描述 | Rifampicin is a member of the rifamycin class of antibiotics, as it inhibits bacterial DNA-dependent RNA synthesis (Ki = ~ 1 nM).1 While this compound does not directly affect RNA synthesis in humans, its use as an antibiotic is limited by its potency toward activation of the pregnane X receptor (PXR, EC50 = ~2 µM), which results in the up-regulation of enzymes that alter drug metabolism.2 Access of rifampicin to the nuclear receptor PXR requires its import into the cell via organic anion transporters (OATs) in the OAT polypeptide (OATP) family.3 By acting as a transporter substrate, rifampicin inhibits OATPs with Ki/IC50 values ranging from 0.58-18 µM.4,3,5,6 |
