The invention relates to compounds of the formula I: wherein: ring C is a 5 or 6-membered heteroaromatic ring containing at least one nitrogen atom and optionally containing a further 1-2 heteroatoms, selected independently from O, S and N; either any one of G1, G2, G3, G4 and G5 is nitrogen and the other four are -CH-, or G1, G2, G3, G4, and G5 are all - CH-; Z is -O-, -NH-, -S-, CH2-, or a direct bond; Z is linked to any one of G1, G2, G3, and G4; n is an integer from 0 to 5; any of the substituents R1 may be attached at any free carbon atom of the indole, azaindole or indazole group; m is an integer from 0 to 4, Rb represents hydrogen or another value as defined herein; R1 represents hydrogen, oxo, hydroxy, halogeno, C¿1-4?alkyl, C1-4alkoxy, C1-4alkyxyC1-4alkyl, aminoC1-4alkyl, aminoC1-4alkyl, C1-3alkylaminoC1-4alkyl, di(C1-3alkyl)aminoC1-4alkyl, -C1-5alkyl(ring B) wherein ring B is selected from azetidinyl, pyrrolidinyl, piperidinyl, piperazinyl, N-methylpiperzinyl, N-ethylpiperazinyl, morpholino and thiomorpholino; R?2¿ represents hydrogen, hydroxy, halogeno, cyano, nitro, trifuloromethyl, C ¿1-3?alkyl, C1-3alkoxy, C1-3alkylsulphanyl,-NR?3R4¿ /wherein R?3 and R4¿, which may be the same or different, each represents hydrogen or C¿1-3?alkyl), or R?5X1¿-(wherein R?5 and X1¿ are as defined herein) and salts thereof, processes for the preparation of such compounds, pharmaceutical compositions containing a compound of formula I or a pharmaceutically acceptable salt thereof as active ingredient and the use of compound of formula I in the manufacture of a medicament for the production of an antiangiogenic and/or vascular permeability reducing effect in warm-blooded animals. The compounds of formula I and the pharmaceutically acceptable slats thereof inhibit the effects of VEGF, a property of value in the treatment of a number of disease states including cancer and rheumatoid arthritis.
