Peptides and proteins are crucial biomolecules in life. The manifold functions they carry out range from molecular recognition and signaling to catalysis and immune response. However, the native systems are limited to a reduced toolbox of chemical functionalities as well as tridimensional structures. Widening these toolboxes could pave the way to engineer peptides and proteins with enhanced properties compared to their native counterparts and/or with structures and functions unprecedented in Nature. Advances in the chemical and biological synthesis of peptides and proteins, in computational tools, in molecular biology and in high-throughput screening methods are making this realm possible.This book aims to give an overview of the last developments in the field of peptide and protein engineering. It comprises a collection of chapters that span from the production of simple non-proteinogenic building blocks and peptidic scaffolds of different sizes and structures to more complex systems including peptide-based nanomaterials, enzymes and artificial metalloenzymes. Different strategies are described where chemical and biological tools have been developed and combined to attain the desired properties and sought functionalities.The diverse systems described in this book highlight the progress in this important field and represent the starting points for the development of functional biomolecules, biomaterials and hybrid systems capable of addressing key societal challenges of our times in relevant areas such health, environment and energy.

This book explains how peptide-based drug design works, what steps are needed to develop a peptide-based therapeutic, and challenges in synthesis as well as regulatory issues. It covers the design concept of peptide therapeutics from fundamental principles using structural biology and computational approaches. The chapters are arranged in a linear fashion. A fresh graduate or a scientist who works on small molecules can use this to follow the design and development of peptide therapeutics to use as understanding the basic concepts. Each chapter is written by experts from academia as well as industry. Rather than covering extensive literature, the book provides concepts of design, synthesis, delivery, as well as regulatory affairs and manufacturing of peptides in a systematic way with examples in each case. The book can be used as a reference for a pharmaceutical or biomedical scientist or graduate student who wants to pursue their career in peptide therapeutics. Some chapterswill be written as a combination of basic principles and protocol so that scientists can adopt these methods to their research work. The examples provided can be used to perform peptide formulation considerations for the designed peptides. The book has nine chapters, and each chapter can be read as an independent unit on a particular concept.

Peptide therapy has become a key strategy in innovative drug development, however, one of the potential barriers for the development of novel peptide drugs in the clinic is their deficiencies in clearly defined chemistry, manufacturing and controls (CMC) strategy from clinical development to commercialization. CMC can often become a rate-limiting step due to lack of knowledge and lack of a formal policy or guidelines on CMC for peptide-based drugs. Regulators use a risk-based approach, reviewing applications on a case-by-case basis.Peptide Therapeutics: Strategy and Tactics for Chemistry, Manufacturing, and Controls covers efficient manufacturing of peptide drug substances, a review of the process for submitting applications to the regulatory authority for drug approval, a holistic approach for quality attributes and quality control from a regulatory perspective, emerging analytical tools for the characterisation of impurities, and the assessment of stability.This book is an essential reference work for students and researchers, in both academia and industry, with an interest in learning about CMC, and facilitating development and manufacture of peptide-based drugs.

A peptidomimetic is a small protein-like chain designed to mimic a peptide with adjusted molecular properties such as enhanced stability or biological activity. It is a very powerful approach for the generation of small-molecule-based drugs as enzyme inhibitors or receptor ligands. Peptidomimetics in Organic and Medicinal Chemistry outlines the concepts and synthetic strategies underlying the building of bioactive compounds of a peptidomimetic nature. Topics covered include the chemistry of unnatural amino acids, peptide- and scaffold-based peptidomimetics, amino acid-side chain isosteres, backbone isosteres, dipeptide isosteres, beta-turn peptidomimetics, proline-mimetics as turn inducers, cyclic scaffolds, amino acid surrogates, and scaffolds for combinatorial chemistry of peptidomimetics. Case studies in the hit-to-lead process, such as the development of integrin ligands and thrombin inhibitors, illustrate the successful application of peptidomimetics in drug discovery.

Macromolecular (specifically peptide-based) drugs could potentially be highly effective medicines. However they have a relatively short duration of action and variable therapeutic index. An example of such a peptide is Glucagon-like Peptide I which could potentially be used as a revolutionary drug for diabetes. This is because it stimulates insulin only when the blood glucose level is high thereby reducing the risk of hypoglycemia (a significant disadvantage of using insulin is that an insulin overdose is the single most potent cause of life-threatening hypoglycemia). However it's short duration of action (half-life of 2 minutes in plasma) precludes its therapeutic use. In this volume, the use of novel therapeutics like GLP1 as an alternative to tradition insulin-based drugs in diabetes is described. Application of Peptide-Based Prodrug Chemistry in Drug Development elucidates the traditional concept of prodrugs as “specialized non-toxic protective groups used in a transient manner to alter or to eliminate certain limiting properties in the parent small molecule” (IUPAC definition). It goes on to provide insight into how prodrugs of peptides (with GLP1 as an example) could be appropriately used to extend the biological half life, broaden the therapeutic index of macromolecules and improve the pharmacodynamics of such drugs. Author explains the logic behind designing peptide prodrugs, synthetic procedures and bioassays to examine the conversion of the prodrug to the drug under therapeutic conditions. The prodrugs described slowly convert to the parent drug at physiological conditions of 37C and pH 7.2 driven by their inherent chemical instability without the need of any enzymatic cleavage. The diketopiperazine and diketomorpholine (DKP and DMP) strategies for prodrug conversion are demonstrated in detail with special emphasis on the chemical flexibility that it offers to develop prodrugs with variable time actions.This book will be of usefulto chemists, biochemists, medicinal chemists, biologists and people in the medical profession (doctors). It may be used in undergraduate classes but will certainly help post-graduate students and advanced professionals. The author is grateful to Prof. Richard DiMarchi (Standiford H. Cox Professor of Chemistry and the Linda & Jack Gill Chair in Biomolecular Sciences at Indiana University) for valuable suggestions. The foreword for the book has been written by Prof. Jean Martinez, (Legion d'Honneur awarded by the French Republic; Professor of Chemistry and Medicinal Chemistry of the University of Montpellier, France; and Chairman of European Peptide Society, 2002-2010).

The field of peptide based cancer vaccines has evolved tremendously in the last decade of this century. The exploration on how to apply the peptide knowledge for vaccination purposes began when it was demonstrated that these peptides after being mixed into adjuvants actually induced T cell responses that could prevent virus infections and tumor growth in experimental animal models. The results of animal models are currently translated into clinical applications with all their associated difficulties and heterogeneity. Initial promising data do appear, warranting further research in this area. This book pays tribute to key researchers in the field.
