  The invention relates to new 2,3-benzodiazepine derivatives of general Formula (I), (wherein R1 stands for methyl, formyl, carboxy, cyano, —CH═NOH, —CH═NNHCONH2 or —NR5R6, wherein R5 and R6 independently from each other represent hydrogen or lower alkyl or together with the nitrogen atom, they are attached to, form a 5- or 6-membered, saturated or unsaturated heterocyclic ring optionally containing one or more further nitrogen, sulfur and/or oxygen atom(s); R2 is nitro or amino; R3 stands for hydrogen, lower alkanoyl or CO—NR7R8, wherein R7 and R8 independently from each other stand for hydrogen, lower alkoxy, lower alkyl or lower cycloalkyl or together with the nitrogen atom, they are attached to, form a 5- or 6-membered, saturated or unsaturated heterocyclic ring optionally containing one or more further nitrogen, sulfur and/or oxygen atom(s); R4 is hydrogen or lower alkyl; the dotted lines have the following meaning: if R3 and R4 are not present, the bond between positions C8 and C9 is a single bond and the bond between positions C8 and N7 is a double bond; if R3 and R4 are present, the bonds between positions C8 and C9 and between position C8 and N7 are single bonds; and if R3 is present and R4 is missing, the bond between positions C8 and C9 is a double bond and the bond between positions C8 and N7 is a single bond) and salts thereof. The invention compounds have neuroprotective effect.

  本发明涉及一种新的2,3-苯二氮平衍生物，其一般式为（I），其中R1代表甲基，甲酰基，羧基，氰基，—CH═NOH，—CH═NNHCONH2或—NR5R6，其中R5和R6独立地代表氢或较低的烷基，或者与氮原子结合形成一个5或6成员的饱和或不饱和的杂环环，可选地含有一个或多个进一步的氮、硫和/或氧原子；R2为硝基或氨基；R3代表氢，较低的烷酰基或CO—NR7R8，其中R7和R8独立地代表氢，较低的烷氧基，较低的烷基或较低的环烷基，或者与氮原子结合形成一个5或6成员的饱和或不饱和的杂环环，可选地含有一个或多个进一步的氮、硫和/或氧原子；R4为氢或较低的烷基；虚线具有以下含义：如果R3和R4不存在，则C8和C9位置之间的键为单键，C8和N7位置之间的键为双键；如果R3和R4存在，则C8和C9位置之间的键和C8和N7位置之间的键均为单键；如果R3存在且R4不存在，则C8和C9位置之间的键为双键，C8和N7位置之间的键为单键。本发明化合物具有神经保护作用。
