The subject-matter of the invention are new [bis(substituted methyl)-methyl]-isoquinoline derivatives of the formula (I)
wherein
R1 and R2 represent hydroxyl or alkoxy having from 1 to 6 carbon atoms,
R3 is hydrogen, aralkyl having from 1 to 4 carbon atoms in the alkyl moiety or a
group, in which
R4 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,
R7 is hydroxyl, halogen or an
group,
R8 is halogen, alkoxy having from 1 to 4 carbon atoms or an
group, in which
X has the same meaning as defined above and
R9 independently from R4 may have the same meanings as defined for R4, or is an -HH(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.
