Abstract:

Vancomycin and teicoplanin are glycopeptide macrocyclic antibiotics with three-dimensional ring structures and multiple chiral centers. They are commonly used chiral recognition materials in enantioseparation by high-performance liquid chromatography. In this study, six chiral stationary phases wrapped with a net on silica gels were prepared by interfacial polymerization using vancomycin and teicoplanin as chiral selectors, piperazine as a monomer, 4,4'-diphenylmethane diisocyanate (MDI), 1,6-hexamethylene diisocyanate (HDI), and 2,4-toluene diisocyanate (TDI) as crosslinker. The fabricated chiral columns were used for enantioseparations. Compared to the crosslinked and commercial columns composed of vancomycin and teicoplanin, the columns wrapped with a net exhibited complementarity for the optical resolutions.

Key words: chiral stationary phase, high performance liquid chromatography (HPLC), interfacial polymerization, macrocycle antibiotic
