, (2009)
The N-acylation of ethanolamine (2) with various fatty acids 1a-d and esters of fatty acids 1e-h using Candida antarctica B lipase (Novozym 435) are described and optimum conditions for selective N-acylation rather than O-acylation are also discussed. Microwave assisted solution phase, solid supported and conventional methods were investigated and results were compared. There is a synergy between the enzyme catalysis and microwave irradiation.

N-acylethanolamine acid amidase (NAAA) is an N-terminal nucleophile (Ntn) hydrolase that catalyses the intracellular deactivation of the endogenous analgesic and anti-inflammatory agent palmitoylethanolamide (PEA). NAAA inhibitors counteract this process and exert marked therapeutic effects in animal models of pain, inflammation and neurodegeneration. While it is known that NAAA preferentially hydrolyses saturated fatty acid ethanolamides (FAEs), a detailed profile of the relationship between catalytic efficiency and fatty acid-chain length is still lacking. In this report, we combined enzymatic and molecular modelling approaches to determine the effects of acyl chain and polar head modifications on substrate recognition and hydrolysis by NAAA. The results show that, in both saturated and monounsaturated FAEs, the catalytic efficiency is strictly dependent upon fatty acyl chain length, whereas there is a wider tolerance for modifications of the polar heads. This relationship reflects the relative stability of enzyme-substrate complexes in molecular dynamics simulations.

The plant-growth regulators, indole-3-carboxylic acids, were introduced into N-acyl ethanolamines, and a series of N-acyl O-indolylalkyl ethanolamines were prepared. Their biological activities to regulate rape hypocotyl elongation, cucumber cotyledon expansion and common wheat coleoptile growth were tested. The results indicate that the title compounds inhibited rape hypocotyl elongation, especially the indole-3-propionic acid derivatives, whose bioactivity was better than that of indole-3-acetic acid.
