Abstract
β-Carboline-3-carboxylic acid derivatives of the general formula I <IMAGE> where:- X is an oxygen or sulphur atom, NR10, where R10 denotes a hydrogen atom, or a lower alkyl or cycloalkyl group; R3 is an alkoxy, araloxy or aralkoxy group which is optionally substituted by one or more hydroxyl groups; or NR11R12, where R11 and R12 are identical or different and each denote a hydrogen atom, a hydroxyl group, or an alkyl, aryl, aralkyl or cycloalkyl group which is optionally substituted by a hydroxyl, carboxamide, alkoxycarbonyl or monocyclic group or a heterocyclic group; or an amino group which is optionally substituted by an alkyl, aralkyl, aralkyl or cycloalkyl group; or where R11 and R12, together with the adjacent nitrogen atom, form a 5-, 6- or 7-membered heterocyclic ring; with the proviso, however, that R11 and R12 cannot both be a hydroxyl group; or where X and R3 denote a nitrogen atom; R4 is a hydrogen atom, an alkyl group, a cycloalkyl group, an aralkyl group, or a phenyl or alkoxyphenyl group containing up to 10 carbon atoms, RA is H, F, Cl, Br, I, NO2, NR13R14, NHCOR13, CN, COO R13 or OR13, where R13 and R14 are each a hydrogen atom or an alkyl group which contains up to 6 carbon atoms and is optionally substituted by a hydroxyl group or a halogen atom; SCH3 or SO2NR11R12, where R11 and R12 have the abovementioned meaning, and where each molecule can contain two or more identical or different RA groups; R9 is a hydrogen atom, an alkyl group containing up to 8 carbon atoms, or an alkoxycarbonyl group; with the provisos, however:- that R11 and R12 cannot both denote a hydrogen atom when X denotes an oxygen atom and when R4, RA and R9 each denote a hydrogen atom, that one of the substituents R11 and R12 cannot denote a hydrogen atom when the other substituent denotes an amino group and when X denotes an oxygen atom and R4, RA and R9 each denote a hydrogen atom, and that R4, RA and R9 cannot each denote a hydrogen atom when X denotes an oxygen atom and R3 denotes OCH3.
