摘要:
This invention relates to alkylamino and alkyl amino alkyl diarylketones of the formula
where Ar is aryl of the formula where V is hydrogen, halogen, loweralkyl, loweralkoxy, CF₃, NO₂ and u is an integer of 1 to 3; X and Y are independently CH₂-, -CF₂- or -CHF-; Z and W are independently -CH₂-, -O-, -CHOH-, or -CHF-; m, n, p, q and t are integers which are independently 0 or 1; R₁ is H or loweralkyl; R₂ and R₃ 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.
