    Separation of enantiomers of drugs by capillary electrophoresis, part 7: Gamma-cyclodextrin as chiral solvating agent (1998)

    Notes: Following an extended chiral drug screening program by capillary zone electrophoresis (CZE), the enantioseparation of 86 racemic drugs was tested with γ-cyclodextrin as a chiral solvating agent. Unified conditions were applied to all experiments. In total, 18 drug racemates were separated, 13 entries thereof that had not been separated at the lower CSA concentration applied in an earlier stage of the project. A comparison of the data with the results obtained for α- and β-cyclodextrin points to the significance of partial penetration (“side-on binding”) of aryl groups into the cyclodextrin cavity.

    Separation of enantiomers of drugs by capillary electrophoresis. Part 4: Hydroxyprpyl-gammacyclodextrin as chiral solvating agent (1997)

    Notes: In an extended chiral drug screening program, enantioseparation of 86 racemic drugs was tested with hydroxypropyl-γ-cyclodextrin as chiral solvating agent (CSA). A total of 30 drugs out of 86 could be resolved in this straightforward approach. The number of experiments performed under identical conditions allows a statistical treatment of the data. The enantioseparation of the analytes is correlated with their interaction strength with the CSA. Hence, the concentration of the CSA is a crucial parameter for optimization of the enantioseparation, as shown by a subset of 23 examples.

    Notes: ---Following an extended screening project, 86 racemic drugs were investigated by capillary zone electrophoresis in the presence of the chiral solvating agent (CSA) hydroxypropyl-β-cyclodextrin. A total of 42 drugs out of 86 tested was thereby separated into enantiomeric pairs. Statistical analysis of the numerous experiments performed un der identical conditions reveals a loose correlation of the migration separation factor (αm) with the migration retardation factor (Rm). For a subset of 23 drugs, a drop in the concentration of the CSA was also studied, showing the way to further optimization.
