Angew. Chem. Int. Ed. 2012, 51 (10) 718-722
Résumé :
“Click” protein: CuI-catalyzed cycloaddition of azides and terminal alkynes has been applied to the successive ligations of three unprotected peptide fragments. Peptidomimetic triazole ligation (PTL, see scheme) as a new method for the chemical production of bioactive proteins is applied for the synthesis of a triazole-containing analogue of the 97 amino acid protein cystatin A.
