Abstract:
It was found that the diterpene alkaloid songorine administered per os to mice at a dose of 25 μg/kg provides a pronounced anxiolytic effect during elevated plus maze testing comparable to the effect of the benzodiazepine anxiolytic phenazepam. Recording of ultrasonic vocalizations of animals revealed an increase in the number of short high-frequency (50 kHz) signals under the action of songorine and the reference drug, which confirms their anti-anxiety properties.
