Novel 2,3-benzodiazepine derivatives and pharmaceutical compositions containing the same as the active ingredient

摘要

The invention refers to novel 2,3-benzodiazepine derivatives of formula (I) and pharmaceutical compositions containing the same as the active ingredient. The novel compounds antipasmodic, muscle relaxant and neuroprotective activities. In formula I; X represents a hydrogen atom, a chloro atom or a methoxy group; Y stands for a hydrogen atom or a halo atom; Z means a methyl group or a chloro atom; R is a C_1-4 alkyl group or a group of the formula -NR¹R₂, wherein R¹ and R² represent, independently, a hydrogen atom, a C_1-4 alkyl group, a C_1-4 alkoxy group or a C^3-6 cycloalkyl group.
