| abstract |
The invention relatest to compounds of the formula (I) wherein 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 which is a free carbon atom; n is an integer from 0 to 5; any of the substitutents R1 may be attached at any free carbon atom of the indole, azaindole or indazole group; m is an integer from 0 to 3; Ra represents hydrogen; Rb represents hydrogen or another value as defined herien; R1 represents hydrogen, oxo, hydroxy, halogeno, C¿1-4?alkyl, C1-4alkoxy, C1-4alkoxyC1-4alkyl, 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-methylpiperazinly, N-ethylpiperazinyl, morpholino and thiomorpholino; R?2¿ represents hydrogen, hydroxy, halogeno, cyano, nitro, trifluoromethyl, C¿1-3?alkyl, C1-3alkoxy, C1-3aklylsulphanyl, -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 a compound of formula I in the manufacture of 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 salts thereof inhibit the effects of VEGF, a property of value in the treatment of a number of disease states including cancer and rheumatoid arthritis. |
