Cyclotides: a natural combinatorial peptide library or a bioactive sequence player?

Abstract

In this perspective review, we focalized our attention on the application of cyclotides in drug discovery. To date, two principal approaches have been explored since now: (i) the use of cyclotides as scaffold in which bioactive peptides can be grafted to improve stability, oral bioactivity and binding to GPCRs; (ii) their application as natural peptides library. For these reasons, cyclotides probably represent today a step further in the development of new tools in drug design.
