Chiral separation and identification of β-aminoketones of pharmacological interest by high performance liquid chromatography and capillary electrophoresis

This paper describes the development and comparison of chiral methods of analysis for a series of pharmacologically active indane derivatives that have been studied in the context of the evaluation of a promising prodrug system for amines. The methods are intended for studying the differences in the pharmacokinetics of the optical isomers of these compounds. Capillary electrophoresis, using cyclodextrins as chiral selectors, and HPLC, using a Pirkle type stationary phase, were tested. Baseline separation was not achieved by HPLC, but good separations were obtained in less than 7 min, by capillary electrophoresis with phosphate buffers pH 2.5–3 using sulfated-β-cyclodextrin or mixtures of neutral β-cyclodextrins as chiral selectors.
