Feruloyl esterases (FAEs, E.C. 3.1.1.73) are biotechnologically important enzymes with several applications in ferulic acid production from biomass, but also in synthesis of hydroxycinnamic acid derivatives. The use of such biocatalysts in commercial processes can become feasible by their immobilization

The asymmetric total syntheses of (R)-(+)- and (S)-(-)-umbelactone were achieved by using the Sharpless asymmetric epoxidation reaction to generate the stereogenic center and a ring-closing metathesis (RCM) for the formation of the lactone structure. Starting from 3-methyl-2-buten-1-ol, the asymmetric total

Solid-phase organic synthesis of polyprenols with a traceless sulfone linker is described. The polymer-bound benezenesulfinate is first linked with the "tail" building blocks of isoprenyl chlorides via S-alkylation. With use of dimsyl anion as an appropriate base, the polymer-bound alpha-sulfonyl

Ethanol extract of Coccinia grandis (L.) Voigt showed significant triglyceride (TG) and cholesterol-lowering effects in dyslipidemic hamster model. Ethanolic extract was fractionated into chloroform, n-butanol and water-soluble fractions and were evaluated. Activity was proved to be concentrated in chloroform-soluble fraction.
