Natural dihydrocoumarin, which is of great interest in the flavor industry, was biotechnologically produced from pure coumarin or tonka bean meal with Pseudomonas orientalis, Bacillus cereus, and various Saccharomyces cerevisiae strains. Coumarin was shown to be converted to melilotic acid

The first dual activatable hypochlorite ((-)OCl)-sensing probe was developed, based on a new proof-of-concept design involving signal-activatable (1)H chemical probes using the triple-resonance NMR technique. The probe enabled fluorescence-(1)H MR dual turn-on detection of (-)OCl in solution and in crude

Afri et al. reported in this journal (Free Radic. Biol. Med.32:605-618; 2002) that a direct relationship exists between the depth of alkanoylcoumarins 1 within the liposomal lipid bilayer and the rate at which they undergo superoxide-mediated saponification. These results were
The flavoring agent dihydrocoumarin reverses epigenetic silencing and inhibits sirtuin deacetylases.
Andrew J Olaharski et al.
PLoS genetics, 1(6), e77-e77 (2005-12-20)
Sirtuins are a family of phylogenetically conserved nicotinamide adenine dinucleotide-dependent deacetylases that have a firmly established role in aging. Using a simple Saccharomyces cerevisiae yeast heterochromatic derepression assay, we tested a number of environmental chemicals to address the possibility that

A series of new 3-methylidenechroman-2-ones bearing various aromatic moieties and various substituents at position 4 were synthesized in a three step reaction sequence. Friedel-Crafts alkylation of phenols or naphthols using ethyl 3-methoxy-2-diethoxyphosphorylacrylate in the presence of trifluoromethanesulphonic acid gave 3-diethoxyphosphorylchromen-2-ones.
