Abstract
The aim of the study was determination of correlation between activities: anticonvulsant, analgesic, antidepressant and anxiolytic, among novel compounds, as well as finding mechanism of action of these compounds. Premise for the above aim constitutes coexistence and common etiology of these disorders, such as trauma, intoxication, or neurodegeneration. Among epilepsy patients, morbidity in migraine is 2.4 times as high as between patients who have no seizures. 20-50% of epilepsy patients suffer from depression. Special situation is observed for patients such as children or pregnant women, as well as those who suffer from drug-resistant epilepsy. It is known that anticonvulsants such as carbamazepine, valproates, or gabapentin improve mood and that tianeptine may cause depression. On the other hand, epilepsy can be caused by maprotyline and klomipramine. Drugs such as venlafaxine and selective serotonin reuptake inhibitors are considered relatively safe. Based on our experience regarding aroxyalkyl- and aroxyethoxyethylaminoalkanols and their anticonvulsant and analgesic activity, new phenoxyalkyl and phenoxyethoxyethyl derivatives of piperazine have been designed and synthesized for in vivo screening for epilepsy (maximal electroshock, MES), neurotoxicity (rotarod), antidepressant-like activity (Porsolt test), as well as anxiolytic activity (four-plate test) have been examined. Receptor profile for the compounds has been determined. As an additional assay, mutagenic activity was excluded. Moreover, metabolic stability was determined with use of murine liver microsomes for the most active compounds.
