Abstract
The purpose of this study, the direct separation of aminoalkanol derivatives I and II of 1,7‐dimethyl‐8,9‐diphenyl‐4‐azatricyclo[5.2.1.02,6]dec‐8‐ene‐3,5,10‐trione, which was found in earlier studies as potential anticancer drugs, were performed. Capillary electrophoresis offers the possibility of fast, cheap, and reproducible separations for compounds I and II. In this paper, the simultaneous separation of I and II by capillary zone electrophoresis has been achieved within 8 min by use of 50 mM phosphate buffer of pH 2.5. Analysis of the two compounds in the serum plasma standards was conducted. Limits of detection of I and II by UV absorbance at 200 nm were achieved in the range of 156.3–156.6 ng/mL. The method was validated for linearity, accuracy, precision, limits of detection, and quantification. The calibration equation revealed a good linear relationship (r2 = 0.998–0.999). Sufficient recovery was observed in the range of 96.3–99.5%. The method showed good reproducibility with intra‐ and interday precision of 0.97 and 1.76%, respectively. The quantification limits for the compounds were in the range of 477.0–479.8 ng/mL. The proposed method was applied to the analysis of real serum samples.
