The substrate specificity of carboxylesterases (CEs) in various respiratory tract tissues from F344/N-rats, New-Zealand-white-rabbits, and Syrian-hamsters was studied using ion chromatography to quantify hydrolysis rates. Thirteen esters were tested: pentyl-acetate, phenyl-acetate and beta-butyrolactone were used for interspecies comparison. Liver S9 had the most catalytic activity in rats whereas in rabbits and hamsters the values for trachea and nasal S9 were as active or more active than liver for all substrates tested except pentyl-acetate. Lung S9 showed reduced esterase activity relative to the other tissues. ... Straight chain alcohol esters were the most rapidly hydrolyzed and tertiary esters had the slowest hydrolysis rate. ...
The substrate specificity for carboxylic acid esters was determined for phosphoric triester hydrolases and serine esterases. Serum was obtained from 452 individuals, including non diseased person and patients with hyperlipemia. Correlations between enzyme activities, reversible inhibition by EDTA and progressive inhibition by organophosphate compounds and carbamates were made. The hydrolysis of paraoxon (POX), phenylacetate (PA), and beta-naphthylacetate (BNA) was studied. Results indicated that two paraoxonases hydrolyze paraoxon, one sensitive and the other insensitive to EDTA. The EDTA sensitive paraoxonase also hydrolyzed beta-naphthylacetate. The EDTA insensitive hydrolysis of beta-naphthylacetate and phenylacetate was assigned to a serine esterase. The EDTA sensitive hydrolysis of phenylacetate was likely due to more than one enzyme, which may be an arylesterase and a carboxylesterase.

The effects of phenylacetate (PA) on fetal brain growth were examined in pregnant rats receiving a 20% casein diet with 1.0, 1.5, 2.0, or 2.5% phenylacetate. Control rats were fed the 20% casein diet ad libitum or restricted to daily consumption of 9 and 6 g. In experimental groups of rats total food intake during pregnancy decreased. ... By plotting the fetal brain weight (Y, mg) against maternal food intake (X, g/21 days) in control groups /an/ hyperbolic regression equation was obtained. ... Similar plots for excess phenylacetate rats fell below this line, indicating that prenatal fetal brain growth was impaired by an excess in phenylacetate per se specifically, as well as by decreased food intake nonspecifically. Administering the excess phenylacetate diets resulted in decreases in total RNA, total protein and RNA/DNA ration in the fetal brain, whereas total DNA was unchanged, showing the impairment of protein synthesis, not proliferation. No remarkable changes in concentration and pattern of free amino acids in maternal plasma in excess phenylacetate groups were observed. ...

An efficient and convenient protocol has been developed for ether bondformation in mild conditions. A mixture of primary/secondary ester and allylic/benzylic halide in tetrahydrofuran was treated with KOtBu at room temperature to give ether in high yield. This step economic method enabled direct alkylation of the acyl group masked O-nucleophiles. Application of this method in carbohydrate synthesis
