This book covers strategies to improve cell permeability, intestinal permeability, and metabolic stability, which are the typical liabilities associated with cyclic peptides, to enhance protein-protein recognition, and to build upon nature's cyclic peptides and macrocycles. Chapters also cover key peptide screening and display strategies, as well as important synthetic approaches towards cyclic and helical peptides. Cyclic peptides have become of significant importance as chemical tools in biology and drug discovery, since this class of chemicals has become a credible alternative source of new drug leads on par with traditional small molecules. As a part of the iMethods in Molecular Biologyi series, this collection includes the kind of detail and implementation advice to aid researchers in the field. brAuthoritative and cutting-edge, iCyclic Peptide Designi serves as a critical resource and go-to reference for researchers within the pharmaceutical industry, as well as scientists and st
