PREVIOUS work on acid-catalysed amide hydrolysis has indicated that the reaction is bimolecular: in the rate-determining step the conjugate acid of the amide is attacked by a water molecule. This conclusion is derived from three types of evidence. It has been shown that in concentrated aqueous ...
The greater reactivity of esters relative to amides has typically been reflected in their faster rates of both solvolysis and enzymatic hydrolysis. In contrast to this general principle, the serine hydrolytic enzyme fatty acid amide hydrolase (FAAH) was found to degrade amides and esters with equival...
Pre-incubation studies showed significant differences in the FAAH inhibitory activity of N -benzyloctadeca-9Z,12Z-dienamide, N- benzyloleamide, and N -benzylstearamide, indicating that the inhibitory mechanism of these compounds is time-dependent. Incubation of N -benzyloctadeca-9Z,12Z-dienamide ...
This is the most useful method of amide formation (equation2). An activatedcarboxylic acidacylates ammonia, primary or secondary amines by a formalSN2 substitution of leaving group X. The reactivity of the acylating reagent depends on the acidity of HX, and therefore the order of reactivity is...
Our study focuses on two candidate systems that may contribute to the resistance to AEA: (i) the AEA degrading enzyme fatty acid amide hydrolase (FAAH), which is highly expressed and active in the liver and represents the main mechanism that determines the biological half-life of AEA (24, ...

258–265 Comparison of the active site features of these eukaryotic HDACs and the histone deacetylase-like proteins (HDLPs) indicates a conserved set of active site amino acid residues, suggesting that the hydrolysis reactions catalyzed by these enzymes likely share a common mechanism. The active ...
