OXIDATIVE DRUG METABOLISM IN HUMAN LIVER MICROSOMES

The Journal of Pharmacology and Experimental Therapeutics, 1971
Isolated human liver microsomes were studied with respect to reduced nicotinamide adenine dinucleotide phosphate (NADPH)-cytochrome c reductase, NADPH-cytochrome P-450 reductase, aminopynine demethylase activity and the content of cytochrome P-450 ...

The lipid composition of human liver microsomes

Lipids, 1982
AbstractThe lipid composition of human liver microsomes isolated from liver biopsy samples obtained at abdominal surgery has been determined. Human liver microsomal phospholipid is composed of 49% phosphatidylcholine, 31% phosphatidylethanolamine, 14% phosphatidylserine+phosphatidylinositol and 6% sphingomyelin, very similar to the phospholipid ...

Biotransformation of (−)-Verbenone by Human Liver Microsomes

Bioscience, Biotechnology, and Biochemistry, 2002
The biotransformation of (-)-verbenone was investigated with human liver microsomes by using GC-MS. Regioselective biotransformation was observed when (-)-verbenone was incubated with the liver microsomes. (-)-10-Hydroxyverbenone was formed from (-)-verbenone of kinetic analysis showed that the Km and Vmax values for the hydroxylation of (-)-verbenone ...

Phenobarbital N-glucosylation by human liver microsomes

European Journal of Drug Metabolism and Pharmacokinetics, 2004
Glucosylation of xenobiotics in mammals has been observed for a limited number of drugs. Generally, these glucoside conjugates are detected as urinary excretion products with limited information on their formation. An in vitro assay is described for measuring the formation of the phenobarbital N-glucoside diasteriomers ((5R)-PBG, (5S)-PBG) using human ...

Cytochrome P450 inhibitors. Evaluation of specificities in the in vitrometabolism of therapeutic agents by human liver microsomes.

Drug Metabolism And Disposition, 1995
Identifying selective inhibitors of cytochrome P450 isoforms is a useful tool in defining the role of individual cytochrome P450s in the metabolism process.

Microsomal Esterification of Retinol in Human Liver

Acta Medica Scandinavica, 1984
Abstract Recent work has shown that esterification of retinol in microsomes from rat liver, mammary gland and small intestine and from human small intestine is catalyzed by an acyl CoA: retinol acyl transferase (ARAT). The current study demonstrates ARAT activity in human liver microsomes.
