Today, an increase of natural and technogenic situations leads to the disorders of the central nervous system, functional-metabolic processes, vascular diseases, in particular, acute cerebral blood flow disorders. In addition, the changes occurring on the molecular and cellular levels are in the basis of the functional violations of individual systems and the organism as a whole. Hypoxia not only complicates the disease course, but in most cases, determines its outcome. The important role in the fight against hypoxia belongs to antioxidants, which improve the circulating oxygen utilization by the body, reduce its need for the organs and tissues, which is not only expedient but necessary for the treatment of many acute and chronic pathological processes. So, the frequency of the hypoxic states and a wide range of factors causing them determine the relevance of new ways and methods finding to overcome the oxygen deficiency.

The aim of this work is the purposeful search of some 5-[((5-(adamantane-1-yl)-4-R-4H-1,2,4-triazole-3-yl)thio)methyl]-N-R1-1,3,4-thiadiazole-2-amines and 5-[((5-(adamantane-1-yl)-4-R-4H-1,2,4-triazole-3-yl)thio)methyl]-4-R1-4H-1,2,4-triazole-3-thiols, the study of their physical and chemical properties and pharmacological screening of the antihypoxic activity of the obtained compounds.

Materials and methods. The study of physical and chemical properties was conducted on certified and licensed modern equipment. Antihypoxic activity was studied during the modeling process of hypoxia with hypercapnia. Mexidol was used as a comparison drug in studies at a dose of 100 mg/kg.

Results. As the result of the study, it was found that the synthesized compounds and the comparison drug influenced on rats’ life span differently. Compounds, the antihypoxic activity of which exceeded control have been discovered, and others’ were at the level of Mexidol. A number of compounds showed a somewhat less activity in comparison with control, and two compounds, among the investigated ones were weaker then comparison drug action, but they did not reduce the life expectancy of the investigated groups in comparison with control. The effect of the remaining compounds on the lifetime of the investigated group was at the level of control group that received the physiological solution.

Conclusions. A series of new compounds of derivatives among 5-[((5-(adamantane-1-yl)-4-R-4H-1,2,4-triazol-3-yl)thio)methyl]-N-R1-1,3,4-thiadiazole-2-amines and 5-(5-(adamantane-1-yl)-4-R-4H-1,2,4-triazole-3-yl)thio)methyl)-4-R1-4H-1,2,4-triazole-3-thiols have been synthesized, the structure of which has been confirmed with the help of modern physical and chemical methods of analysis. The most active compounds among the studied ones were 3a and 2a, their antihypoxic activity exceeds control on 37.86 % and 36.30 % and Mexidol is on 7.35 % and 5.79 % respectively.
