Methods for the analysis of the new vinca alkaloid derivative, S 12363, in plasma by high-performance liquid chromatography with fluorescence detection.
Two sensitive analytical methods for the analysis of S 12363 in plasma are described. A highly sensitive procedure for human and dog plasma using cyanopropyl solid-phase extraction with ion pairing chromatography and fluorescence detection, has a limit of quantification of 0.1 ng ml-1. The technique has an overall precision and accuracy of 4.8 and 5.4% respectively over the concentration range 0.1-20 ng ml-1. A second, less sensitive, assay specifically adapted for rodent plasma, uses benzene sulphonyl cation-exchange solid-phase extraction followed by reversed-phase chromatography, with post-column fluorescence enhancement. This method has a limit of quantitation of 1.0 ng ml-1, with overall accuracy and precision of 7.2 and 11.6% respectively, over the concentration range 1.0-20.0 ng ml-1. Both assays have been successfully applied to dog and mouse toxicokinetic studies.
