The aim of the present work was to investigate a new mechanism likely contributing to the toxic action of acetaminophen, especially to explore the possible inhibition of glutathione reductase through an acetaminophen-glutathione conjugate (APAP-SG). APAP-SG conjugate was synthesized by organic synthesis and purified by column chromatography. The inhibitory effect of the conjugate on two types o...
beta-N-oxalyl-amino-L-alanine, (L-BOAA), an excitatory amino acid, acts as an agonist of the AMPA subtype of glutamate receptors. It inhibits mitochondrial complex I in motor cortex and lumbosacral cord of male mice through oxidation of critical thiol groups, and glutaredoxin, a thiol disulfide oxido-reductase, helps maintain integrity of complex I. Since incidence of neurolathyrism is less com...
UNLABELLED Multiple sclerosis (MS) is a chronic, inflammatory and autoimmune disease of the central nervous system. Dysregulation of glutathione homeostasis and alterations in glutathione-dependent enzyme activities are implicated in the induction and progression of MS. Evidence suggests that Omega-3 polyunsaturated fatty acids (PUFAs) have anti-inflammatory, antioxidant and neuroprotective eff...
Investigation of prolidase, adenosine deaminase, glutathione S-transferase and glutathione reductase
A Selective Glutathione Probe based on AIE Fluorogen and its Application in Enzymatic Activity Assay
In this work, we design and synthesize a malonitrile-functionalized TPE derivative (TPE-DCV), which can react with thiol group through thiol-ene click reaction, leading to the fluorescence change of the system. Combined with the unique AIE property, TPE-DCV can selectively detect glutathione (GSH) but not cysteine or homocysteine. As the cleavage of GSSG with the aid of glutathione reductase pr...
The purpose of this study is to determine the relationship between enzymatic antioxidants such as glutathione reductase and s-transferase prolidase adenosine deaminase in patients diagnosed with pancreatic cancer. Prolidase, deaminase, activities were determined spectrophotometrically blood sera collected from healthy control subjects included study. In cancer, mean value enzymes decreased, whi...

Extensive amino acid sequence homology has been found between nine tryptic peptides of pig heart lipoamide dehydrogenase (NADH:lipoamide oxidoreductase, EC 1.6.4.3] and the sequence of human erythrocyte glutathione reductase [NAD(P)H:glutathione oxidoreductase, EC 1.6.4.2]. The average homology is 40%. Six lipoamide dehydrogenase peptides are homologous with segments of the two parts of the FAD...
Physiological features were examined of a 20-year-old Vitis vinifera ‘Italia’ table grape vineyard cropped in Apulia, Italy. Healthy vines with no foliar symptoms and any indications wood or berry alterations, natural infections by Phaeoacremonium minimum (syn. P. aleophilum) Phaeomoniella chlamydospora showing brown streaking symptoms, naturally infected minimum, Fomitiporia mediterranea white...
Quercetin and galangin can change the activity of glutathione reductase. Quercetin (a catechol structure in the B-ring) and galangin (any hydroxyl group in the B-ring) have different biological activities but, both possess high antioxidant abilities. Quercetin during the antioxidative action, is converted into an oxidized products (o-semiquinone and o-quinone), and subsequently glutathionyl add...
