Synthesis of n-substituted derivatives of 1-(4-methoxyphenyl)-1,5-dihydro-4н- pyrazolo[3,4-d]pyrimidin-4-one as potential anticonvulsants

Abstract

The high psychotropic activity of pyrimidine derivatives attracts attention and leads to the creation of new pyrimidine drugs which affect the central nervous system. As psychotropic agents, special attention deserve azolopyrimidine derivatives, including pyrazolopyrimidines. Thus, among the pyrazolopyrimidine derivatives, compounds with antiepileptic, anticonvulsant, sedative, anxiolytic activity, ligands of benzodiazepine site of GABA receptors have been found. In addition, the ligands of 5HT-6 receptors were identified that are promising for the treatment of central nervous system, muscle relaxants. The purpose of this research was a synthesis of alkylated derivatives of 1-(4-methoxyphenyl)-1,5-dihydro- 4H-pyrazolo[3,4-d]pyrimidine-4-ones
