The invention relates to quinazoline derivatives, or pharmaceutically-acceptable salts thereof, which possess anti-tumour activity; to processes for their manufacture; and to pharmaceutical compositions containing them.
The invention provides a quinazoline of the formula:-
wherein R¹ includes hydrogen, amino and alkyl or alkoxy each of up to 4 carbon atoms;
R² includes hydrogen, alkyl, hydroxyalkyl and halogenoalkyl each of up to 4 carbon atoms;
R³ is hydrogen or alkyl or up to 3 carbon atoms;
Ar is phenylene or heterocyclene;
L is a group of the formula -CO.NH-, -NH.CO-, -CO.NR⁴-, -NR⁴.CO-, -CH=CH- or -CO.O-, wherein R⁴ is alkyl of up to 4 carbon atoms; and
Y is a branched alkyl group bearing substituents Y² and Y³ the definition of each independently including hydroxy, cyano, aryl and heteroaryl, and the definition of Y³ also optionally including sulpho, N-phenylsulphonylcarbamoyl and 5-tetrazolyl;
or a pharmaceutically-acceptable salt thereof.
