PURPOSE: An antiamnestic agent of high safety that contains a specific prolinal derivative, thus showing low toxicity. n CONSTITUTION: The objective agent contains, as an active ingredient, an acetyl- prolinal of the formula (A is amino-protecting group in the aminoacid chemistry; X is residual group of aminoacid). The drug has been examined on the passive avoidance in rats and found that it shows markedly high antiamnestic action by intraperitoneal or oral administration. Thus, it is useful as a drug for senile aphronesia. n COPYRIGHT: (C)1985,JPO&Japio |
