title: Chromatographic and mass spectral analysis of the radioprotector and chemoprotector S-3-(3-methylaminopropylamino)propanethiol (WR-151326) and its symmetrical disulfide (WR-25595501).
abstract: Metabolically active forms of the radioprotective and chemoprotective drug S-3-(3-methylaminopropylamino)propylphosphorothioic acid (WR-151327) are S-3-(3-methylaminopropylamino)propanethiol (WR-151326) and its symmetrical disulfide (WR-25595501). This paper describes applications of sensitive and specific procedures such as capillary column gas chromatography with flame ionization detection, electron impact mass spectrometry and liquid chromatography with electrochemical detection for structural characterization and analysis of the active forms of WR-151327. These chromatographic procedures provide reproducible linear calibration graphs for a relatively wide range of concentrations of the active forms of WR-151327. The described procedures will further facilitate in vivo and in vitro investigations of chemoprotective and radioprotective properties of WR-151327 and its active metabolites.
