LIGANDS OF 5-HT6 RECEPTORS, A PHARMACEUTICAL COMPOSITION, METHOD FOR THE PRODUCTION AND USE THEREOF

The invention relates to novel ligands of 5-HT 6 receptor, to a pharmaceutical composition containing said novel ligands of 5-HT 6 receptor as active component and to novel medicaments used for humans and warm-blooded animals for treating diseases and conditions of central nervous system, in pathogenesis of which neuromediator systems induced by 5-HT 6 receptors are playing an essential role. Azaheterocyclic compounds of the general formula 1 or racemates, or optical or geometrical isomers, or pharmaceutically acceptable salts and/or hydrates thereof are used as 5-HT 6 ligands. Wherein R2 and R3 independently of each other represent an amino group substituent selected from hydrogen; substituted carbonyl; substituted aminocarbonyl; substituted aminothiocarbonyl; substituted sulphonyl; C 1 -C 5 -alkyl optionally substituted by: C 6 -C 10 -arylaminocarbonyl, heterocyclyl, C 6 -C 10 -arylaminocarbonyl, C 6 -C 10 -arylaminothiocarbonyl, C 5 -C 10 -azaheteroaryl, optionally substituted carboxyl, nitryl group, optionally substituted aryl; R 1 k represents from 1 to 3 substituents of cyclic system, independent of each other and selected from hydrogen, optionally substituted C 1 -C 5 -alkyl, C 1 -C 5 -alkoxy, C 1 -C 5 -alkenyl, C 1 -C 5 -alkynyl, halogen, trifluoromethyl, CN-group, carboxyl, optionally substituted aryl, optionally substituted heterocyclyl, substituted sulfonyl, optionally substituted carboxyl; the solid line accompanied by the dotted line ( --- ) represents a single or a double bond; n=1,2 or 3.
