glutathione s-transferases (gsts) are widespread in fasciola. hepatica parasite and sheep liver tissue. study of gsts inhibition assays in f. hepatica and sheep liver tissue are a priority of chemotherapeutic targets in parasitic liver diseases including human fascioliasis in iran. in this research, the whole extract of f. hepatica and sheep liver tissues were purified and eluted for sodium dod...

paracetamol (acetaminophen, pcm) is a widely used over-the-counter analgesic and antipyretic drug. intake of a large dose of pcm may result in severe hepatic necrosis. oxidative stress is mediated by oxidative capacities of the pcm metabolite (n-acetyl-para-benzo quinoneimine, napqi), which covalently binds to proteins and other macromolecules to cause cellular damage. at low doses, napqi is co...

Human erythrocytes were incubated with 3H-glycine to label the glutathione pool. These cells were then used to determine the rate of oxidized glutathione (GSSG) transport out of erythrocytes. For 6 normal individuals, the mean transport rate was 6.7 nmole GSSG/hr/ml red cells. This transport rate would suggest a half-life of 4.7 days for the erythrocytic glutathione, which is in close agreemwnt...

We report a new fluorogenic substrate for glutathione S-transferase (GST), 3,4-DNADCF, enabling the assay with a low level of nonenzymatic background reaction. Inhibitors against Noppera-bo/GSTe14 from Drosophila melanogaster were identified by high throughput screening using 3,4-DNADCF, demonstrating the utility of this substrate.

introduction: the fate of xenobiotics that is present, increasing day by day. the increasing fates altered or inhibit the metabolic activities like detoxification and biotransformation. methods: the present study highlights this slow biotransformation and detoxification on the basis of specific enzymes which have a say in assessment of mercuric chloride toxicity and modulation by panax ginseng ...

We report a novel class of glutathione S-transferase (GST) from the model cyanobacterium Synechocystis PCC 6803 (sll1545) which catalyzes the detoxification of the water pollutant dichloroacetate and also shows strong glutathione-dependent peroxidase activity representing the classical activities of zeta and theta/alpha class respectively. Interestingly, sll1545 has very low sequence and struct...
