: The aim of the present study was to research the analgesic activity and effect of new dipharmacophore compounds consisting of substances with proven therapeutic activity, namely nebracetam–ibuprofen ( NRIP ), nebracetam–dexibuprofen ( NRDIP ), nebracetam–niflumic acid ( NRNFA ), and nebracetam–mefenamic acid ( NRMFA ), on the cognitive abilities of rats. Materials and methods : The experimental study was performed in 110 Wistar rats (male/female ratio 50/50%), weighing 180–200 g, and 50 laboratory mice (male/female ratio 50/50%) weighing 18–22 g. The study of the analgesic activity was carried out using the acetic acid writhing test and the hot plate test. The effect on the cognitive abilities of rats was studied using the pattern recognition test in a model of neurotrauma caused by a drop-weight. Results and discussion : It has been shown that the administration of dipharmacophores nebracetam–ibuprofen ( NRIP ), nebracetam–dexibuprofen ( NRDIP ), nebracetam–niflumic acid ( NRNFA ) as well as nebracetam–mefenamic acid ( NRMFA ) in the tested dosages leads to a statistically significant (p&amp;lt;0.05) analgesic action in acetic acid writhing tests and hot plate tests. At the same time, the analgesic activity of the compounds has been shown to conjoin with a statistically significant influence on cognitive functions in the experimental animal groups after simulating a neurotrauma. Conclusion : The dipharmacophore compounds studied in the present research, having analgesic and nootropic effects, can be used as effective and safe analgesics and can also be used for the treatment and prevention of pain syndrome, enhancing the cognitive abilities of healthy people in complicated professional conditions.
