Psychotropic properties of CA-7043× and CA-7050×, new fluorinated derivatives of tetrahydrocarbasoles, were examined on outbred CD1 mice and transgenic 5×FAD mice with Alzheimer disease. Both agents exerted cognitive-stimulating and anxiolytic effects in a dose of 5 mg/kg. In the new cage test, they retarded extinction of orientation and exploratory behavior. CA-7043× produced an anxiolytic effect on CD1 mice assessed in the open-field test and exerted cognitive-stimulating action in the new location test. In the same tests, CA-7050× demonstrated the cognitive-stimulating and anxiolytic effects on transgenic 5×FAD mice.
Keywords: behavioral tests; cognitive-stimulating action; fluorinated derivatives of tetrahydrocarbasoles; transgenic mice.
