A compound useful as anti-inflammatory agefits in warm- blooded animals of the formula
wherein
X is a member of the class of ethylene and ethenyl and is substituted for hydrogen in the sixth or seventh position of the 1(2H)-phthalazinone ring
Y is a member of the class of hydrogen and hydroxyl
R, is a member of the class of hydrogen, alkyl, alkoxy, hydroxyl, halogen, nitro, -NR3R4, -COR5 and -0-A wherein A is a mineral acid residue which with -0- forms an ester or the alkali metal salt of said ester,
R2 is a member of the class of hydrogen, alkyl, phenyl, substituted phenyl, heteroaryl, hydroxyalkylene, polyhydroxyalkylene, aminoalkylene, alkylaminoalkylene, and carboxyalkylene,
R3, R4, are independently from the class of hydrogen, alkyl, aminoalkylene or alkylaminoalkylene,
R5 is a member of the class of OR3 and
for example hydroxyl, methoxyl, 2-dimethylaminoethoxyl or 2-dimethylaminoethylamino, and wherein by alkyl and alkylene is meant respectively a mono- or divalent saturated aliphatic radical containing up to about eight carbon atoms, wherein the nitrogen of the alkylamino or alkylaminoalkylene may form a heterocycle with the alkyl or alkylene groups, wherein substituted phenyl may be substituted by, for example, alkyl, hydroxyl, alkoxy, halogen, nitro or amino, wherein heteroaryl may be, for example, 2-pyridyl.
