Stapled peptide

The synthesis difference between stapled peptide and the normal linear peptide lies in being introduced the two non natural amino acids containing a-methyl and a-alkenyl in the process of solid phase synthesis.Then the two non natural amino

acids occur olefin metathesis cyclization to form stable a-helix conformation of the carbon to synthesize stapled peptide.




The two pictures above are non natural amino acids with two different structures of containing a-methyl and a-alkenyl.

Please focus on the below synthesis method of these amino acids :



The synthetic route of stapled peptide :


We always adheres to the customer first business philosophy. Through accumulation of long years experiment, constantly optimization of the synthesis conditions and the purification technology, we already have a mature method of stapled peptide synthesis to provide highquality stapled peptides fully meeting the needs of customers in different kinds of research and development area.
