  • Title: Enantioseparation using sulfated cyclosophoraoses as a novel chiral additive in capillary electrophoresis.
    Author: Park H, Lee S, Kang S, Jung Y, Jung S.
    Journal: Electrophoresis; 2004 Aug; 25(16):2671-4. PubMed ID: 15351997.
    Abstract:
    Highly sulfated cyclosophoraoses (HS-Cys) were synthesized by the chemical modification of a family of neutral cyclosophoraoses isolated from Rhizobium leguminosarum bv. trifolii. The HS-Cys were then analytically characterized using Fourier transform-infrared spectroscopy and elemental analysis. These HS-Cys were successfully used as a novel chiral additive, in low-pH aqueous background electrolytes, for capillary electrophoretic separation of five basic chiral drugs such as arterenol, atenolol, isoproterenol, propranolol, and metoprolol.
