[DNLM: QU 68P4256 1998] QD431.P38 1998 615'.19---dc21 DNLM/DLC for Library of Congress 98-26947 CIP Preface Many physiologically important receptors and enzymes are regulated by their endogenous ligands and inhibitors. Nature chose to utilize these pep- tides as chemical switches since they can be efficiently synthesized and de- graded in cells, thus providing an immediate response to a fast changing environment. Such properties, so critical in cell survival, make peptides less than ideal drug candidates. Other frequently desired properties in drug mol- ecules include oral bioavailability, the ability to cross membranes, including the blood-brain barrier, and sufficient stability for administration 1-2 times a day. In spite of these obstacles, some natural peptides and proteins are indis- putably successful medicines and have become drugs of choice. Further ad- vances in peptide-based pharmaceuticals are critically dependent on both new delivery methods and new chemical approaches to the conversion of these molecules to druglike entities. In addition, peptides are also the natural start- ing points for optimization of their pharamacological and chemical proper- ties, which may lead to superior drugs. Peptidomimetics Protocols deals with both aspects of peptide pharmaceuticals, through the tools of modern syn- thetic and medicinal chemistry. The last decade has witnessed a steady stream of new synthetic approaches to peptide mimetics, compounds that replace physi- ologically vulnerable peptide functionalities with chemical modules of in- creased stability and cellular penetration. The chapters have been written by both academic and industrial chemists, and focus on the practical synthetic preparation of peptide mimetics. The first set of chapters focuses on selected (asymmetric) syntheses of amino acids. Proline derivatives (Chapter l), cyclopropy! (Chapters 2 and 3), topographically constrained ~-alkyl derivatives, and cyclic amino acids with constrained rotation around the Z l and 2Z bonds (Chapters 4 and 5) are supple- mented by methods leading to allyl (Chapters 1 and 3) and vinyl (Chapter 6) amino acids amenable for further derivatization. The next 01 chapters describe the use of a variety of linear and heterocy- clic scaffolds in place of the peptide backbone, which is often associated with poor peptide pharmacokinetics. Cyclic scaffold-based turn structures are cov- vi Preface ered by Chapters ,7 ,8 and 12-16, whereas linear scaffolds (potentially uti- lized by protease inhibitors) are described in Chapters 9-11. Chapter 21 pro- vides chemistry leading to functionalized benzodiazepines, a scaffold found in many successful drugs, and Chapter 31 focuses on carbohydrate scaffolds as peptide mimetics. The chemistry of aromatic ethers as conformational con- straints is explored in Chapter .41 The chemistry in Chapters 17-21 replaces peptides' "Achilles heel" peptide bonds~with pentacyclic rings (Chapters 71 and 19), olefins and fluoroolefins (Chapters 12 and ,81 respectively), ~[CH O]ether isoteres (Chap- ter 20), and ketomethylenes (Chapter 22). Novel chemistry (Chapters 23-25) allows the transient protection of charged peptides as neutral prodrugs. Following their uptake by the brain, peptides are liberated by esterases owing to the chemical instability of the resulting intermediates. The final chapters cover those transition-state mimics and reactive "war- heads" applicable in enzyme inhibitors. Chapters 26, 28, and 29 deliver syn- thetic methodologies to a variety of potential aspartyl protease amino acid- and dipeptide-based precursors, whereas Chapter 27 focuses on oxiranes as cysteine- and serine-protease inhibitors. It is my hope that Peptidomimetics Protocols will provide both synthetic procedures for key peptide mimetics and stimulate new ideas. Many of the chemistries described are amenable to combinatorial techniques. The work on this volume took place in Research Triangle Park, NC and Verona, Italy, during my stay there in 1997-1998. I am truly grateful to Gor- don Hodgson and Tino Rossi, respectively, for their encouragement. Professor John Walker is to be acknowledged for his bright selection of Peptidomimetics Protocols as a volume in the Methods ni Molecular Medicine series, as well as his valuable comments and advice. This book would not be- come a reality without the hardworking and talented staff of Humana Press" Thomas L. Lanigan, Fran Lipton, James Geronimo, and many others. Investigators at more than 27 different laboratories from six countries contributed chapters to this book. I am truly indebted to all of them for their professionalism, their adherence to schedules, their enthusiasm, and, most of all, their high-quality contributions. Finally, this editor would like to dedicate his work to Maria, Konstantin, and Christian. Their support and understanding during countless lonely week- ends and evenings contributed enormously to this volume. Wieslaw M.
