Use of Nano-Electrospray for Metabolite Identification and QuantitativeAbsorption, Distribution, Metabolism and Excretion Studies
Determination of the pharmacokinetics and metabolite identification have been an integral part of drug discov-ery and development to ensure that drugs have appropriate absorption, distribution, metabolism and excretion properties.Liquid chromatography interfaced with a mass spectrometer has greatly facilitated these studies. Nano-electrospray hasdistinct sensitivity advantages and the increased amount of time available to perform mass spectrometric experiments fa-cilitates structural characterization of metabolites. The recently developed silicon chip-based nano-electrospray devicesare more practical than pulled capillaries. The use of these devices for the determination of pharmacokinetics and metabo-lite identification will be described and particular attention will be paid to the distinct advantages and disadvantages thesedevices offer.

- Current Drug Metabolism aims to cover all the latest and outstanding developments in drug metabolism and disposition. The journal serves as an international forum for the publication of timely reviews in drug metabolism. Current Drug Metabolism is an essential journal for academic, clinical, government and pharmaceutical scientists who wish to be kept informed and up-to-date with the latest and most important developments. 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 and adducts. - Editorial Board
