Abstract
BACKGROUND Bupropion (BUP) is widely used as an antidepressant and smoking cessation aid. There are three major pharmacologically active metabolites of BUP, Erythrohydrobupropion (EB), Hydroxybupropion (OHB) and Threohydrobupropion (TB). At present, the mechanisms underlying the overall disposition and systemic clearance of BUP and its metabolites have not been well understood, and the role of transporters has not been studied. OBJECTIVE The goal of this study was to investigate whether BUP and its active metabolites are substrates of the major hepatic uptake and efflux transporters. METHOD CHO or HEK293 cell lines or plasma membrane vesicles that overexpress OATP1B1, OATP1B3, OATP2B1, OATP4A1, OCT1, BCRP, MRP2 or P-gp were used in cellular or vesicle uptake and inhibition assays. Liquid Chromatography-Tandem Mass Spectrometry (LC-MS/MS) was used to quantify transport activity. RESULTS BUP and its major active metabolites were actively transported into the CHO or HEK293 cells overexpressing OATP1B1, OATP1B3 or OATP2B1; however, such cellular active uptake could not be inhibited at all by prototypical inhibitors of any of the OATP transporters. These compounds were not transported by OCT1, BCRP, MRP2 or P-gp either. These results suggest that the major known hepatic transporters likely play a minor role in the overall disposition and systemic clearance of BUP and its active metabolites in humans. We also demonstrated that BUP and its metabolites were not transported by OATP4A1, an uptake transporter on the apical membrane of placental syncytiotrophoblasts, suggesting that OATP4A1 is not responsible for the transfer of BUP and its metabolites from the maternal blood to the fetal compartment across the placental barrier in pregnant women. CONCLUSION BUP and metabolites are not substrates of the major hepatic transporters tested and thus these hepatic transporters likely do not play a role in the overall disposition of the drug. Our results also suggest that caution should be taken when using the model CHO and HEK293 cell lines to evaluate potential roles of transporters in drug disposition.

Abstract
![]()
Hepatocellular
organic anion transporting polypeptides (OATP1B1,
OATP1B3, and OATP2B1) are important for proper liver function and
the regulation of the drug elimination process. Understanding their
roles in different conditions of liver toxicity and cancer requires
an in-depth investigation of hepatic OATP–ligand interactions
and selectivity. However, such studies are impeded by the lack of
crystal structures, the promiscuous nature of these transporters,
and the limited availability of reliable bioactivity data, which are
spread over different data sources in the open domain. To this end,
we integrated ligand bioactivity data for hepatic OATPs from five
open data sources (ChEMBL, the UCSF–FDA TransPortal database,
DrugBank, Metrabase, and IUPHAR) in a semiautomatic KNIME workflow.
Highly curated data sets were analyzed with respect to enriched scaffolds,
and their activity profiles and interesting scaffold series providing
indication for selective, dual-, or pan-inhibitory activity toward
hepatic OATPs could be extracted. In addition, a sequential binary
modeling approach revealed common and distinctive ligand features
for inhibitory activity toward the individual transporters. The workflows
designed for integrating data from open sources, data curation, and
subsequent substructure analyses are freely available and fully adaptable.
The new data sets for inhibitors and substrates of hepatic OATPs as
well as the insights provided by the feature and substructure analyses
will guide future structure-based studies on hepatic OATP–ligand
interactions and selectivity.

Abstract
Steviol glucuronide (SVG) is the major metabolite derived from steviol, the aglycone of stevioside and rebaudioside A. After the ingestion of stevioside and rebaudioside A, SVG is formed and excreted into the urine in humans. In the present study, transporter mediated efflux and uptake of SVG was investigated in order to understand molecular mechanisms underlying its renal clearance. Results showed that SVG was not a substrate of efflux transporters BCRP, MRP2, MATE1 or P-gp. In contrast, OAT3 played a predominant role in the uptake of SVG in comparison to OATP1B1, OATP1B3, or OATP2B1. Quercetin, telmisartan, diclofenac, and mulberrin displayed a relatively strong inhibition against OAT3 mediated uptake of SVG with IC50 values of 1.8, 2.9, 8.0, and 10.0 μM, respectively. Because OAT3 is a major uptake transporter in the kidney, inhibition of OAT3 activity may alter SVG's renal clearance by drugs and natural compounds that are used concomitantly with stevia leaf extracts.
