The Study of Cognitive-Stimulating Activity of Fluorinated Tetrahydrocarbazole Derivatives and Behavioral Responses in Transgenic Tg6799 Mice with Alzheimer’s Disease

The cognitive-stimulating, neuroprotective effects of promising fluorinated tetrahydrocarbazole derivatives (CA-7043x and CA-7050x) on the hippocampus-dependent memory of outbred mice (CD1) and transgenic Tg6799 mice, as well as their effect on anxiety, locomotor activity, and orienting-exploratory behavior of animals, were studied. It was found that both compounds have a pronounced cognitive-stimulating effect on CD1 mice, but do not show neuroprotective effects on memory support in Tg6799 mice. It is noted that, in the open-field test, the CA-7050x compound has a positive effect on the orientating behavior, and the CA-7043x compound has a positive effect on the exploratory response in the nontransgenic control.
