- Synthesis and biological activity of 5-styryl and 5-phenethyl-substituted 2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indoles
-
Syntheses, biological evaluation, and structure-activity relationships for a series of novel 5-styryl and 5-phenethyl analogs of dimebolin are disclosed. The novel derivatives and dimebolin share a broad spectrum of activities against therapeutically relevant targets. Among all synthesized derivatives, 2,8-dimethyl-5-[(Z)-2-phenylvinyl]-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]in dole and its 5-phenethyl analog are the most potent blockers of 5-HT7, 5-HT6, 5-HT2C, Adrenergic α2 and H1 receptors. The general affinity rank order towards the studied receptors was Z-3(2) > 4(2) ≥ 4(3) ? dimebolin, all of them having highest affinities to 5-HT7 receptors.

- LIGANDS OF ALPHA-ADRENOCEPTORS AND OF DOPAMINE, HISTAMINE, IMIDAZOLINE AND SEROTONIN RECEPTORS AND THE USE THEREOF
-
The invention relates to novel ligands the broad spectrum of biological activity of which includes simultaneously α-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 substituted CH2-CH=CH group, C≡C group, SO2 group; n = 1, 2; m = 1, 2, 3; solid line accompanied by dotted line, i.e. (---) may represent single or double bond. The invention also relates to active ingredients, pharmaceutical compositions comprising the said ligands as active ingredients; to novel medicaments useful for treatment of diseases and conditions of central nervous system (CNS) of humans and warm-blooded animals.
