[The effect of isotheoline on mouse behavior under test conditions for detecting its anxiolytic activity].
The effect of isotheolin, a glaucin derivative, on the behavior of mice was studied under conditions of a model of preference of the dark section of the chamber to the light one which is used for appraisal of the anxiolytic/anxiogenic activity of substances. Intraperitoneal injection of isotheolin in a dose range of 0.25-4 mg/kg antagonized the anxiogenic effect induced by the serotonin agonist [correction of antagonist] chlorophenylpiperazine, mCPP (4 mg/kg). In a dose of 4 mg/kg isotheolin has an anxiolytic effect on intact animals. Bearing in mind that mCPP produces its anxiogenic effect via the 5-HT2C receptors, it is suggested that the mechanism of the anxiolytic action of isotheolin is realized through its interaction with the serotoninergic system at the level of 5-HT2C receptors.
