RESORUFIN ETHYL ETHER Chemical Properties,Usage,Production
Chemical Properties
Red Solid
Uses
A fluorimetric substrate for cytochrome P450 IAI. Inhibits vasorelaxant responses to acetylcholine
Uses
Dealkylase substrate for the microfluorimetric analysis of microsomal cytochrome P-450.
Uses
Resorufin ethyl ether is suitable for the study of dealkylating activity of cytochrome P450 isozymes 1A1 and 1A2, where arylalkyl and alkyl isothiocyanates, and their glutathione, cysteine, and A′-acetylcysteine conjugates are used as inhibitors. It is suitable to study the ethoxyresorufin-O-deethylase (EROD) activity of cytochrome P450 activity (CYP1A1).
Definition
ChEBI: 7-ethoxyresorufin is a phenoxazine.
General Description
Resorufin ethers are used as markers or substrates for different cytochrome P (CYP) isoforms. Resorufin ethyl ether is the preferred resorufin ether to be metabolized by microsomes of 3-methylcholanthrene treated animals.
Biological Activity
cytochrome p450, family 1, subfamily a, polypeptide 1 is a protein that is encoded by human cyp1a1 gene. the protein is a member of the cytochrome p450 superfamily of enzymes. cyp1a1 is involved in phase i xenobiotic and drug metabolism. cyp1a1 is inhibited by fluoroquinolones and macrolides and induced by aromatic hydrocarbons. 7-ethoxyresorufin is a specific subtrate of cyp1a.
in vitro
7-ethoxyresorufin (2-10 microm), a substrate for cytochrome p450, which binds to the heme moiety of the enzyme, reduced responses to acetylcholine concentration-dependently but not the other agonists indicating an effect on nitric oxide synthesis although neither affected the conversion of l-arginine to l-citrulline [1].
in vivo
activities of cyp1a (7-ethoxyresorufin) in the liver was determined for comparative purposes. in mice, lps depressed cyp2a5 at low doses but not at doses that increased pro-inflammatory cytokines and no serum levels, and depressed cyp1a activity. blockade of proinflammatory cytokines extended down-regulation of cyp2a5 while not affecting lps-induced depression of cyp1a [2].
storage
Store at -20°C
