Taking into account that the imidazole ring has π-electron redundancy, condensed benzimidazole derivatives have attracted our attention as a promising class for the search for antioxidant substances. Synthesis was carried out, and information on the antioxidant activity of imidazo- and tetrahydropyrimido benzimidazoles was provided. Highly active antioxidant substance enoxifol has been revealed. The data on the synthesis and study of the pharmacodynamic, pharmacokinetic, and toxicological properties of the new antioxidant compound enoxifol are presented. The antioxidant activity of the compound is due to its ability to inactivate superoxide, hydroxyl, and peroxyl radicals, thereby reducing the overall oxidation rate due to a decrease in the total initiation rate. It has been shown that enoxifol has hepatoprotector, antihypoxic, cerebroprotective, nootropic, stress-protective, neuropsychotropic, actoprotective, cardioprotective, antiaggregant, and antithrombogenic properties and is able to prevent rheological disorders in diabetes mellitus.
