The invention relates to a quinoline of the formula:-
wherein each of R¹ and R², which may be the same or different, is hydrogen, halogeno, hydroxy, cyano, carbamoyl, nitro or amino, alkyl, alkoxy, alkylthio, alkylamino, dialkylamino or alkanoylamino each of up to 4 carbon atoms, or substituted alkyl or alkoxy each of up to 3 carbon atoms, provided that both R¹ and R² are not hydrogen;
the quinoline ring may bear further substituents;
R³ is hydrogen or alkyl of up to 4 carbon atoms;
R⁴ is hydrogen, alkyl, alkenyl or alkynyl each of up to 4 carbon atoms or substituted alkyl of up to 3 carbon atoms;
Ar is phenylene, naphthylene or heterocyclene which is unsubstituted or which bears one or more substituents;
R⁵ is such that R⁵-NH₂ is an amino acid;
or a pharmaceutically-acceptable salt or ester thereof.
The compounds possess anti-tumour activity.
