    The influence of substituent position in monocarboxymethyl-gamma-cyclodextrins on enantioselectivity in capillary electrophoresis

  • Original language description

    Three newly synthesized chiral selectors, namely, 2I-O-, 3I-O-, and 6I-O-carboxymethyl-?-cyclodextrin, native ?-cyclodextrin, and commercially available carboxymethylated ?-cyclodextrin with degree of substitution of 3-6 were used as additives in a background electrolyte composed of phosphate buffer at 20 mmol/L concentration and pH 2.5. This systém was used for the analysis of several biologically significant low-molecular-mass chiral compounds by capillary electrophoresis. The results confirmed that the position of carboxymethyl group influences the enantioseparation efficiency of all the studied analytes. The 2I-O- and 3I-O- regioisomers provide a significantly better resolution than native ?-cyclodextrin, while the 6I-O-regioisomer gives only a slightly better enantioseparation than native ?-cyclodextrin. The application of ?-cyclodextrin possessing higher number of carboxymethyl groups led to the best resolution for the majority of the compounds analyzed.
