Gamma hydroxybutyric acid (GHB), an endogenous constituent of the mammalian brain, acts as i) a neurotransmitter or neuromodulator, ii) a medicine used for the treatment of narcolepsy and alcoholism, and iii) a drug illicitly used for its psychotropic effects. GHB is thought to act as a specific GHB receptor agonist as well as a weak gamma-aminobutyric

Abstract— The effects of 121 mm‐K+, 10 mm‐glutamate, 5 mm‐GABA, 1 mm‐glycine, 0.1 mm‐NE, and 1–10 μmACh on cyclic GMP levels in tissue slices prepared from cerebral cortex and cerebellum of mouse, rabbit, guinea‐pig, cat, and rat were studied. Basal levels of cyclic GMP in the cerebella of mice, guinea‐pigs and cats were 4–15 and 70 pmol/mg prot in rat,

Abstract Recent insight has implicated the formation of β-amyloid fibril formation as a culpable process for the progression of Alzheimer's disease. Amyloid-β (Aβ) is a peptide naturally secreted by neurons in a random coil structure. It has been deduced that a conformational transition from a random coil to a β-pleated sheet is responsible for Aβ's ...

Hepatic tryptophan 2,3-dioxygenase (TDO) is one of the rate-limiting enzymes in tryptophan catabolism and plays an important role in regulating the physiological flux of tryptophan into relevant metabolic pathways. In this study, we determined the effect of the non-steroidal anti-inflammatory agents, tolmetin and sulindac, on rat liver TDO activity and

Discoveries of Neurotransmitter Agents and Modulators of Neuronal Functions
1992At a dinner speech in Atlantic City in 1950, Otto Loewi commented on some facets of his work that had led to the discovery of neurochemical transmission. He mentioned that Sir Walter Fletcher, years after the discovery, reminded him that as far back as 1903 Loewi had pointed out to him the possibility of a neurochemical transmission.

One of the phasic phenomena of REM (rapid eye movement) sleep, the ponto-geniculo-occipital (PGO) waves, are induced in cats by either depleting brain monoamines with the benzoquinolizine derivative Ro 4-1284 or inhibiting the synthesis of 5-hydroxy-tryptamine (5-HT) by p-chlorophenylalanine (PCPA). The effects of the most important psychotropic agents

Since the original discovery of Hokin and Hokin1 that the application of acetyIcholine in the presence of eserine to cerebral cortex slices of guinea pigs greatly stimulated their incorporation of 32pi into certain phospholipids, which were later shown to be chiefly Phla and PhA, several investigators have confirmed this observation in a wide variety ...

AbstractBacterial cells employ diverse mechanisms to perceive and respond to host-associated molecules, coordinate intracellular signal transduction, and engage in interkingdom communications. In this study, we firstly discovered that the adrenergic antagonist dronedarone (DDR) effectively suppresses quorum sensing (QS) and pathogenesis of the ...
