Biotransformation and Metabolite Elucidation of Xenobiotics: Characterization and Identification

An Up–To–Date Guide on the Exciting Possibilities of Metabolite Identification in Drug Discovery
Over the years, metabolite identification and characterization have progressed to the point where they now play a major role in drug discovery and development. In particular, the metabolite elucidation of xenobiotics has been instrumental in increasing the success rate of selected drug candidates that hold the most promise for being safe and effective.
To explore the analytical possibilities present in this field, this book provides in–depth coverage on designing, developing, and advancing metabolite characterization for drug research. It discusses topics ranging from how and when to perform metabolite identification and characterization to perspectives on regulatory requirements. Biotransformation and Metabolite Elucidation of Xenobiotics also:
Excellent primer and updated chapter on human biotransformation by Dr. Parkinson
Supplies up–to–date details on the tools and techniques needed to perform metabolite identification
Presents modern approaches and strategies to deal with metabolite characterization, using techniques such as LC–MS , H–D exchange, stable isotopes, and LC–MS–NMR
Provides case studies to help improve the decision–making process in the structural modification of drug candidates—enhancing metabolic stability, improving PK properties, and reducing toxicity
Includes FDA guidelines such as "Safety Testing of Drug Metabolites"
Giving direction and focus to improving drug discovery techniques, Biotransformation and Metabolite Elucidation of Xenobiotics is a pioneering guide rich in content that displays the verve of experts passionate about their work. It carefully and systemically approaches educating researchers and students to instill them with a better understanding on how to apply the principles of metabolite identificat ion to create drugs that are safer, more targeted, and able to perform to the highest standards.

Nota biograficzna:
ALA F. NASSAR, PHD, has worked in the pharmaceutical industry for more than ten years. For over five years, Dr. Nassar oversaw the drug metabolism and bioanalytical department at Vion Pharmaceuticals, working in these key areas of drug discovery and development. One principal area of his research involved understanding how structure modification can improve the ADME profile for new chemical entities as they advance toward cl inical candidacy. He identified and subsequently patented pharmacologically active metabolites of Nexavar® (sorafenib), and recently identified the pharmacologically active metabolite of OnriginTM (laromustine), and is in the process of seeking a patent on this discovery. Dr. Nassar has more than fifty publications in journal articles and book chapters; and has taught and coordinated several courses on bioanalytical chemistry, LC–MS, and drug metabolism to share his experience with other scientists in the field. Currently, he is the Director of the Mass Spectrometry Facility and Research Assistant Professor at Brandeis University.
