| abstract |
Abstract 1-(3-Hydxoxy-4-methoxybenzoyl)-3-hydroxy-2-pyrrol--idinone of the formula I is suitable for use in the control or prevention of cerebral insufficiency or in the improvement of intellectual capacity. This compound contains an asymmetric carbon atom; not only the two optically uniform enantiomeric forms but also the racemate are described. The compound of formula I can be manufactured by cleaving off the protecting group (5) from a corresponding compound in which at least one of the two hydroxy groups is protected. It can be administered in galenical administration forms. |
