    Author: Chen J, Korfmacher WA, Hsieh Y.
    Journal: J Chromatogr B Analyt Technol Biomed Life Sci; 2005 Jun 05; 820(1):1-8. PubMed ID: 15866486.
    Abstract:
    The characterization of the drug metabolism and pharmacokinetic (DMPK) profiles of stereoisomers is a fundamental aspect of the drug discovery and development processes. Therefore, chiral drug bioassays are very important to pharmaceutical and biomedical researchers. The recent developments in chiral liquid chromatography coupled to atmospheric pressure ionization tandem mass spectrometry (LC-API-MS/MS) for the analysis of pharmaceuticals are reviewed. Various ionization techniques including electrospray ionization (ESI), atmospheric pressure chemical ionization (APCI) and atmospheric photoionization (APPI) interfaced with chiral liquid chromatographic methods are described in terms of their ionization efficiencies, matrix effects and limitations. Examples were selected to demonstrate the applicability of these methods for enantioselective bioanalysis.
