[Contents of furanocoumarins in grapefruit juice and health foods].
Interactions between grapefruit juice and medications have long been recognized. In recent years, several furanocoumarins (FCs) that inhibit P450 activity in intestinal microsomes have been isolated from grapefruit juice. FCs, i.e., bergamottin (BG), bergapten (BP), bergaptol (BT) and 6',7'-dihydroxybergamottin (DHB), in samples was extracted with acetonitrile, and separated on a Phenyl column ...
متن کاملDistribution of furanocoumarins in grapefruit juice fractions.
The reported effects of grapefruit (Citrus paradisi Macf.) juice on oral bioavailability of certain prescription drugs have led to the discovery of the inhibition by compounds in grapefruit of cytochrome P450 3A4 (CYP3A4) in the intestinal wall and liver. Recent evidence indicates that furanocoumarins related to bergamottin [5-[(3',7'-dimethyl-2',6'-octadienyl)oxy]psoralen] are primarily respon...
متن کاملA furanocoumarin-free grapefruit juice establishes furanocoumarins as the mediators of the grapefruit juice-felodipine interaction.
BACKGROUND Grapefruit juice (GFJ) enhances the systemic exposure of numerous CYP3A4 drug substrates, including felodipine, by inhibiting intestinal (but not hepatic) first-pass metabolism. Furanocoumarins have been identified as major CYP3A4 inhibitors contained in the juice, but their contribution to the GFJ effect in vivo remains unclear. OBJECTIVE To ascertain whether furanocoumarins media...

15 صفحه اولRapid Quantitation of Furanocoumarins and Flavonoids in Grapefruit Juice using Ultra-Performance Liquid Chromatography.
INTRODUCTION Grapefruit juice can increase or decrease the systemic exposure of myriad oral medications, leading to untoward effects or reduced efficacy. Furanocoumarins in grapefruit juice have been established as inhibitors of cytochrome P450 3A (CYP3A)-mediated metabolism and P-glycoprotein (P-gp)-mediated efflux, while flavonoids have been implicated as inhibitors of organic anion transport...
