[Toxicity and radiation protective properties of 2(3)-guanidinoalkanethiols: structure-activity].

: In experiments with mice radioprotective properties and toxicity of 2(3)-guanidinoalkanethiols were investigated by exposure to gamma-irradiation in the dose of 6.4 Gy. The obtained results allow to find an association between radioprotective activity of 2(3)-guanidinoalkanethiol compounds and their structure and toxicity.
