An important and timely guide to the progress being made on constrained helical peptides
Constraint helical peptides have emerged as a solution to target previously undruggable protein-protein interactions, which feature large and complex surfaces. Cyclized Helical Peptides: Synthesis, Properties and Therapeutic Applications offers a review of the most current methodologies of constructing constrained helices. The authors noted experts on the topic include the information on the fundamental features of cyclized helical peptides and discuss their limitations. The book summarizes and explores the effects of chemical methods constructing helical peptides on helicity, binding affinity, cell penetration, and nonspecific toxicity.
The book examines the therapeutic applications of the constraint helices and includes comparison with existing small molecule modulators or antibodies. Designed as a useful resource for both those outside and inside the field. Those new to the field will find a comprehensive introduction to cyclized helical peptide and those inside the field will find a deeper understanding of the topic.

Autorenporträt
Zigang Li is now a professor in School of Chemical Biology and Biotechnology of Peking University. Before joining Peking University, Li worked as a postdoctoral fellow with Professor Gregory L. Verdine at Harvard University where he focused on discovery of new targets from human cancer cells for stapled peptides. Li received his PhD with Professor Chuan He at the University of Chicago in 2008 where he investigated global regulator functions on the pathogenesis of Staphylococcus aureus. Before that, Li performed his master studies at Tulane University, where he studied with Professor Chao-Jun Li on imine reactivity in aqueous media. Li completed his undergraduate degree of biophysics at The University of Science and Technology of China. Li's research interests include peptide based drug discovery and new strategies against infectious disease. Hui Zhao is now a postdoc in Shenzhen GTJA Investment Group (GIG), with 3 years of experience in industry research and investment, in the field of innovative drugs and medical devices. He obtained his PhD degree in chemical genomics from Peking University under the supervision of Prof. Zigang Li in 2017. His main research direction was peptide science, with papers published in academic journals and patents applied. Chuan Wan is a post-doc under the supervision of Prof. Zigang Li. He got his BS and Ph.D degree from China Agricultural University in 2012 and 2018, respectively. His main research interests focus on development of novel bio-orthogonal chemistry, research on peptide-stapling methodology and self-assembled materials based on stabilized a-helical peptide.
