The invention relates to novel ligands of 5-HT6
receptor, to a pharmaceutical composition containing said novel ligands of 5-HT6
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-HT6 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-HT6 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; C1-C5-
alkyl optionally substituted by: C6-C10-arylaminocarbonyl, heterocyclyl, C6-C10-arylaminocarbonyl, C6-C10-arylaminothiocarbonyl, C5-C10-azaheteroaryl, optionally substituted carboxyl,
nitryl group, optionally substituted
aryl; R1k represents from 1 to 3 substituents of cyclic
system, independent of each other and selected from
hydrogen, optionally substituted C1-C5-
alkyl, C1-C5-alkoxy, C1-C5-alkenyl, C1-C5-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.
