Antihypoxic properties of condensed benzimidazole derivatives with antioxidant activity

Abstract

Hypoxia plays an important role in the vital activity of the organism and practically accompanies any pathology. Hypoxia and tissue ischemia in the early stages are accompanied by the activation of lipid peroxidation. Derivatives of 9-dialkylaminoethyl imidazobenzimidazole with a 3,4-dioxyphenyl substitute showed high antioxidant activity. Therefore, they have been studied for antihypoxic activity in experimental models of hypobaric, histotoxic and hemic hypoxia, as well as in animals pre-typed for resistance to hypoxia, and it was shown that new condensed benzimidazole derivatives with antioxidant activity showed a wide range of antihypoxic activity. The most pronounced protective antihypoxic properties were demonstrated by compound RU-185.
