Abstract

Compounds of general formula:- and their salts, in which one or more of the residues R1-R4 indicate amino groups, which can be acylated and alkylated by alkyl residues; those of the residues R1-R4 which are not amino groups, indicate hydrogen halogen low-molecular alkyl trifluoromethyl cyano sulphocyano (rhodano) mercapto, low-molecular alkylsulpho, acyl-sulpho hydroxy, low-molecular, alkoxy, methylenedioxy, acyloxy nitro carboxy, carbalkoxy or cabamoyl R5 stands for a hydrogen or an acyl residue; R6 stands for a hydrogen a low-molecular alkyl or an unbranched phenalkyl; X signifies a nitrogen or the CH-group; and wit the abovementioned acyl residues being derviced from carbonic acid, from carbonic acid half-morpholide, from carbonic acid monoesters, from preferably substituted benzoic acids and pyridine-carboxylic acids, or from saturated or unsaturated low-molecular aliphatic mono-or dicarboxylic acids, which can be substituted by a morpholine residue.
