title: [Toxicity and radioprotective properties of 3,4,5,6-tetrahydropyrimidine and 3,6-dihydropyrimidine derivatives].
abstract: Acute toxicity and radioprotective properties of 16 derivatives of tetrahydro- and dihydropyrimidines were studied in experiments on mice. Hydroiodides of 4,6,6-trimethyl-3,R-2-methylthio-3,6-dihydropyrimidines were shown to be more toxic than respective hydroiodides of 4,6,6-trimethyl-3-R-2-methylthio-4-oxy-3,4,5,6-tetrahydropyrimidines. Four compounds exhibited moderate radioprotective properties.
