6',7'-Dihydroxybergamottin (DHB) is a key furanocoumarin responsible for grapefruit juice's drug interaction effects, acting as a potent and selective mechanism-based inhibitor of CYP3A4. It is extensively used in pharmacological research for in vitro and in vivo studies of cytochrome P450-mediated metabolism and drug-drug interactions.
