| abstract |
The invention relates to compounds of the formula (I): wherein: ring C is 9 or 10-membered bicyclic heteroaromatic group containing at least one nitrogen atom in the ring attached to Z and optionally containing a further 1-3 heteroatoms, selected independently from O, S, and N, with the proviso that ring C is not a quinazoline, quinoline or cinnoline group; either any one of G 1 , G 2 , G 3 , G 4 and G 5 is nitrogen and the other four are —CH—; or G 1 , G 2 , G 3 , G 4 and G 5 are all —CH—; Z is —O—, NH—, —S—, CH 2 — or a direct substituents R 1 may be attached at any free carbon atom of the indole, azaindole or indazole group; m is an integer from 0 to 2; R b represents hydrogen or another value as defined herein; R 1 represents hydrogen, hydroxy, halogeno, C 1-4 alkyl, or any other value as defined herein; R 2 represents hydrogen, hydroxy, halogeno, cyano, nitro, trifluoromethyl, C 1-3 alkyl, C 1-3 alkoxy, C 1-3 alkylsulphanyl, —NR 3 R 4 (wherein R 3 and R 4 , which may be the same or different, each represents hydrogen or C 1-3 alkyl), or R 5 X 1 — (wherein R 5 and X 1 are as defined herein) and salts thereof, processes for the preparation of such compounds, pharmaceutical compositions |
