bromantane and bemethyl

In experiments on nonlinear male mice the ability of new derivatives of nitrogen-containing heterocyclic compounds to increase the physical working capacity in conditions of hyperthermia, hypothermia and acute normobaric hypoxia and hypercapnia has been investigated. It is established, that pyridine derivative IBHF-11 has more expressed positive action in the said conditions. It provided increase of the working capacity of animals at all kinds of extreme influence, and the value of positive action was comparable, and in conditions of acute normobaric hypoxia and hypercapnia exceeded those at the reference products bemitil and bromantan.

Effects of 21 phenyl ethyl-substituted derivatives of 3-oxypyridine (3-OP), 6 adamantine derivatives of pyridine (PD) and actoprotectors bemithyl and bromanthane on physical performance (PP) were evaluated during treadmill testing of mice in ordinary conditions and following vibration. It was stated that in ordinary conditions PP was improved by eleven 3-OP derivatives and 3 adamantine PDs; nine 3-OP derivatives and 3 adamantine PDs had a positive effect following vibration. The actoprotective effect of the compounds depends on their chemical composition, dose and a background. A phenyl ethyl-substituted 3-OP derivative (code CK-132) administered in ordinary conditions and following vibration surpassed significantly the other compounds tested or compared with (bemithyl and bromanthane) in this experiment with regard to the spectrum of effective doses (5-100 mg/kg) and the actoprotective activity (PP improved by 32 to 110%). The compound (code CK-132) can be further test validated as an actoprotector against the impacts of vibration.

A group of volunteers was exposed to coaction of carbon dioxide (concentration 300 mg/cu m) and heating microclimate (ambient temperature +50 +/- 2 degrees C, relative humidity 20 +/- 5%), simultaneously they received one of the medicines: placebo, bemitil (0.5 g), bromantane (0.25 g) or bemitil (0.5 g) combined with bromantane (0.25 g). Bromantane (0.25 g) or bemitil (0.5 g) combined with bromantane (0.25 g) were proved to be the most effective method to increase stability of the human body against co-action of carbon dioxide and heating microclimate.
