    Abstract:
    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). The method was validated with respect to selectivity, linearity (0.8-150 microg/mL), intra- and inter-day variability and stability. 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.
