These experiments continued our line of inquiry into low-toxicity high-effectiveness radiomodifying agents obtained by binding radioprotective substances to biogenic and biologically active components or antidotes. Testes for toxicity and radioprotective effects were three preparations combining within one molecule AET and an adenyl nucleotide (AMP, ADP, or ATP). Ionic-bond formation was shown to have advantages over concomitant administration of AET and adenosine phosphoric acids as mixtures. The evidence obtained supports the rational foundation of the concept being developed by our laboratory.

Aminothiol radioprotectors (MEA, AET, WR-1065) were found to be inhibitors of platelet aggregation. The aim of this study has been to clarify the potential involvement of the adenylate cyclase-cAMP system in this effect. In vitro aminothiol compounds (> 1 mmol/l) inhibited platelet function as well as AC-activity, i.

The sulphur-containing radioprotectors mercaptoethylamine (MEA), aminoethylisothiourea (AET), 2- aminothiazoline , 4-oxo-2- aminothiazoline , and S-S-3- oxapentane -1,5- diisothiourea , and the radioprotective biogenic amines serotonin, histamine, and dopamine, caused the elevation of cAMP content and intensified the rate of cAMP-dependent protein phosphorylation in tissues of animals following intraperitoneal injection at radioprotective doses. Biogenic amines stimulated the adenylate cyclase activity in membrane preparations from liver, spleen, and small-intestine mucosa; sulphur-containing radioprotectors caused no such effects. None of the radioprotectors affected cAMP and cGMP phosphodiesterases in vitro.
