Acetochlor [2-chloro-N-(ethoxymethyl)-N-(2-ethyl-6-methylphenyl)-acetamide] is a widely applied herbicide with potential carcinogenic properties. N-Deethoxymethylation is the key step in acetochlor biodegradation. N-Deethoxymethylase is a multicomponent enzyme that catalyzes the conversion of acetochlor to 2'-methyl-6'-ethyl-2-chloroacetanilide (CMEPA). Fast detection of CMEPA by a two-enzyme (...

PURPOSE To study changes in the spontaneous diameter of small retinal arterioles and bradykinin (BK)-induced vasodilation during inhibition of the synthesis of nitric oxide (NO), prostaglandins (PGs), and cytochrome P450 2C8/9-dependent endothelial-derived hyperpolarizing factor (EDHF). METHODS Forty-eight isolated porcine arterioles with a diameter of approximately 70 microm were mounted in ...

To facilitate access to electronic resources for all researchers working in the field of P450 proteins and P450-containing systems, a WorldWide Web server has been established called The Directory of P450-containing Systems at < http://www.icgeb.trieste.it/p450/ >. Currently it contains the most up-to-date list of sequences of both the P450 superfamily and proteins mediating electron transfer t...

In search of new active molecules, a small focused library 1,2,3-triazoles derived from naphthols were efficiently prepared via the click chemistry approach. The synthesized triazole derivatives evaluated for their antifungal, antioxidant and antitubercular activities. Furthermore, to rationalize observed biological activity data, molecular docking study has also been carried out against site c...

in this research, we investigated the cytotoxic mechanisms of one of the widely used pharmaceuticals that are regularly associated with the adverse effects on the liver, sometimes leading to acute liver failure, diclofenac. diclofenac liver cytotoxicity was associated with reactive oxygen species (ros) formation and lipid peroxidation which were inhibited by antioxidants and ros scavengers, fer...

The resistance of mosquitoes to chemical insecticides is threatening vector control programmes worldwide. Cytochrome P450 monooxygenases (CYPs) are known to play a major role in insecticide resistance, allowing resistant insects to metabolize insecticides at a higher rate. Among them, members of the mosquito CYP6Z subfamily, like Aedes aegypti CYP6Z8 and its Anopheles gambiae orthologue CYP6Z2,...
