Advances in molecular biology describing important enzyme systems involved in drug conjugation and deconjugation reactions and recent work indicating the importance of drug and xenobiotic conjugates as transport forms of biologically active compounds are reviewed comprehensively. Part One describes molecular events associated with the expression and regulation of transferases and hydrolases involved in Phase II drug conjugation and deconjugation. Part Two deals with the regulation of Phase II conjugation, and Part Three reviews critically the importance of drug conjugates in pharmacology and toxicology. This volume is an up-to-date source of information on this topic and will be of broad interest to pharmacologists and toxicologists.

A compilation of researchers' experience in the areas of bioanalysis, pharmacokinetics, and drug metabolism, to present an up-to-date and comprehensive treatise on the application of these and related technologies in drug discovery, development, and clinical use. Contents cover descriptions of analytical methods, in vitro metabolism technology and membrane transport, reappraisal of classical pharmacokinetic problems, and the time course of drug action. The book concludes with a description of PET and imaging methods in pharmacokinetics and an appendix containing a critical appraisal of computer methods and pharmacokinetic software available for PCs.
