Mechanism of induction of cytochrome P-450 by phenobarbital.
Treatment of rats with phenobarbital (PB) leads to a substantial increase in the hepatic levels of translatable polysomal poly(A) + cytochrome P-450 mRNA. An enriched fraction of P-450 mRNA was obtained by agarose gel electrophoresis and used to prepare a cDNA probe by differential hybridization to total mRNA from control and PB-treated rats. The majority of the sequences within the probe hybri...
متن کاملEpoxidation of unsaturated fatty acids by a soluble cytochrome P-450-dependent system from Bacillus megaterium.
In previous publications from this laboratory we have described a soluble, partially purified cytochrome P-450-dependent monooxygenase complex that, in the presence of NADPH and O2, catalyzes the monohydroxylation of long chain fatty acids, alcohols, and amides at the omega -1, omega -2, and omega -3 positions. We have now found that this preparation catalyzes the epoxidation as well as the hyd...
متن کاملThe rate-determining step in the epoxidation of alkenes by the cytochrome P-450 model manganese(III) porphyrin/hypochlorite
Using low-temperature trapping experiments with 1 ,l-diphenyl-2-picrylhydrazine moni tored by UV/Vis spectroscopy, it is shown that the rate-determining step in the epoxidation of alkenes by hypochlorite, catalysed by manganese(III) porphyrins, involves the formation of the active oxo-manganese species [(P)MnO]+.
متن کاملa study on insurer solvency by panel data model: the case of iranian insurance market
the aim of this thesis is an approach for assessing insurer’s solvency for iranian insurance companies. we use of economic data with both time series and cross-sectional variation, thus by using the panel data model will survey the insurer solvency.
Heterogenization of Alkene Epoxidation Catalysts
Este trabalho descreve nosso esforço em heterogeneizar catalisadores para epoxidação. Tanto o molibdênio ancorado quanto o engaiolado pelo método de sol-gel mostraram grande seletividade, mas possuem suas atividades fortemente reduzidas. Por outro lado, silicatos de molibdênio foram muito ativos e estáveis até a formação de diols na mistura reacional. Catalisadores heterogeneizados de rênio for...
