Ropinirole, a recent introduction in the clinical treatment of Parkinson's disease, suffers with the problems of low oral bioavailability and frequent dosing. An effective transdermal nano-emulsion drug delivery system can however resolve these issues effectively with greater therapeutic benefits and

Excitotoxins L-beta-oxalyl-amino-alanine (L-BOAA) and 3,4,6-trihydroxyphenylalanine (6-OH-DOPA) have been investigated with regard to their potency to inhibit [3H] alpha-amino-3-hydroxy-5-methyl-4- isoxazole-propionic acid (AMPA) binding in human hippocampus in a quantitative autoradiographic study. With dissociation constants (KD) of [3H]AMPA binding and inhibition concentrations

The interactions of ascorbic acid (AA) and reduced glutathione (GSH) in the oxidations of the catecholaminergic neurotoxins 6-hydroxydopa (TOPA) and 6-hydroxydopamine (6-OHDA) were investigated by both high performance liquid chromatography with electrochemical detection (HPLC-ED) and spectrometric methods. These comparative studies

The copper amine oxidases carry out two copper-dependent processes: production of their own redox-active cofactor (2,4,5-trihydroxyphenylalanine quinone, TPQ) and the subsequent oxidative deamination of substrate amines. Because the same active site pocket must facilitate both reactions, individual active site residues

The reaction of NO-derivatized polyamines called "NONOates" with an amine oxidase from lentil seedlings was studied. 3,3-Bis(aminoethyl)-1-hydroxy-2-oxo-1-triazene (DETA-NONOate) and 3,3'-(hydroxynitrosohydrazino)bis-1-propanamine (DPTA-NONOate) were found to be irreversible inactivators of the lentil enzyme. The spectrum of the protein was strongly affected in
