LC-MS/MS in Proteomics by Pedro R. Cutillas,John F. Timms Pdf

With the development of new quantitative strategies and powerful bioinformatics tools to cope with the analysis of the large amounts of data generated in proteomics experiments, liquid chromatography with tandem mass spectrometry (LC-MS/MS) is making possible the analysis of proteins on a global scale, meaning that proteomics can now start competing with cDNA microarrays for the analysis of whole genomes. In LC-MS/MS in Proteomics: Methods and Applications, experts in the field provide protocols and up-to-date reviews of the applications of LC-MS/MS, with a particular focus on MS-based methods of protein and peptide quantification and the analysis of post-translational modifications. Beginning with overviews of the use of LC-M/MS in protein analysis, the book continues with topics such as protocols for the analysis of post-translational modifications, with particular focus on phosphorylation and glycosylation, popular techniques for quantitative proteomics, such as multiple reaction monitoring, metabolic labelling, and chemical tagging, biomarker discovery in biological fluids, as well as novel applications of LC-MS/MS. Written in the highly successful Methods in Molecular BiologyTM series format, chapters include introductions to their respective subjects, lists of necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and notes on troubleshooting and avoiding known pitfalls. Comprehensive and cutting-edge, LC-MS/MS in Proteomics: Methods and Applications presents the techniques and concepts necessary in order to aid proteomic practitioners in the application of LC-MS/MS to essentially any biological problem.

Drug Metabolism, Pharmacokinetics and Bioanalysis by Hye Suk Lee,Kwang-Hyeon Liu Pdf

Drug metabolism/pharmacokinetics and drug interaction studies have been extensively carried out in order to secure the druggability and safety of new chemical entities throughout the development of new drugs. Recently, drug metabolism and transport by phase II drug metabolizing enzymes and drug transporters, respectively, as well as phase I drug metabolizing enzymes, have been studied. A combination of biochemical advances in the function and regulation of drug metabolizing enzymes and automated analytical technologies are revolutionizing drug metabolism research. There are also potential drug–drug interactions with co-administered drugs due to inhibition and/or induction of drug metabolic enzymes and drug transporters. In addition, drug interaction studies have been actively performed to develop substrate cocktails that do not interfere with each other and a simultaneous analytical method of substrate drugs and their metabolites using a tandem mass spectrometer. This Special Issue has the aim of highlighting current progress in drug metabolism/pharmacokinetics, drug interactions, and bioanalysis.

Mass Spectrometry in Drug Metabolism by Frigerio Pdf

When a dose of drug is administered, three main phases of drug action may be distingushed. In the "pharmaceutical" phase the dosage form disintegrates, the active substance dissolves and becomes available for absorption. The second phase ("pharmaco kinetic" phase) includes absorption, distribution, metabolism, and excretion. That fraction of the dose which finally reaches the circulation after absorption will be available for biological action in the third, or "pharmacodynamic" phase when the drug reaches the target tissues and a drug-receptor interaction takes place. The objectives in studies of drug metabolism are: (a) to identify the pathways by which drugs are transformed in the body; (b) to ascertain quantitatively the importance of each pathway and intermediate; (c) to identify and quantify endogenous constituents influenced by the drug or its metabolites which may interfere with common metabolic processes. Since metabolites usually differ from their precursors by only a single chemical group, the resulting metabolic pathways generally consist of a series of closely related compounds. Mass spectrometry is uniquely suited for the analysis of drugs and metabolites for several reasons: only a minimal amount of sample preparation is needed, closely related compounds can be analyzed in a single step, structures can often be deduced directly from the mass spectra without the need for pure reference spectra, and constituents can be quantified with relative ease even when present in fractional nanogram quantity.
