The exchange of monoamines during the experimental neurosis on the background of using of amide 2-hydroxy-n-naphthalen-1-yl-2-(2-oxo-1,2-dihydroindol-3-ylidene)

Abstract

Introduction: Incessant increase in the frequency and distribution of anxiety disorders stipulates searching, research and study of the mechanism of action of new substances for their correction, including the group of 2-oxoindolin-3-glyoxylic acid derivatives. The aim: To research the e²ect of N-(1-naphthyl) amide-2-oxoindolin-3-glyoxylic acid on monoaminergic system of subjected to experimental neurosis of rats. Materials and Methods: The experiments were performed on male Wistar rats, who have weight 180-220g and were researching the e²ect of 2-hydro-N-naphthalen-1-yl-2-(2-oxy-1,2-dihydroindol-3-ylidene)-acetamide (compound 18) at a dose (12 mg/kg), by intragastric drug injection of subjected to experimental neurosis rats, during 30 days (1 time in three days), for monoamines content (epinephrine, norepinephrine, dopamine and serotonin) in the blood, their decay products (homovanillic acid, vanillylmandelic acid and 5-oxyindolacetic acid) in the urine and the ratio of end products of the reaction to their predecessors. Research: It was established that during the preventive-therapeutic application of N-(1-naphthyl)amide-2-oxoindolin-3-glyoxylic acid, it e²ectively adjusts the level of monoamines, reducing the content of adrenaline and increasing the content of noradrenaline, dopamine and 5-HT in the blood. The compound also reduces the content of products exchange of mediators (HVA,VMA and 5-OIAA) in the urine. The 2-oxoindolin derivatives reduces the ratio between HVA/dopamine, VMA/(noradrenaline + adrenaline) and 5-OIAA/5-HT, it testies about the normalizing of enzymes activity, which are involved in the process of exchange and maintaining the constancy of monoamines. The results show that in the mechanisms of anxiolytic action of compound 18, a signicant role plays the normalization of content and exchange of neurotransmitters in the organism, which caused an experimental neurosis. Conclusion: Compound 2-hydro-N-naphthalen-1-yl-2-(2-oxo-1,2-dihydroindol-3-ylidene)-acetamide by the experimental 30-day neurosis, was reducing the expression of neurotransmitter imbalance in the blood, apparently due to correction of enzymatic synthesis links and biotransformation of monoamines.
