The subject matter of the application are new N-substituted (bis(hydroxymethyl)-methyl]-isoquinoline derivatives of the formula (I)
wherein
R' and R2 represent hydroxyl or alkoxy having from 1 to 6 carbon atoms, the dotted line is an optional second bond in the 1,2-position,
R' is alkyl having from 1 to 6 carbon atoms or aralkyl containing from 1 to 4 carbon atoms in the alkyl moiety, or-if there is a single bond in the 1,2-position -further may represent a group of the formula
in which either
X is oxygen and
R4 is alkyl having from 1 to 5 carbon atoms, alkoxy having from 1 to 4 carbon atoms, hydroxyl 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 an -NH2, -NH-C1-4-alkyl, -NH-C3-6-cycloalkyl, -NH-phenyl or -NH-C1-4-alkyl-phenyl group;
or X is sulfur and
R4 is an -NH2, -NH-C1-4-alkyl, -NH-C3-6-cycloslkyl, -NH-phenyl or -NH-C1-4-alkyl-phenyl group; and further
R1 and R1 indepandently stand for hydrogen, alkyl having from 1 to 4 carbon atoms or phenyl, with the proviso that at least one of them is other than phenyl, and salts thereof as well as a process for preparing these compounds and pharmaceutical compositions containing them.
