Enantioseparation in CE using macrocyclic antibiotics as chiral selectors
Enantiomer separation represents an important topic especially in pharmaceutical and environmental fields where many drugs and pesticides are racemic compounds. In some cases, only one of the enantiomers has pharmacological or pesticidal activity while the other may exhibit antagonistic activities, unwanted side effects or even toxic effects. Therefore, the development of new enantioseparation ...
متن کاملAnalysis of antibiotics by CE and their use as chiral selectors: An update.
The widespread use of antibiotics in medicine and as growth-promoting agents has increased the demand for suitable analytical techniques for their analysis. Analytical methods based on CE or miniaturized CE systems have proved over the years their ability for the analysis of antibiotics. Since our last review (Electrophoresis 2014, 35, 28-49) several new CE methodologies have been reported for ...
متن کاملEnantioseparation of ofloxacin in urine by capillary electrokinetic chromatography using charged cyclodextrins as chiral selectors and assessment of enantioconversion.
A method was developed for the enantioseparation of ofloxacin, a member of the fluoroquinolones, using an anionic cyclodextrin-derivative with or without combination with a neutral cyclodextrin-derivative, as the chiral selector (s) in an electrokinetic chromatography system. The best results were obtained with 0.35 mM sulfated beta-cyclodextrin dissolved in a 50 mM phosphate buffer, pH 2.5, an...
متن کاملDesigned combination of chiral selectors for adjustment of enantioseparation selectivity in capillary electrophoresis.
In this study an attempt has been made to explain the reasons for changing the enantioseparation selectivity in some dual cyclodextrin (CD) systems compared to the use of single chiral selectors in capillary electrophoresis (CE). An explanation for selectivity changes is proposed based on the effect of the chiral selector on the mobility of the analyte. In order to support the proposed mechanis...
متن کاملChiral separations.
REVIEWS This review covers developments and applications in chiral separations from January 2000 to March 2002. This review is not intended to be a comprehensive review of all papers published, but focuses on major developments in the field of chiral separations as well as representative applications. The review is restricted to the English language literature except as noted for several specif...
