R,S-Sulforaphane

R,S-Sulforaphane is a synthetic version of the naturally occurring compound, R-sulforaphane, from Broccoli. It is a racemic mixture of both the R and S isomers. At room temperature, it is a very slightly yellowish viscous liquid. Its isothiocyanate group reacts with protic solvents such as water and ethanol to form the corresponding thiocarbamates. It reacts with the sulfhydyl group of cysteine and glutathione to form dithiocarbamates (conjugates).Sulforaphane is a Phase II enzyme inducer present in brocolli. It was found to inhibit chemically induced mammary tumor formation in rats.
