Patent ID: 7655645

Claim:
An indole derivative having the general Formula I wherein A represents a 5-membered aromatic heterocyclic ring, wherein X 1 , X 2 and X 3 are independently selected from N, O, S and CH; Y represents CH 2 , O, S or SO 2 ; R 1 is H, (C 1-4 )alkyl (C 1-4 )alkyloxy, CN or halogen; R 2 , R 2 ′, R 3 , R 3 ′, R 4 , R 4 ′, R 5 and R 5 ′ are independently hydrogen, (C 1-4 )alkyl (optionally substituted with OH) or CO—OR 8 ; or one pair of geminal substituents R 3 and R 3 ′ or R 5 and R 5 ′ together represent a keto group, and the others are all hydrogen or (C 1-4 )alkyl; or R 2 and R 5 together represent a methylene or an ethylene bridge, and R 2 ′, R 3 , R 3 ′, R 4 , R 4 ′ and R 5 ′ are hydrogen; n is 1 or 2; R 6 is H, (C 1-4 )alkyl (optionally substituted with OH, (C 1-4 )alkyloxy, CO—NR 9 R 10 , CO—OR 11 or 1,2,4-oxadiazol-3-yl), SO 2 NR 12 R 13 or COOR 14 ; R 7 is H or halogen; R 8 is (C 1-4 )alkyl; R 9 and R 10 are independently hydrogen, (C 1-4 )alkyl or (C 3-7 )cycloalkyl, the alkyl groups being optionally substituted with OH or (C 1-4 )alkyloxy; R 11 is H or (C 1-4 )alkyl; R 12 and R 13 are independently H or (C 1-4 )alkyl; R 14 is (C 1-6 )alkyl; or a pharmaceutically acceptable salt thereof.
