Zusammenfassung: | 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. |
