has a dynamic range of 0.1-20 ng/mL for selegiline and ...

Objective The aim of this study was to assess quantitatively the gait disorders in the daily lives of patients with Parkinson's disease (PD) using with a newly developed portable gait rhythmogram (PGR), which has a trunk-mounted acceleration sensor and automatic gait-detection algorithm. Methods Using the PGR, we recorded the daily walking profiles of 14 PD patients before and after the addit...

Objective—To evaluate the correlation between changes in platelet monoamine oxidase type B (MAO-B) activity and plasma â-phenylethylamine (PEA) concentrations in patients with Parkinson’s disease and controls. Methods—Platelet MAO-B activity and plasma PEA were measured with gas chromatography-mass spectrometry (GC-MS) in patients with Parkinson’s disease treated with levodopa (12 men and 12 wo...

The FT-IR and FT-Raman vibrational spectra of selegiline were recorded. The optimized geometry and wavenumbers in the ground state were calculated using density functional (B3LYP) method with standard 6-31G(d,p) basis set. The computed B3LYP/6-31G(d,p) results show the best agreement with the experimental values over the other methods. Natural bond orbital analysis of selegiline is also carried...

background: adult stem cells (asc) are undifferentiated cells found throughout the body. these cells are promising tools for cell replacement therapy in neurodegenerative disease. adipose tissue is the most abundant and accessible source of asc. this study was conducted to evaluate effect of selegiline on differentiation of adipose-derived stem cells (adsc) into functional neuron-like cells (nl...

A single dose of isatin (indole-2,3-dione)(i.p.), an endogenous MAO inhibitor, significantly increased norepinephrine and 5-hydroxytryptamine concentrations in the rat brain and also significantly increased acetylcholine and dopamine (DA) levels in the rat striatum. Urinary isatin concentrations in patients with Parkinson's disease tend to increase according to the severity of disease. We have ...

Alzheimer is a progressive neurodegenerative disorder in which Oxidative stress plays a major role. The present study was designed to investigate Neuroprotective effect of Lornoxicam, Selegiline and co-administration of both drugs in Scopolamine induced cognitive impairment and neurodegeneration. Scopolamine (1.4mg/kg) was administered intraperitoniallyin male Wistar rats. Rectangular maze perf...

Parkinson's disease (PD) is a long term disorder affects the central nervous system and we aim to determine the relative efficacy of the current available drugs used in PD. Firstly, we performed a systematic review in current literature and eligible studies were retrieved from online databases, relevant data were extracted. Efficacy of these medications was assessed by different Unified Parkins...

Stress detrimentally affects the brain and body and can lead to or be accompanied by depression. Although stress and depression may contribute to each other, the exact molecular mechanism underlying the effects is unclear. However, there is a correlation between stress and an increase in glucocorticoid secretion which causes a subsequent increase in monoamine oxidase (MAO) activity during stres...
