Effect of newly synthesized 1,2,4-triazino5,6-bindole-3-thione derivatives on olfactory bulbectomy induced depression in rats

摘要

cqvip:Objective:To study the derivatives of 1,2,4-triazino[5,6-b]indole-3-thione for antidepressant activity in olfactory bulbectomized(OBX)rats.Out of various derivatives tested for acute tail suspension test,the two derivatives showiug prominent action were.selected for bilateral olfactory bulbeetomy rsodel of ehronic depression in rats.Methods:The sub aeute effects of 14-day oral pretreatment of two derivatives labeled as 3a(70 mg/kg)and 3r(70 mg/kg),imipramine(20 mg/kg),fluoxetiue(30 mg/kg)and moclobemide(15 mg/kg)were evaluated on bilateral bulbectomy induced rise in body weight,hyperphagia,hyperactivity,and on sexual dysfunction.The serum sodium concentration,body temperature,and heart rate were also recorded.Results:The derivatives3a and 3r showed reversal of drop in body weight,reversed OBX indueed hyperactivity,normalized body temperature,heart rate,and serum sodium concentration.In elevated maze test,moclobemide,3a,3r treatment significantly redueed time spent in open arm as compared to OBX rats.3a and 3r also irsproved sexual behavior parameters.Conclusions:The present study shows promising antidepressant action and provides a proof of concept for the chronic treatrsent of 3a,3r to treat depression.
