Enger A, Deltour G, Coninx P, Jezekova D, Cattan A, Fournaise R: [Gas-liquid chromatographic assay of a new antineoplastic agent, 1,3,3,5,5-pentakis-(azaridino) lambda 6-2,4,6,3 lambda 5, 5 lambda 5-thiatriazadiphosphorine-1-oxide. J Chromatogr. 1984 Feb 10;305(2):335-44.
Application to pharmacokinetic studies]. A method for the assay of 1,3,3,5,5-pentakis-(azaridino)-lambda 6,2,4,6,3 lambda 5,5 lambda 5-thiatriazadiphosphorine-1-oxide (SOAz), a new anticancer drug of which the clinical trials are in progress, is described. This method is based on capillary gas chromatography using a thermionic detector. The lower detection limit was 100 pg per injection and a coefficient of variation smaller than 5% could be obtained when parathion was used as external standard. The method is suitable for biological samples and therefore has been proposed for clinical pharmacokinetic studies as well as for the determination of patterns of SOAz distribution in several organs of the mouse. A preliminary clinical study showed that the serum decay curves of SOAz could be fitted to an open two-compartment model for drug disappearance. |
