Regioselectivity of phase II metabolism of luteolin and quercetin by UDP-glucuronosyl transferases.
The regioselectivity of phase II conjugation of flavonoids is expected to be of importance for their biological activity. In the present study, the regioselectivity of phase II biotransformation ofExpand

Flavonoid-mediated inhibition of intestinal ABC transporters may affect the oral bioavailability of drugs, food-borne toxic compounds and bioactive ingredients.
The transcellular transport of ingested food ingredients across the intestinal epithelial barrier is an important factor determining bioavailability upon oral intake. This transcellular transport ofExpand

Quantitative structure activity relationship studies on the flavonoid mediated inhibition of multidrug resistance proteins 1 and 2.
In the present study, the effects of a large series of flavonoids on multidrug resistance proteins (MRPs) were studied in MRP1 and MRP2 transfected MDCKII cells. The results were used to define theExpand
