(Bis(substituted methyl)-methyl)-isoquinoline derivatives, process for their preparation and pharmaceutical compositions containing them.

摘要

The subject-matter of the invention are new Äbis(substituted methyl)-methylÜ-isoquinoline derivatives of the formula (I) <CHEM> wherein R<1> and R<2> represent hydroxyl or alkoxy having from 1 to 6 carbon atoms, R<3> is hydrogen, aralkyl having from 1 to 4 carbon atoms in the alkyl moiety or a - @ - R<4> group, in which R<4> is alkyl having from 1 to 5 carbon atoms or phenyl, optionally substituted, preferably by one or more alkyl having from 1 to 4 carbon atoms, alkoxy having from 1 to 4 carbon atoms, halogen and/or nitro, or is -NH-phenyl, X is oxygen or sulfur, R<7> is hydroxyl, halogen or an - O - @ - R<9> group, R<8> is halogen, alkoxy having from 1 to 4 carbon atoms or an - O - @ - R<9> group, in which X has the same meaning as defined above and R<9> independently from R<4> may have the same meanings as defined for R<4>, or is an -NH(C1-4-alkyl) or C3-6-cycloalkyl group, and salts thereof as well as a process for preparing these compounds and pharmaceutical compositions containing them.
