This study designed and synthesized a new compound, LQFM192, and evaluated its anxiolytic and antidepressant activities, as well as the possible mechanisms of action. The results showed that LQFM192 exhibited anxiolytic and antidepressant effects, which were mediated by the serotonergic system and the benzodiazepine site of the GABA(A) receptor.
Background: Pharmacological treatments for mental disorders, such as anxiety and depression, present several limitations and adverse effects. Therefore, new pharmacotherapy with anxiolytic and antidepressant potential is necessary, and the study of compounds capable of interacting with more than one pharmacological target may provide new therapeutic options. Objectives: In this study, we proposed the design, synthesis of a new compound, 2-(4-((1- phenyl-1H-pyrazol-4-yl)methyl)piperazin-1-yl)ethyl acetate (LQFM192), pharmacological evaluation of its anxiolytic-like and antidepressant-like activities, as well as the possible mechanisms of action involved. Methods: Administration of LQFM192 was carried out prior to the exposure of male Swiss mice to behavioral tests, such as the elevated plus-maze and forced swimming test. The involvement of the serotonergic system was studied by pretreatment with WAY-100635 or p-chlorophenylalanine (PCPA) and the involvement of the benzodiazepine site of the GABA(A) receptor by pretreatment with flumazenil. Results: The treatment with LQFM192 at doses of 54 and 162 mu mol/kg demonstrated anxiolyticlike activity that was blocked by WAY-100635, PCPA, and flumazenil pretreatments. The potential antidepressant-like activity was visualized at the same doses and blocked by WAY-100635 and PCPA. Conclusion: In summary, the anxiolytic-like activity of LQFM192 is mediated by the serotonergic system and the benzodiazepine site of the GABA(A) receptor, and the antidepressant-like activity through the serotonergic system.
