Synthesis and preliminary pharmacological activity of aminoalkoxy isosteres of glycolate ester anticholinergics.

A sides of 2-(N-substituted amino)alkoxy-1,1-diphenylethanols was synthesized and evaluated for anticholinergic activity. The compounds differ structurally from the glycolate ester-type anticholinergic compounds by the bioisosteric substitution of a methylene group for the ester carbonyl moiety. The ethers which result from this change have increased lipophilicity compared to their ability to inhibit perphenazine-induced catatonia in rats. Structure-activity relationships of the compounds are discussed.
