Title: Comparative behavioral toxicity of four sulfhydryl radioprotective compounds in mice: Wr2721, cysteamine, diethyldithiocarbamate, and n-acetylcysteine

Technical Report ·
OSTI ID:5646087

A number of sulfhydryl compounds have been shown to protect against ionizing radiation. One of the most effective radioprotectors is S-2(3-aminopropylamino)ethylphosphorothioic acid, also known aas ethiofos, gammaphos, or WR-2721 (Davidson, 1980; Giambarresi and Jacobs, 1987). This drug is currently under clinical investigation for its potential in protecting normal tissue during radiation treatment and chemotherapy (Blumberg et al., 1982; Glover et al., 1988; Yuhas et al., 1980). B-Mercaptoethylamine (MEA, cysteamine) was for years the standard against which the effectiveness of other radioprotectors was judged, but is more toxic than WR-2721 (Giambarresi and Jacobs, 1987). Diethyldithiocarbamate (DDC) and N-acetylcysteine (NAC) are other compounds shown to have radioprotective properties (Milas et al., 1988; Weiss et al., 1984). Studies in a variety of animal species have shown significant behavioral toxicity after administration of WR-2721 (Bogo et al., 1985; Bogo, 1988; Landauer et al., 1987b, 1988).
