EVALUATION OF ACUTE TOXICITY AND ANXIOLYTIC EFFECT OF A SYNTHETIC DERIVATIVE OF CARVONE
Abstract
Objective: To evaluate the safety of cyano-carvone by means of acute toxicity studies and to investigate its anxiolytic potential. Material and Methods: Swiss male mice were treated with cyano-carvone (v.o) in escalating doses from 25 to 2000 mg/kg and observed for 14 days as regards behavioral changes and mortality rate. After this time period, hematological, biochemical and morphological analyses of the main macroscopic organs were carried out. In addition, other groups of animals were treated with doses of 25, 50 and 75 mg/kg in order to assess locomotor activity, anxiolytic effect and motor coordination. Results: In the Hippocratic test, the compound did not cause any deaths among the mice, thus the LD50 was not determined and clinical signs that emerged were discrete, reversible and observed only in higher doses. Accordingly, hematological and biochemical analyses did not show significant alterations. In the behavioral analysis, it was found a reduction of locomotor activity and a greater number of entries in open arms, as well as a longer time spent with open arms, suggesting an anxiolytic effect. In the Rota-rod test it was observed no change in the permanence time on the spinning rod, as well as no changes were detected for the number of falls. Conclusion: This study demonstrated that cyano-carvone has no acute toxicity, and suggests a possible anxiolytic effect that needs to be further investigated in order to elucidate its mechanism of action.
