3,4-Dihydrocoumarins, considered to be valuable building blocks, have attracted considerable attention due to their various biological activities. Herein, we have documented an efficient and convenient double decarboxylation process for the synthesis of 4-substituted 3,4-dihydrocoumarin in moderate to excellent yields under

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

Further confirmation of the effects of vehicles and elicitation concentration in experimental contact sensitization testing with fragrance ingredients is reported. A dose-response relation was seen when sensitized human subjects were challenged with dihydrocoumarin, alantroot oil and diethylmalleate. Furthermore, alcohol was
