Neuropharmacological and neurochemical evaluation of N-n-propyl-3-ethoxyquinoxaline-2-carboxamide (6n): a novel serotonergic 5-HT3 receptor antagonist for co-morbid antidepressant- and anxiolytic-like potential using traumatic brain injury model in rats

Abstract

Several preclinical studies have shown that serotonergic 5-HT3 receptor antagonists play an important role in the management of neuropsychiatric disorders, such as depression and anxiety. In the present study the compound “6n” (N-n-propyl-3-ethoxyquinoxaline-2-carboxamide), a novel 5-HT3 receptor antagonist with an optimal log P (2.52) and pA2 (7.6) value was screened for its neuro-pharmacological potential in chronic rodent models of depression and anxiety named traumatic brain injury (TBI).
