Abstract: Azobarbituric acid derivatives characterized in that in their free acid form they have the following tautomeric structure are disclosed: ##STR1## The azobarbituric acid derivatives are characterized in that X and Y rings can each carry one or two substituents from the series comprising .dbd.O, .dbd.S, .dbd.NR.sub.7, --NR.sub.6 R.sub.7, --OR.sub.6, --SR.sub.6, --COOR.sub.6, --CN, --CONR.sub.6 R.sub.7, --SO.sub.2 R.sub.8, ##STR2## alkyl, cycloalkyl, aryl and aralkyl, the total number of the endocyclic and exocyclic double bonds for each of the rings X and Y being three.The new azobarbituric acid derivatives are other than those of azobarbituric acid, azouracil and uracil-5-azobarbituric acid and their salts. The compounds are useful as pigments which pigments are useful for pigmented paints, in printing inks, distempers or emulsion paints, inter alia.

Abstract: A compound, useful as an anti-cancer drug or agent, having the formulaR.sub.1 --X--R.sub.2where X represents a polynuclear aromatic or heteroaromatic hydrocarbon having between two and four fused rings which may be substituted by hydroxyl, amino, alkylamino, alkoxy or halogeno, R.sub.1 represents: ##STR1## where y represents one member selected from: ##STR2## or alkylated derivatives thereof, and R.sub.2 represents hydrogen or R.sub.1, an acid addition salt of said compound, a nitrogen oxide derivative of said compound in the case where it contains a ring nitrogen atom or atoms, and a quaternary salt of said compound in the case where it contains a ring nitrogen atom or atoms.
