Novel prodrugs for the intracellular delivery of zidovudine monophosphate (AZTMP) have recently been designed. To investigate the bioconversion and pharmacokinetic profiles of these compounds, an analytical method for the simultaneous determination of zidovudine (AZT) and AZTMP in mouse plasma and peripheral red blood cells was developed. Mouse whole blood samples were treated with TBAHS, EDTA and NaH2PO4, and separated into plasma and red blood cell portions. Samples were processed by solid-phase extraction using Bond Elut C18 cartridges. Chromatography was performed using an Hypersil ODS column and a mobile phase of 2.9% (v/v) acetonitrile and 97.1% (v/v) phosphate buffer, pH 7.50, with UV detection at 267 nm. The average extraction recoveries of AZTMP and AZT in plasma were approximately 85% and 97% over their linear ranges of 0.05-5 microg/ml and 0.125-25 microg/ml, respectively. Extraction recoveries of AZTMP and AZT from peripheral red blood cells averaged 56 and 69% over their linear ranges of 0.125-5 microg/ml and 0.125-25 microg/ml, respectively. The accuracy of the assay was 90-100%. The intra- and inter-day variations of the assay were less than 14%. The analytical method was found to be applicable, reliable and suitable for pharmacokinetic studies.
