Radioprotective Effect of Sodium Hydrogen S-(2-L-Pyrrolidyl-methyl) phosphorothioate in Mice

抄録

Several aminoethyl and pyrrolidylmethyl thiosulfate and thiophosphate derivatives were synthesized and tested for the radioprotective effect in X-irradiated mice. Sodium hydrogen S-(L-2-pyrrolidylmethyl) phosphorothioate was most protective among ten compounds tested. It was effective to a same extent as cysteamine which is a typical radioprotector. N-Methylpyrrolidyl derivative of the compound was completely inactive. Furthermore, no radioprotection was observed in case of the corresponding thiosulfate.
