HPLC determination of a novel aroylhydrazone iron chelator (o-108) in rabbit plasma and its application to a pilot pharmacokinetic study

Abstract

In this study a high performance liquid chromatographic method for the determination of a biocompatible iron chelator, pyridoxal 2-chlorobenzoyl hydrazone (o-108), in rabbit plasma was developed and validated. The separation was achieved on a C18 column with the mobile phase composed of a mixture of 0.01 M phosphate buffer (pH 6) with the addition of EDTA (2 mM), methanol and acetonitrile (42:24:14; v/v/v).

This method was successfully applied to the analysis of the samples obtained from a pilot pharmacokinetic experiment, in which the chelator was administered intravenously to rabbits.
