title: [General characteristics and comparative evaluation of the radioprotective properties of aryl alkyl amine adrenomimetics in experiments on mice].
abstract: The radioprotective effect (RPE) of some arylalkylamines (AAAs) was studied in experiments on mice. Mesaton and its close analogues were injected subcutaneously 15 minutes prior to irradiation at a dose of 800 rad. The protective effect is exerted by AAAs in low doses (25--50 mumole/kg), the compounds show stable and high RPE (80--80% survival, dose reduction factor being 1.3--1.4) and low toxicity (LD50 = 4--8 mumole/kg). AAAs studied are not less effective than aminothiols. Their pharmacological spectrum--K = LD50/ED50 (200--500) is superior to that of known aminothiols and indolylalkylamines.
