Sulfation modulates the cell uptake, antiradical activity and biological effects of flavonoids in vitro: An examination of quercetin, isoquercitrin and taxifolin

Original language description

This study was designed to prepare quercetin 3'-O-sulfate (1), isoquercitrin 4'-O-sulfate (2) and taxifolin 4'-O-sulfate (3) by the sulfation of quercetin, isoquercitrin and taxifolin using arylsulfate sulfotransferase from Desulfitobacterium hafniense,and to examine effect of sulfation on selected biological properties of the flavonoids. Flavonoid sulfates 1-3 were weaker DPPH radical scavengers than the corresponding nonsulfated flavonoids, and 1-3, unlike quercetin, did not induce the expression ofeither heme oxygenase-1 in RAW264.7 cells or cytochrome P450 1A1 in HepG2 cells. The cell uptake of 1-3 was much lower than that of quercetin, but comparable to that of the glycoside isoquercitrin. Moreover, HPLC/MS metabolic profiling in HepG2 cells showed that flavonoid sulfates 1-3 were metabolized to a limited extent compared to the nonsulfated compounds.
