Biologically Active Cyclic Peptide Natural Products

Current efforts are being directed towards the synthesis of several complex cyclic peptide natural products. The ustiloxins & celogentins are tubulin-binding cyclic peptides that have shown potent in vitro anti-tumour activity. The echinocandins and microsclerodermins are antifungal cyclic peptides that contain several poly-hydroxylated amino acids, with several now in clinical use for the treatment of fungal infections. The general synthetic strategy involves developing methods for the stereocontrolled synthesis of the highly functionalised amino acid residues present in these peptides, followed by the development of procedures for the assembly of the amino acid components into the final cyclic peptides. We have recently prepared the dityrosine-containing cyclic peptide natural product mycocyclosin, combining our interests in dityrosine crosslinks and peptide natural products!
