Abstract: The invention relates to antagonists of serotonin 5-HT6 receptors simultaneously regulating homeostasis of Ca+2 ions in cells, representing substituted 2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indoles of the general formula 1, pharmaceutically acceptable salts and/or hydrate thereof. In the general formula 1: R1 represents amino group substituent selected from optionally substituted C1-C5 alkyl; R2i is one or more substituents selected from hydrogen, halogen, C1-C3 alkyl, CF3, OCF3; Ar is phenyl optionally substituted with halogen, C1-C6 alkyl, C1-C6 alkoxy, substituted amino group, or CF3; or optionally substituted aromatic 6-membered heterocycle comprising 1-2 nitrogen atoms in the cycle; W represents ethylene group —CH2—CH2—, ethenyl group —CH?CH—, or ethynyl group —C?C—. The invention also relates to the novel compounds selected from the compounds of the general formula 1, methods for their preparation, pharmaceutical compositions and methods of their use.

Abstract: The invention relates to novel substituted indoles, to the use thereof in the form of pharmacological composition substances and to use of said composition for producing medicinal preparations used for preventing and treating viral diseases, in particular caused by viruses of infectious hepatitis (HCV, HBV), human immune deficiency (HIV), atypical pneumonia (SARS) and bird flu.

Abstract: The invention relates to novel heterocyclic compounds and to the use thereof, to pharmaceutical compositions containing said chemical compounds as an active ingredient and to the use thereof for producing medicinal preparations for the human being and warm-blood animals for treating diseases caused by the aberrant activity of an Hedgehog (Hh)-signal system, in particular oncological diseases. The invention also relates to the use of the above-mentioned compounds in the form of ‘molecular pharmacological tools’ for examining (in vitro and in vivo) the biochemical features of the Hh-signal system, in particular, the interaction of Hh protein and transmembrane proteins, namely, suppressor Patched (Ptc) and protooncogenic proteins.

Abstract: 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.

Abstract: The invention relates to novel ligands the broad spectrum of biological activity of which includes simultaneously ?-adrenoceptors, dopamine receptors, histamine receptors, imidazoline receptors and serotonin receptors, among them serotonin 5-HT7 receptors, which are compounds of general formula 1 in the form of free bases, geometrical isomers, racemic mixtures or individual optical isomers, pharmaceutically acceptable salts and/or hydrates, wherein: R1 is a substituent of amino group, selected from hydrogen, optionally substituted C1-C4 alkyl, acyl, heterocyclyl, alkoxycarbonyl, substituted sulfonyl; R2 is a substituent of cyclic system, selected from hydrogen, halogen, optionally substituted C1-C4 alkyl, CF3, CN, alkoxy, alkoxycarbonyl, carboxyl, heterocyclyl or substituted sulfonyl; Ar is optionally substituted aryl not necessarily annalated with heterocyclyl, or optionally substituted aromatic heterocyclyl; W is optionally substituted (CH2)m group, optionally substituted CH?CH group, optionally subst
