Abstract:

A fast and sensitive method was developed for the assessment of CYP induction in human hepatocytes cultured in 96-well plates. The effects on CYP1A2, CYP2A6, CYP2B6, CYP2C9, CYP2C19, and CYP3A4 were examined by means of mass spectrometry and the well-known cocktail strategy. The performance of the method was tested by using prototypic inducers such as methylcolanthrene, phenobarbital and rifampicin. The method was shown to be robust and predictable for the in vitro induction potential studies of drugs.

Drug Metabolism Letters publishes short papers on major advances in all areas of drug metabolism and disposition. The emphasis will be on publishing quality papers very rapidly. Letters will be processed rapidly by taking full advantage of the Internet technology for both the submission and review of manuscripts. The journal covers the following areas:

In vitro systems including CYP-450; enzyme induction and inhibition; drug-drug interactions and enzyme kinetics; pharmacokinetics, toxicokinetics, species scaling and extrapolations; P-glycoprotein and transport carriers; target organ toxicity and interindividual variability; drug metabolism and disposition studies; extrahepatic metabolism; phase I and phase II metabolism; recent developments for the identification of drug metabolites, reactive intermediate and glutathione conjugates.
