Background:

  • Head-to-tail cyclic peptides exhibit high affinity binding to multiple, unrelated receptor classes.
  • This characteristic suggests their potential as privileged structures in drug discovery.

Purpose of the Study:

  • To review synthetic strategies for macrocyclic cyclic peptides and cyclic dipeptides (diketopiperazines) using combinatorial libraries.
  • To highlight the biological applications of these cyclic peptide structures.

Main Methods:

  • Review of synthetic methodologies for cyclic peptide construction.
  • Exploration of combinatorial library synthesis approaches.
  • Summary of reported biological activities and applications.
