The present patent application discloses compounds of the formula
wherein
R¹ is C₁₋₁₀-alkyl which may be branched; C₁₋₁₀-unsaturated alkyl; or CHR'''
wherein R''' is H or
R² is phenyl which may be substituted one or more times with halogen, CF₃, C₁₋₆-alkoxy, NO₂, CO₂-C₁₋₆-alkyl, methyl; benzyl which may be substituted one or more times with halogen, CF₃, C₁₋₆-alkoxy, NO₂, CO₂-C₁₋₆-alkyl, methyl; pyridyl; or cyclohexyl;
R³ phenyl which may be substituted one or more times with halogen, CF₃, C₁₋₆-alkoxy, NO₂, CO₂-C₁₋₆-alkyl, methyl; naphthyl which may be substituted one or more times with halogen, CF₃, C₁₋₆-alkoxy, NO₂, CO₂-C₁₋₆-alkyl, methyl; pyridyl; C₁₋₆ unsaturated alkyl; furanyl;
R⁴ is H, C₁₋₆-alkyl, or benzyl;
or
together form
R⁵ is H, or C₁₋₆-alkyl;
R' and R'' are each hydrogen or together form an extra benzo ring;
and wherein the dotted line represents an optional extra bond between the two carbon atoms designated α and β, or a pharmaceutically-acceptable addition salt thereof.
The compounds are useful as pharmaceuticals, for example in the treatment of Ca overload in brain cells.
