Acridinyl methyl esters as photoactive precursors in the release of neurotransmitter amino acids.
An investigation of the use of an azaheterocycle, acridine, as an alternative photochemically removable protecting group for the carboxylic function of neurotransmitter amino acids was carried out. 9-Bromomethylacridine was used in the reaction with glycine, alanine, glutamic acid, β-alanine and γ-aminobutyric acid, to obtain model ester derivatives, which were irradiated at different wavelengt...
متن کاملChanges in neurotransmitter levels associated with the deficiency of some essential amino acids in the diet.
The contents of dopamine (DA) and serotonin (5-HT) and their metabolites were measured in rat substantia nigra and corpus striatum following dietary changes, including restriction of protein content (low-protein diet; LPD) and the contents of several large neutral amino acids (isoleucine, leucine, methionine, phenylalanine, tryptophan and valine) for 25 d. The LPD produced an increase in the co...
متن کاملG-protein-coupled receptors for neurotransmitter amino acids: C-terminal tails, crowded signalosomes.
G-protein-coupled receptors (GPCRs) represent a superfamily of highly diverse integral membrane proteins that transduce external signals to different subcellular compartments, including nuclei, via trimeric G-proteins. By differential activation of diffusible G(alpha) and membrane-bound G(beta)gamma subunits, GPCRs might act on both cytoplasmic/intracellular and plasma-membrane-bound effector s...
متن کاملPhotoinduced DNA cleavage by formation of ROS from oxygen with a neurotransmitter and aromatic amino acids.
UV-B photoirradiation of a neurotransmitter (serotonin) and aromatic amino acids (tryptophan and tyrosine) with oxygen results in DNA cleavage by generation of reactive oxygen species (ROS) as demonstrated by agarose gel electrophoresis with pBR 322 DNA, ESR and laser flash photolysis measurements.
متن کاملNigella sativa L. Seed Extract Modulates the Neurotransmitter Amino Acids Release in Cultured Neurons In Vitro
Nigella sativa L. (NS) has been used for medicinal purposes since ancient times. This study aimed to investigate the cytotoxicity of NS dry methanolic extract on cultured cortical neurons and its influence on neurotransmitter release, as well as the presence of excitatory (glutamate and aspartate) and inhibitory amino acids (gamma-aminobutyric acid-GABA-and glycine) in NS extract. Cultured rat ...
