Aim: The present study was designed to investigate the anxiolytic activity of 6g, a novel serotonin type-3 receptor (5-HT 3 ) receptor antagonist in experimental mouse models of anxiety. Materials and Methods: The anxiolytic activity of "6g" (1 and 2 mg/kg, intraperitoneally [i.p.]) was evaluated in mice by using a battery of behavioral tests of anxiety such as elevated plus maze (EPM), light-dark (L&D) box, hole board (HB), and open field test (OFT) with diazepam (2 mg/kg, i.p.) as standard anxiolytic. None of the tested dose of "6g" affects the base line locomotion. Results: The new chemical entity "6g" (2 mg/kg, i.p.) and diazepam (2 mg/kg, i.p.) significantly (P < 0.05) increased the percentage of time spent and number of entries in open arm in the EPM test. In the L&D test compound "6g" (2 mg/kg, i.p.) and diazepam (2 mg/kg, i.p.) significantly (P < 0.05) increased the total time spent in light compartment as well as number of transitions from one compartment to other. Compound "6g" (1 and 2 mg/kg, i.p.) and diazepam (2 mg/kg, i.p.) also significantly (P < 0.05) increased number of head dips, whereas significantly (P < 0.05) decreased the head dipping latency in HB test as compared to vehicle control group. In addition, 6g (2 mg/kg, i.p.) and diazepam (2 mg/kg, i.p.) significantly (P < 0.05) increased the ambulation scores (square crossed) in OFT and there was no significant effect of 6g (1 and 2 mg/kg, i.p.) and diazepam (2 mg/kg, i.p.) on rearing scores. Conclusion: In conclusion, these findings indicated that compound "6g" exhibited an anxiolytic-like effect in animal models of anxiety.
