FIELD: chemistry.
SUBSTANCE: present invention relates to novel quinoline compounds of formula 
(I) and physiologically acceptable acid addition salts and N oxides thereof, wherein R denotes a polycyclic group of formula 
(R) wherein * indicates the quinolinyl radical binding site; A denotes (CH2)a, where a equals 0, 1, 2 or 3; B denotes (CH2)b, where b equals 0, 1, 2 or 3; X' denotes (CH2)x where x equals 0, 1, 2 or 3; Y denotes (CH2)y where y equals 0, 1, 2 or 3; provided that a+b=1, 2, 3 or 4, x+y=1, 2, 3 or 4, and a+b+x+y=3, 4, 5, 6 or 7; Q denotes N; R1 denotes hydrogen, C1-C6-alkyl, C3-C6-cycloalkyl-C1-C4-alkyl, phenyl-C1-C4-alkyl, C1-C4-alkylcarbonyl, C1-C4-alkoxycarbonyl, phenoxycarbonyl or benzyloxycarbonyl, where phenyl rings in last two said groups are unsubstituted or carry 1, 2 or 3 substitutes selected from halogen, C1-C4-alkyl or C1-C4-halogenalkyl; R2 denotes hydrogen; R3 denotes hydrogen; p=0, 1 or 2; R4, if present, denotes C1-C4-alkyl and is bonded with X and/or Y, if p=2, two radicals R4, which are bonded with adjacent carbon atoms of X or Y, together can also denote a straight C2-C5-alkylene; q=0; n=0; m=0; X denotes S(O)2; which is located in position 3 of quinoline; Ar denotes a radical Ar1, wherein Ar1 is a phenyl, wherein the phenyl can be unsubstituted or can carry 1 substitute Rx wherein Rx denotes halogen, CN, C1-C6-alkyl, C1-C6-halogenalkyl, C1-C6-alkoxy, C1-C6-halogenalkoxy, C1-C6-alkylthio, C1-C6-halogenalkylthio, NRx1 Rx2, wherein Rx1 and Rx2 independently denote hydrogen, C1-C6-alkyl, or Rx1 and Rx2 together with a nitrogen atom form an N-bonded 5-, 6- or 7-member saturated heteromonocyclic ring or an N-boned 7-, 8-, 9- or 10-member saturated heterobicyclic ring, which are unsubstituted or carry 1, 2, 3 or 4 radicals selected from C1-C4-alkyl. The invention also relates to a pharmaceutical composition based on the compound of formula (I), a method of treatment using the compound of formula (I) and use of the compound of formula (I).
EFFECT: novel quinoline derivatives are obtained, which respond to modulation of the serotonin 5-HT6 receptor.
