Effect of fluorinated tetrahydrocarbazole derivatives on the enzymes of oxidative deamination of biogenic amines and on the process of lipid peroxidation

Abstract

The effect of two fluorinated derivatives of tetrahydrocarbazoles on mitochondrial en-zymes catalyzing the oxidative deamination of biogenic amines such as monoamine oxidase A and B (MAO-A and MAO-B) has been investigated. A dose-dependent effect of the studied compounds on the enzymatic activity MAO-A was shown. It was revealed that both com-pounds are MAO-B inhibitors. Inhibition mechanisms were established and MAO-B inhibi-tion constants were calculated. The above derivatives exhibit strong antioxidant and antirad-ical activity.
