Abstract: The invention relates to acid addition salts of bases of the formula I <IMAGE> in which A, R1, R2, R3, R4, R5, X and Z have the meanings given in the description, with an acid [PA], which denotes a mono- or polybasic acid selected from carbonic acid, alkanoic acids which are unsubstituted or monosubstituted to polysubstituted, apart from formic acid, unsubstituted acetic acid, lysine and arginine; alkenoic acids which are unsubstituted or substituted, apart from unsubstituted fumaric acid, cycloalkylcarboxylic acids, arylcarboxylic acids, aryl-lower alkylcarboxylic acids in which lower alkyl is unsubstituted or substituted, aryl-lower alkenylcarboxylic acids, heterocyclylcarboxylic acids, alkanesulphonic acids which are unsubstituted or substituted, apart from unsubstituted methanesulphonic acid, aromatic sulphonic acids, alkylsulphuric acids, N-substituted sulphamic acids, organic acids without carboxyl, sulpho, sulphate or phospho groups, and further from pyrophosphoric acid and hydrogen iodide; and tautomers thereof. The acid addition salts are employed for the treatment of disorders which respond to inhibition of S-adenosylmethionine decarboxylase.
