- This invention relates to new 3-apylcylphonyl-pyrazole [l, 5-apyrimidines, to new antagonists of serotonin 5-HT 6 receptors, to new drug substances, pharmaceutical compositions, drugs and methods for their preparation and use. More specifically, the present invention relates to antagonists of serotonin 5-HT 6 receptors - substituted 3-cyclonyl-pyrazole [l, 5-a] pyrimidines, drug substances and pharmaceutical compositions containing drug substances in the form of these compounds, as well as to a method of treatment and preventing the development of various diseases of the central nervous system, including cognitive and neurodegenerative diseases.
- the pharmacological effect of new drug substances is based on their ability to antagonistically interact with serotonin 5-HT 6 receptors, which play an important role in the treatment of central nervous system diseases, in particular, Alzheimer's disease (AD), Gangnton’s disease, schizophrenia, other neurodegenerative diseases, cognitive disorders and obesity .

- 5-HT 6 receptors are modulators of several neurotransmitter systems, including cholinergic, noradrenergic, glutamatergic and dopaminergic. Considering the fundamental role of these systems in normal cognitive processes, as well as their dysfunction during neurodegeneration, the exceptional role of 5-HT 6 receptors in the formation of normal or “pathological” memory becomes apparent. A large number of modern studies have shown that blocking 5-HT 6 receptors leads to a significant increase in memory consolidation in various animal learning-memorizing-reproduction models [Foleu AG, Murphu KJ, Nirst WD, Gallagher HC, Nag JJ, Upton N., Walsh FS, Regan CM.
