Liver microsomal epoxide hydrase. [PDF]
1. The substrate specificity of membrane-bound and purified epoxide hydrase from rat liver microsomes has been studied. Both enzyme preparations catalyzed the hydration of a variety of alkene oxidase as well as arene oxides of several polycyclic aromatic hydrocarbons. 2. Unlike the membrane-bound enzyme, the rate of hydration for most of the substrates

Studies on the hyperplasia ('regeneration') of the rat liver following partial hepatectomy. Changes in lipid peroxidation and general biochemical aspects [PDF]
Using the experimental model of partial hepatectomy in the rat, we have examined the relationship between cell division and lipid peroxidation activity. In rats entrained to a regime of 12 h light/12 h dark and with a fixed 8 h feeding period in the dark

Metabolism and Metabolic Inhibition of Xanthotoxol in Human Liver Microsomes [PDF]
Cytochrome p450 (CYP450) enzymes are predominantly involved in Phase I metabolism of xenobiotics. In this study, the CYP450 isoforms involved in xanthotoxol metabolism were identified using recombinant CYP450s.

Species Differences in Stereoselective Pharmacokinetics of HSG4112, A New Anti-Obesity Agent
HSG4112, a racemic drug, is a new anti-obesity agent. In this study, the stereoselective pharmacokinetics of HSG4112 were investigated in rats and dogs, and the underlying mechanism was investigated. The plasma concentrations of HSG4112(S) and HSG4112(R)

In Vitro Metabolism of Donepezil in Liver Microsomes Using Non-Targeted Metabolomics
Donepezil is a reversible acetylcholinesterase inhibitor that is currently the most commonly prescribed drug for the treatment of Alzheimer’s disease. In general, donepezil is known as a safe and well-tolerated drug, and it was not associated with liver ...

Characterization of porcine hepatic and intestinal drug metabolizing CYP450 : comparison with human orthologues from a quantitative, activity and selectivity perspective [PDF]
Over the past two decades, the pig has gained attention as a potential model for human drug metabolism. Cytochrome P450 enzymes (CYP450), a superfamily of biotransformation enzymes, are pivotal in drug metabolism.

Characterization of the human omega-oxidation pathway for omega-hydroxy-very-long-chain fatty acids [PDF]
Very-long-chain fatty acids (VLCFAs) have long been known to be degraded exclusively in peroxisomes via beta-oxidation. A defect in peroxisomal beta-oxidation results in elevated levels of VLCFAs and is associated with the most frequent inherited ...
