A pharmaceutical method for improving memory or correcting memory deficiency is disclosed, utilizing compounds having the formula: ##STR1## wherein m and n are zero and one and when m is zero, the dotted line represents a double bond; X is oxygen or sulfur; R.sup.1 and R.sup.2 are hydrogen, loweralkyl, phenyl or phenylloweralkyl, or R.sup.1 and R.sup.2 taken together may form a fused second ring with the nitrogen atoms having three or four methylene groups to which may be attached at any second ring carbon atom thereof, a loweralkyl or phenyl radical; R.sup.3 is hydrogen or loweralkyl; Ar is phenyl, pyridyl, furanyl, thienyl, methoxy-1H-benzotriazolyl, indolinyl, methoxyindolinyl, methoxypyrimidinyl, aminomethoxypyrimidinyl, 1,3-benzodioxolyl or naphthalenyl, the active optical isomers; and the pharmaceutically acceptable acid addition salts thereof.
本发明揭示了一种改善记忆或纠正记忆缺陷的药物方法,利用具有以下式子的化合物:##STR1## 其中m和n为零和一,当m为零时,虚线表示双键;X为氧或硫;R.sup.1和R.sup.2为氢、低碳基、苯基或苯基低碳基,或者R.sup.1和R.sup.2在氮原子上形成一个融合的第二环,该第二环具有三个或四个亚甲基基团,可以连接在任何第二环碳原子上,形成一个低碳基或苯基基团;R.sup.3为氢或低碳基;Ar为苯基、吡啶基、呋喃基、噻吩基、甲氧基-1H-苯并三唑基、吲哚基、甲氧基吲哚基、甲氧基嘧啶基、氨基甲氧基嘧啶基、1,3-苯并二氧杂环基或萘基,其活性光学异构体;以及其药学上可接受的酸盐。
