This invention relates to alkylamino and alkyl amino alkyl diarylketones of the formula ##STR1## where Ar is aryl of the formula ##STR2## where V is hydrogen, halogen, loweralkyl, loweralkoxy, CF.sub.3, NO.sub.2 and u is an integer of 1 to 3; X and Y are independently CH.sub.2 --, --CF.sub.2 -- or --CHF--; Z and W are independently --CH.sub.2 --, --O--, --CHOH--, or --CHF--; m, n, p, q and t are integers which are independently 0 or 1, R.sub.1 is H or loweralkyl; R.sub.2 and R.sub.3 are loweralkyl; and the pharmaceutically acceptable acid addition salts thereof and where applicable the geometric and optical isomers and racemic mixtures thereof. The compounds of this invention display utility as analgesic agents and as agents for alleviating various memory dysfunctions, characterized by a decreased cholinergic function, such as Alzheimer's disease.
本发明涉及以下化学式的烷基氨基和烷基氨基烷二芳基酮:##STR1## 其中Ar是化学式##STR2##的芳基,其中V是氢、卤素、低烷基、低烷氧基、CF.sub.3、NO.sub.2,u是1至3的整数;X和Y分别是CH.sub.2 --、--CF.sub.2 --或--CHF--;Z和W分别是--CH.sub.2 --、--O--、--CHOH--或--CHF--;m、n、p、q和t是独立的0或1的整数,R.sub.1是H或低烷基;R.sub.2和R.sub.3是低烷基;以及其药学上可接受的酸加成盐,如适用,其几何和光学异构体和外消旋混合物。本发明的化合物具有镇痛剂和缓解各种记忆功能障碍的用途,其特征是胆碱能功能降低,例如阿尔茨海默病。
