| abstract |
The invention relates to the use of cinnoline derivatives of formula (I) n nwherein Z represents —O—, —NH—, —S— or —CH 2 —; m is an integer from 1 to 5; R 1 represents hydrogen, hydroxy, halogeno, nitro, cyano, trifluoromethyl, C 1-3 alkyl, C 1-3 alkoxy, C 1-3 alkylthio or NR 6 R 7 (wherein R 6 and R 7 , which may be the same or different, each represents hydrogen or C 1-3 alkyl); R 2 represents hydrogen, hydroxy, fluoro, chloro, methoxy, amino or nitro; R 3 represents hydroxy, halogeno, C 1-3 alkyl, C 1-3 alkoxy, C 1-3 alkanoyloxy, trifluoromethyl, cyano, amino or nitro; R 4 represents hydrogen, hydroxy, halogeno, cyano, nitro, amino, trifluoromethyl, C 1-3 alkyl or a group R 5 —X 1 (wherein X 1 represents —O—, —CH 2 —, —S—, —SO—, —SO 2 —, —NR 8 CO—, —CONR 9− , —SO 2 NR 10 —, —NR 11 SO 2 — or —NR 12 — (wherein R 8 , R 9 , R 10 , R 11 and R 12 each independently represents hydrogen, C 1-3 alkyl or C 1-3 alkoxy C 2-3 alkyl) and R 5 is an optionally substituted alkyl, carbocylic or heterocylic group which may be saturated or unsaturated and may be directly linked to the cinnoline ring or be linked via a carbon chain which may have heteroatom linking groups within it and salts thereof, in the manufacture of a medicament for use in the production of an antiangiogenic and/or vascular permeability reducing effect in a warm-blooded animal such as a human being, processes for the preparation of such derivatives, pharmaceutical compositions containing a compound of formula (I) or a pharmaceutically acceptable salt thereof as active ingredient and compounds of formula (I). 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. |
