A pharmaceutical composition comprising a compound of the following general formula [I] or its salt.
wherein R1 represents aryl or a heteroaromatic group.
R2 represents hydrogen, alkyl, alkenyl, cycloalkyl, cycloalkylalkyl, hydroxyalkyl, haloalkyl, alkoxy, alkylthio, amino, monoalkylamino, dialkylamino, or phenyl. R3 and R4 independently represent hydrogen or alkyl or R3 and R4 taken together with the adjacent N atom represent a 5- through 7-membered cyclic amino group. A represents a single bond C2-10 alkylene. W represents O, S, or (CH2)n (where CH may be substituted by alkyl; n is an integer of 1 or 2). X, Y, and Z may be the same or different and each represents CH (which may be substituted by alkyl), or N. Provided, however, that the case in which X, Y, and Z concurrently represent CH is excluded. The compound of the invention has excellent neuronal death inhibitory activity and is useful as a therapeutic drug for cerebrovascular diseases.
一种药物组合物,包括以下通式[I]的化合物或其盐。其中,R1代表芳基或杂环芳基基团。R2代表氢、烷基、烯基、环烷基、环烷基烷基、羟基烷基、卤代烷基、烷氧基、烷
硫基、
氨基、单烷基
氨基、二烷基
氨基或苯基。R3和R4独立地代表氢或烷基,或者R3和R4与相邻的N原子结合形成5-至7-成员的环状
氨基基团。A代表单键C2-10烷基。W代表O、S或(
CH2)n(其中CH可能被烷基取代;n是1或2的整数)。X、Y和Z可能相同也可能不同,每个代表CH(可能被烷基取代)或N。但是,排除X、Y和Z同时代表CH的情况。该发明的化合物具有出色的神经元死亡抑制活性,可用作治疗脑血管疾病的药物。
