Summary

This book provides a wealth of information on how small structural modifications affect the pharmacokinetic properties of a compound, and thus gives rich, fact-based inspiration for the efficient development of new drugs. It is a valuable and compact reference guide for both medicinal chemists and graduate students in the pharmaceutical sciences.

Author Biography

Florencio Zaragoza D?rwald studied chemistry at the Georg-August University in G?ttingen, Germany, and Universit? LouisPasteur, Strasbourg, France, where he obtained his Ph.D. in 1990 on the synthesis of natural products under the guidance of M. Franck-Neumann and M. Miesch. He spent one postdoctoral year in both the groups of A. Pfaltz (University of Basel) and A. P. Marchand (University of North Texas), and then worked on the synthesis of unnatural amino acids at the Technical University of Dresden. From 1994 to 2007 he had a position as
a medicinal chemist at Novo Nordisk A/S, Denmark. Currently, he is employed as organic chemist at Lonza AG in Visp, Switzerland.
