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 --, --CH.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.
本发明涉及公式##STR1##中的烷基氨基和烷基氨基烷基二芳基酮,其中Ar是公式##STR2##中的芳基,其中V是氢,卤素,低烷基,低烷氧基,CF.sub.3,No.sub.2,u是1到3的整数; X和Y独立地是CH.sub.2 --,--CH.sub.2 --或--CHF--; Z和W独立地是--CH.sub.2 --,--O--,--CHOH--或--CHF--; m,n,p,q和t是独立的整数,可以是0或1; 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,适用时还包括其几何和光学异构体和外消旋混合物。本发明的化合物显示出作为镇痛剂和减轻各种记忆功能障碍的作用,其特征是胆碱能功能下降,例如阿尔茨海默病。
