Compounds of the general formula:
(wherein
X represents a halogen atom or a trifluoromethyl group;
R1 and R2 independently represent a hydrogen atom or a lower alkyl group;
Z is -0-, -S-, -SO-, -SO2- or the group -NR4-wherein R4 is as defined for R hereinafter or represents the group COR5 in which R5 represents a hydrogen atom or an optionally substituted aryl, heterocyclic, aralkyl, lower alkyl or lower alkoxy group;
R represents a C6-10 carbocyclic aromatic group or a heterocyclic group containing a 5-9 membered unsaturated or aromatic heterocyclic ring which ring contains one or more heteroatoms selected from 0, N and S and optionally carries a fused ring which carbocyclic or heterocyclic group may carry one or more C1-4 alkyl or phenyl groups, said groups being optionally substituted; or, where Z represents the group >R4, the group -ZR may represent a heterocyclic ring optionally carrying a fused ring and/or optionally substituted as defined for R; and
R3 represents a hydrogen atom or a lower alkyl, lower alkenyl, lower alkynyl, lower alkanoyl, lower alkenoyl, C7-16 aralkyl or C6-10 aryl group or a 5-9 membered unsaturated or aromatic heterocyclic ring); and, where acid or basic groups are present, the salts thereof; are useful in combating abnormal cell proliferation.
The compounds of the invention are prepared by inter alia alkylation, ring closure and oxidation.
