title: [Hydrolysis by plasma cholinesterase of complex adamantyl-containing esters].
abstract: The kinetics of cholinesterase enzymatic hydrolysis of carboxylic acid adamantyl derivatives was studied in vitro. The maximal rate of enzymatic hydrolysis in the series of bis-esters was shown to increase on elongation of the distance between ester groups. The maximal hydrolysis rate in the series of bis- and mono-esters decreases on elongation of the distance between ester group and quaternary nitrogen atom. The addition of adamantyl radical to the alcohol part of the molecule of bis- and mono-esters prevents the hydrolysis. The addition of lipophilic radicals to the cationic group of derivatives of mono- and dicarboxylic acids exerts a greater effect on the maximal hydrolysis rate in monoesters than in bis-esters.
