Antidepressant-like activity of 2-(4-phenylpiperazin-1-yl)-1, 8-naphthyridine-3-carboxylic acid (7a), a 5-HT₃ receptor antagonist in behaviour based rodent models: evidence for the involvement of serotonergic system.


The present study was designed to investigate the putative antidepressant-like activity of 7a, a 5-HT₃ receptor antagonist, (although indirect evidence of 5-HT3 antagonism) with an optimal log P (3.35) and pA₂ value (7.6) greater than ondansetron (pA₂--6.6) using behavioural tests battery of depression. Acute treatment of 7a (0.5-2 mg/kg, i.p.) in mice… (More)
