Abstract

The aim of the study was to study the effect of GABA derivatives on the functional activity of intact and oxidative stress-damaged mitochondria. Isolated mitochondria were obtained by differential centrifugation. Oxidative damage was simulated by incubation with tert-Butylhydroperoxide (200 nmol/ml, 10 min). The studied substances (baclofen, mefebut, neuroglutam, RGPU-238 compound, salifen, tolibut, phenibut, phenotropil) were added to intact and damaged mitochondria (1*10-5 M per 100 μl, 10 min of incubation), the functional state of mitochondria was studied using a polarographic method. It was revealed that salifen and phenotropil had a pronounced protective effect on the respiratory complexes of the electron transport chain.
