  • Title: New chiral stationary phase with macrocyclic glycopeptide antibiotic eremomycin chemically bonded to silica.
    Author: Staroverov SM, Kuznetsov MA, Nesterenko PN, Vasiarov GG, Katrukha GS, Fedorova GB.
    Journal: J Chromatogr A; 2006 Mar 10; 1108(2):263-7. PubMed ID: 16464461.
    Abstract:
    A new chiral stationary phase (CSP) was prepared by attachment of macrocyclic glycopeptide antibiotic eremomycin to the epoxy-activated silica under mild conditions. In contrast to CSP with immobilized vancomycin, which is a close structural analogue of eremomycin, the prepared CSP reveals high enantioselectivity for separation of amino acids enantiomers. It was demonstrated by the example of ristocetin A CSP that method of the immobilization of macrocyclic glycopeptide antibiotics affects remarkably the resulting enantioselectivity.
