, (2008/06/13)
The invention relates to quinazoline derivatives, or pharmaceutically-acceptable salts thereof, which possess anti-tumor activity; to processes for their manufacture; and to pharmaceutical compositions containing them. The invention provides a quinazoline of the formula: STR1 wherein R1 is hydrogen or amino, or alkyl or alkoxy each of up to 6 carbon atoms; or R1 is substituted alkyl or alkoxy each of up to 3 carbon atoms; R2 is hydrogen, alkyl, alkenyl, alkynyl, hydroxyalkyl, halogenoalkyl or cyanoalkyl each of up to 6 carbon atoms; Ar is phenylene or heterocyclene; L is a group of the formula --CO.NH--, --NH.CO--, --CO.NR3 --, --NR3. CO--, --CH=CH--, --CH2 O--, --OCH2, --CH2 S--, --SCH2 --, --CO.CH2 --, --CH2.CO-- or --CO.O--, wherein R3 is alkyl of up to 6 carbon atoms; and Y is aryl or heteroaryl or a hydrogenated derivative thereof: or Y is a group of the formula --A--Y1 in which A is alkylene, cycloalkylene, alkenylene or alkynylene each of up to 6 carbon atoms and Y1 is aryl or heteroaryl or a hydrogenated derivative thereof; or a pharmaceutically-acceptable salt thereof.
