The microsomal O-deethylation of a novel coumarin analog, 7-ethoxy-4-trifluoromethylcoumarin (EFC), to a fluorescent product was characterized. Results indicate that this analog provides a rapid, convenient and highly sensitive means to assay cytochrome P-450-mediated metabolism. Like microsomal 7-ethoxycoumarin (7-EC) O-deethylation, EFC

The aim was to characterize mouse gender and strain differences in the metabolism of commonly used human cytochrome (CYP) P450 probe substrates. Thirteen human CYP probe substrates (phenacetin, coumarin, 7-ethoxy-4-trifluoromethyl coumarin, amiodarone, paclitaxel, diclofenac, S-mephenytoin, bufuralol, dextromethorphan, chlorzoxazone, p-nitrophenol, testosterone

The addition of peroxynitrite to purified cytochrome P450 2B1 resulted in a concentration-dependent loss of the NADPH- and reductase-supported or tert-butylhydroperoxide-supported 7-ethoxy-4-(trifluoromethyl)coumarin O-deethylation activity of P450 2B1 with IC50 values of 39 and 210 microM, respectively. After incubation of P450

Tetranychus urticae Koch has recently developed resistance to chlorfenapyr in Australia and Japan, but no attempt has yet been made to describe the biochemical mechanisms involved in chlorfenapyr resistance. In this study a laboratory-selected chlorfenapyr-resistant strain was investigated. Resistance to

Improvement of CYP2B6 expression was examined by co-expression with molecular chaperones GroES/EL. Although a CO-reduced difference spectrum was not detected in Escherichia coli transformed only by the CYP2B6-expressing vector, co-expression of GroES/EL resulted in high-level expression which reached over 2000
