Synthesis and Evaluation of the Neurotropic Activity of New β-Cycloketol Derivatives

Two types of known and new derivatives of substituted β-cycloketols were synthesized; characterized using IR, PMR, and ¹³C NMR spectroscopy; and tested for neurotropic activity. Bioscreening of the compounds was performed. A study of the neurotropic properties of the synthesized new β-cycloketol derivatives revealed that some of them exhibited a pronounced anticonvulsant effect as antagonism of corazol. The compounds were superior in anticonvulsant activity to the well-known drug ethosuximide but inferior to diazepam. Like ethosuximide, the studied compounds did not exhibit central muscle relaxant activity at anticonvulsant doses, unlike diazepam. However, they exhibited psychotropic effects, e.g., pronounced anxiolytic, antidepressant, and activating behavior. The results showed that further searching for neurotropic properties in new polyfunctional cycloketol derivatives was advisable.
