Résumé
7-Hydroxycoumarin (7-HC) is a natural coumarin compound rich in Chinese herbal medicines and has various pharmacological activities. After oral administration of 7-HC in rodents, its conjugated metabolites 7-hydroxycoumarin-β-D-glucuronide (7-HCG) and 7-hydroxycoumarin sulfate (7-HCS), exhibit high systemic exposure and urinary excretion. Organic anion transporters 1 and 3 (OAT1 and OAT3), mainly expressed in the proximal renal tubules, play an important role in drug-drug interactions and drug-induced kidney injury. We aimed to explore the mechanisms of OAT-mediated drug interactions and renal protective mechanisms of 7-HC and its conjugates. OAT-overexpressing cell models revealed that 7-HC was not a substrate for OAT1 and OAT3, while 7-HCG was specifically transported by OAT3. In contrast, 7-HCS can be transported by both OATs. Besides, 7-HC significantly inhibited the activity of OAT1 and OAT3, while 7-HCS had a strong inhibitory effect on OAT1 (IC
