Synthesis of thiocarbamide derivatives of. beta. -alanine and aminalon and study of their antiradiation action
1986
The authors have synthesized the carboxyl derivatives of S-(2-Amino-ethyl)isothiourea (AET) and S-(3-Aminopropyl)isothiourea (3-APT), the dihydrobromides of S-(1-carboxy-2-aminoethyl)- and S-(1-carboxy-3-aminopropyl)isothioureas, and studied their toxicity and antiradiation effectiveness. Their work is based on data for the high radiation-protective activity of the corresponding aminoalkylisothioureas and on the fact that the introduction of the carboxylic group into the molecule influences the pharmacological properties of a compound. The starting compound for the preparation of S(1-carboxy-2-aminoethyl)isothiourea was beta-alanine. Mice were used in the investigations and in determining the toxicity of the compounds, the amounts of LD/sub 16/, LD/sub 50/, and LD/sub 84/ are given. In studying the anti-radiation activity, the mice were subjected to the action of /sup 60/Co-gamma rays.
