The compound, administered at doses of 4, 20 and 40 mg/kg, did not show toxicity after 96 h of monitoring. In behavioural experiments with zebrafish, robinin did not cause significant changes in motor functions, but it impairs locomotor activity and demonstrates anxiolytic properties, evidenced by the increase in the time spent in the clean zone of the protector. A minimum effective dose (4 mg/kg) was blocked by flumazenil (FMZ), providing interaction with GABAA receptors and decreasing an anxiolytic profile similar to that of diazepam, without causing sedation. In addition, a dose of 40 mg/kg was able to reverse seizures, increasing the latency to enter the seizure stages, an effect that was also blocked by FMZ. Robinin (40 mg/kg) also prevented memory variation in an inhibitory avoidance test. In silico absorption, distribution, metabolism and excretion tests indicated that robinine presents gradual intestinal absorption and low distribution in the central nervous system. In molecular docking, the compound was exposed in the layer with CAII and GABAA receptors, corroborating the anxiolytic and anticonvulsant effects. The results suggest that robinine has therapeutic potential in the treatment of anxiety and seizures, in addition to offering memory protection, representing an advantageous alternative to benzodiazepines, with a promising neuroprotective potential for the pharmaceutical industry. |
