Pseudoprolines as Removable Turn Inducers: Tools for the Cyclization of Small Peptides
摘要:
The cyclization of small peptides which do not incorporate turn inducers is often difficult. We have developed a method involving the use of removable turn inducers, in the form of pseudoprolines, for the cyclization of difficult peptide sequences. The pseudoprolines induce a cisoid amide bond in the peptide backbone which facilitates cyclization. They are then readily removed to yield a cyclic peptide that does not contain any turn inducers.

affinity for tetrahedral oxo-anions than halides. 1H NMR spectroscopy indicated that anion binding results in an overall change in peptide conformation with the binding of both sulphate and selenate leading to similar peptide conformations. In the more competitive solvent mixture of 2:8 v/v H2O/DMSO-d 6 this cyclic peptide displayed five-fold stronger binding to sulphate than to selenate. Graphical
