Why Cyclic Peptides Matter
The reason researchers remain focused on designing well-structured cyclic peptides is simple: cyclic peptides have favourable drug-like properties and broad therapeutic potential. Whether we are designing the sequence of the cyclic structure with specific amino acids that favor beta-turns or utilizing high-affinity, redox-insensitive, cyclic peptides to target signaling proteins, the precision now available is unprecedented.
