A-type carboxylic ester hydrolases (arylesterases EC 3.1.1.2), which hydrolyse aromatic esters, e.g. phenylacetate they show little activity on tributyrin, and are not inhibited by organophosphates.

In a modified version of the pharmacophore point filter, a score equal to 1 is allowed to qualify a compound as drug-like if the pharmacophore point present in the compound is of type carboxylic acid, amine, guanidine, or amidine. This modified filter was defined to correctly classify the small active drugs belonging to the central nervous system (CNS) class.

In conclusion, IR evidence indicates that tin(IV) reached five coordination in RjSnClantibiotic nH O coordinating lactamic C=0 and the oxygen atom of the ester type carboxylic group, R SnClantibioticNa nH O through the coordination of only the lactamic C=0. 

Yeung et al. introduced new Cinchona amino-thiocarbamate catalysts 6 and 7 for bromolactonisation of unsaturated carbo>ylic acids,and styrene-type carboxylic acids that were successfully converted to y- and 8-lactones (Scheme 15.40).

Serine hydrolases hydrolases which have a cata-lytically active serine residue in their active center, e. g. trypsin, chymotrypsin A, B and C, thrombin and B-type carboxylic acid esterases. See Serine proteases. 

The RTV condensation ciue system consists of four types carboxylate cure, alk-oxide cure, oxime cure, and amine cure. For electronic applications, only the alkoxide cure system is preferred because the byproduct alcohol generated during cure is non-corrosive. 

At greater oxidant dosages, toxicity was largely due to intermediate-type carboxylic acids, but below 5 mol of H2O2 per mol of phenol, aromatic-type compounds were mainly responsible for toxicity, where the increase of catalyst concentration had a negative effect.
