Preventive and/or therapeutic drugs for neuro- degenerative diseases including Alzheimer~s disease, which contain as the active ingredient substances selected from the group consisting of compounds represented by the general formula (I), pharmacologically acceptable salts thereof, and hydrates and solvates of both: (I) wherein A is hydrogen or acetyl; E is 2,5- or 3,5- disubstituted phenyl or an optionally substituted monocyclic or fused - polycyclic heteroaryl group (exclusive of (1) fused-polycyclic heteroaryl whose benzene ring is bonded directly to the -CONH- group, (2) unsubstituted thiazol-2-yl, and (3) unsubstituted benzothiazol-2-yl); and Z is arene which may have a substituent in addition to the groups represented by the general formulae: -O-A (wherein A is as defined above) and -CONH-E (wherein E is as defined above) or heteroarene which may have a substituent in addition to the groups represented by the general formulae: -O-A (wherein A is as defined above) and -CONH-E (wherein E is as defined above).

L'invention concerne des médicaments prophylactiques ou thérapeutiques destinés aux maladies neurodégénératives tels que la maladie d'Alzheimer. Les principes actifs de ces médicaments sont sélectionnés dans le groupe constitué par les composés de la formule générale (I), des sels pharmacologiquement acceptables de ceux-ci, ainsi que des hydrates et des solvates. Dans cette formule, A représente hydrogène ou acétyle, E représente 2,5- ou 3,5-phényle disubstitué ou un groupe hétéroaryle polycyclique monocyclique ou condensé (à l'exclusion de (1) hétéroaryle polycyclique condensé dont le cycle benzénique est directement lié au groupe CONH-, (2) thiazol-2-yl non substitué, et (3) benzothiazol-2-yl non substitué) ; et Z représente arène pouvant avoir un substituant en plus des groupes représentés par la formule générale : O-A (dans laquelle A est tel que défini ci-dessus) et CONH-E (dans laquelle E est tel que défini ci-dessus), ou un hétéroarène pouvant avoir un substituant en plus des groupes représentés par la formule générale : -O-A (dans laquelle A est tel que défini ci-dessus) et CONH-E (dans laquelle E est tel que défini ci-dessus).
