Effects of Fluorencarbonic Acid Derivative on the Levels of Monoamines and Their Metabolites in Brain Structures of Rats with Modeled Depression-Like State

The effects of the new structural analogue of benactyzine, a derivative of fluorencarbonic acid, on monoamine levels in brain structures were studied in male Wistar rats with experimental depression. Depressive state in rats was modeled by single injection of reserpine (4 mg/kg). The concentrations of norepinephrine (NE), dopamine (DA), serotonin (5-HT), and their metabolites 3,4-dihydroxyphenylacetic acid (DOPAC), homovanilic acid (HVA), and 5-hydroxyindoleacetic acid (5-HIAA) in the hypothalamus and striatum were measured by HPLC. It was found that preliminary treatment (30 days) with the derivative of fluorencarbonic acid prevented a decrease in monoamine level in the hypothalamus (NE, 5-HT, and 5-HIAA) and striatum (DA, 5-HT, and 5-HIAA). The neurochemical shifts (correction of 5-HT deficiency and stabilization of DA and NE levels) correlated with the high antidepressant activity of this agent observed in Porsolt forced swimming test.
