Actiprotective and antihypoxic action of new heteroaromatic antioxidants

: Expernents with mice showed that most of 15 new heteroaromatic antioxidant compounds possess aciprotective and antixopixic properties. Based on results of treadmill and swimming tests, actiprotective action of IBKhF-1, 11 and 14 surpassed greatly bemythil and bromanthane in ordinary conditions. Inhibitor of gluconeogenase tryptophan cancelled largely the stimulatting action of highly effective and active IBKhF-1, 2 and 11 on physical performance during treadmill exercise. Consequently, gluconeogenesis activation is one of the major components of the actiprotective action of these antioxidants. In addition, IBKhF-1, 11 and 14 excelled bemythil and bromanthane in the extreme conditions of running in hyperthermia and swimming in acute hypoxia combined with hypercapnia. IBKhF-2 and 14 were better than amtisol (standard antihypoxic agent) and bemythil against acute hypoxia in pressure chamber, whereas IBKhF-4 and 14 excelled these agents in thermal chamber.
