The present invention relates to 5-aminoalkyl and 5-aminocarbonyl substituted indole derivatives having general formula (I), wherein R1 is-(CH¿2?)n-1-CONR?10R11¿, -(CH¿2?)n-NR?10R11¿ or (a), wherein R?10 and R11¿ independently are selected from hydrogen, C¿1-6?-alkyl, C2-6-alkenyl, C2-6-alkynyl, C3-8-cycloalkyl, C3-8-cycloalkyl-C1-6-alkyl, aryl-C1-6-alkyl, aryl, acyl, amino-C1-6-alkyl and mono- or di-C1-6-alkylamino-C1-6-alkyl, R?12¿ is hydrogen, or C¿1-6?-alkyl n is 1 to 3 and q is 2 to 5; G is N, C, or CH; the dotted line meaning a bond when G is C, and the dotted line meaning no bond when G is CH, or N; Ar is phenyl optionally substituted with one or more substituents independently selected from halogen, C1-6-alkyl, C1-6-alkoxy, hydroxy, trifluoromethyl and cyano, or Ar is 2-thienyl, 3-thienyl, 2-furanyl, 3-furanyl, 2-thiazolyl, 2-oxazolyl, 2-imidazolyl, 2-pyridyl, 3-pyridyl, or 4-pyridyl; R?2, R3, R4 and R5¿ are independently selected from hydrogen, C¿1-6?-alkyl, C1-6-alkoxy, hydroxy, halogen, trifluoromethyl, nitro, cyano, amino, C1-6-alkylamino and C1-6-dialkylamino; R?6¿ is hydrogen, or C¿3-8?-cycloalkyl, C3-8-cycloalkyl-C1-6-alkyl, C1-6-alkyl, C2-6-alkenyl or C2-6-alkenyl, which may optionally be substituted with one or two hydroxy groups, any hydroxy group present being optionally esterified with an aliphatic carboxylic acid having from two to twentyfour carbon atoms inclusive, or R?6¿ is a group of Formula (II) or (III): wherein m is an integer from 2-6; W is O, or S; U is N or CH; Z is -(CH¿2?)p-, p being 2 or 3, or Z is -CH=CH- or 1,2-phenylene optionally substituted with halogen or trifluoromethyl, or Z is -COCH2- or -CSCH2-; V is O, S, CH2, or NR?9¿ wherein R9 is hydrogen, or C¿1-6?-alkyl, C2-6-alkenyl or C2-6-alkenyl, which may optionally be substituted with one or two hydroxy groups, or a C3-8-cycloalkyl or C3-8-cycloalkyl-C1-6-alkyl group; X is N, C, or CH; Y is N, C, or CH; provided at least one of X and Y is N; and R?7¿ is hydrogen, or C¿1-6?-alkyl; or a pharmaceutically acceptable acid addition salt thereof. The novel 5-aminoalkyl and 5-aminocarbonyl substituted indoles have high affinity for α1-adrenoceptors and are considered useful for the treatment of diseases or disorders responsive to α1-adrenoceptor antagonists. Further, as the compounds are selective α1-adrenoceptor ligands they may be particularly useful as PET or SPECT ligands.
