Enzymatic continuous-flow preparation of nature-inspired phenolic esters as antiradical and antimicrobial agents

A collection of nature-inspired lipophilic phenolic esters have been prepared by an enzymatic synthesis under flow conditions, using the immobilized lipase B from Candida antarctica (Novozyme 435 (R)) as a catalyst in cyclopentyl methyl ether (CPME), a non-conventional and green solvent. Their antimicrobial activity against four selected bacterial strains together with their efficiency as radical scavengers were evaluated. The obtained compounds were characterized by enhanced lipophilicity in comparison with the parent non-esterified compounds, which increased the possibility of their use as additives in the food industry.

Automated summary

This study synthesized a collection of nature-inspired lipophilic phenolic esters using immobilized lipase in cyclopentyl methyl ether. The obtained compounds showed enhanced lipophilicity compared to the parent non-esterified compounds, making them potential additives in the food industry.
