It is well known that Arginine-Glycine-Aspartic acid (RGD) and Asparagine-Glycine-Arginine (NGR) peptides preferentially bind to integrin receptors and aminopeptidase Nrespectively and these two receptors play important roles in angiogenesis. Therefore ketoprofenas a non-selective cox Inhibitor was conjugated with linear RGD and NGR to take advantageof targeting capability of these two motifs a...

Multiple lines of evidence indicate that hypofunction of glutamatergic neurotransmission via N-methyl-D-aspartate (NMDA) receptors might be implicated in the pathophysiology of schizophrenia, suggesting that increasing NMDA receptor function via pharmacological manipulation could provide a new strategy for the management of schizophrenia. Currently, the glycine modulatory sites on NMDA receptor...

In Xenopus oocytes injected with rat brain mRNA, as in neurons, glycine greatly potentiated responses of the N-methyl-D-aspartate (NMDA) type of excitatory amino acid receptor. Injected oocytes generated a partially desensitizing inward current in response to NMDA with 30 nM added glycine. As the added glycine concentration was increased from 30 nM to 1 microM, the NMDA response was increased a...

Fasting and postprandial plasma concentrations of glycine and taurine conjugates of cholic, chenodeoxycholic, and deoxycholic acid were measured by a high pressure liquid chromatography-enzymatic assay in nine healthy subjects. The mean value of each bile acid concentration increased significantly (2.4-4.7 times) in the postprandial period. The total glycine taurine ratio of 2.5 in the fasting ...

The GABA(A) antagonist SR-95531 (gabazine) is known to block glycine receptors, albeit with low affinity. We have studied the effect of SR-95531 on rat recombinant alpha1beta glycine receptors expressed in human embryonic kidney (HEK293) cells by recording macroscopic currents elicited by rapid glycine application to outside-out patches. SR-95531 has a fast unbinding rate (k(offSR), about 3000 ...

In the course of glycine conjugation, benzoic acid is successively converted into benzoyl-CoA and benzoylglycine by mitochondrial enzymes (i.e. benzoyl-CoA synthetase and benzoyl-CoA/glycine N-acyltransferase, respectively), utilizing ATP, CoA, and glycine. Large doses of benzoate deplete CoA from the liver, suggesting that the supply of CoA may limit the capacity for glycine conjugation. Becau...

Objective: Polyphenol oxidase or PPO (EC 1.14.18.1) is considered the enzyme responsible for quality deterioration and browning in different fruits during postharvest period. The objective of this study was to evaluate the antibrowning (inhibition of polyphenol oxidase activity) effect of Cysteine, Ascorbic acid, citric acid, kojic acid and glycine at two different pH (6 and 7) in  hawthorn. Me...

Many anti-epileptic drugs (AEDs) that mainly target ion channels or post-synaptic receptors are in clinical use, but a proportion of patients are resistant to these traditional AEDs and experience repeated severe break-out seizures. Given its involvement in the etiology of epilepsy, the neurotransmitter glycine may serve as a novel target for epilepsy treatment. Increasing evidence suggests tha...
