Objective: The objective of the study was to investigate whether bupropion (BUP) or its circulation metabolites could decrease plasma level of asymmetric dimethylarginine (ADMA) and ameliorate renal injury by modulation of Ddah1, Oatp4c1, Oct2, and Mate1 in rats with adenine-induced chronic renal injury.Methods: The study initially determined the effect of BUP and its metabolites on cell viability and apoptosis in HK2 cells in the presence and absence of ADMA. Secondly, the study explored whether long-term administration of BUP could reduce the plasma level of ADMA and mitigate renal damage. Thirdly, the expression and activity of Oct2, Ddah1, Mate1 and Oatp4c1 was determined by Western blot and UPLC-MS/MS.Results: With 0.5 μmol/L ADMA, hydroxybupropion (HBUP, 100 nmol/L), threo-hydrobupropion (TBUP, 10 nmol/L and 1 μmol/L) reduced N-Acetyl-β-D-glucosidase (NAG) level. At 5 μmol/L ADMA, BUP (1 nmol/L-1 μmol/L), HBUP (1–100 nmol/L), and BUP cocktail enhanced survival. At 50 μmol/L ADMA, HBUP (10 nmol/L and 1 μmol/L), TBUP/erythro-hydrobupropion (EBUP) (10–100 nmol/L), and BUP cocktail stimulated survival. EBUP (1 and 100 nmol/L) lowered LDH. BUP (100 nmol/L) and TBUP (1 μmol/L) decreased NAG. TBUP (10 nmol/L, 1 μmol/L) and EBUP (100 nmol/L) inhibited apoptosis. In adenine-induced chronic renal injury rats, long-term administration of BUP significantly decreased the serum concentration of ADMA and creatinine by 12.78% and 38.85%, respectively, ameliorated interstitial lesions and fibrosis and upregulated Ddah1, Oatp4c1, Oct2, Mate1. BUP increased metformin renal clearance without affecting digoxin disposition.Conclusion: Bupropion moderately decreases plasma levels of ADMA and ameliorates renal injury by modulation of Ddah1, Oatp4c1, Oct2, and Mate1.

Entecavir (ETV) is a first-line antiviral agent for the treatment of chronic hepatitis B virus infection. Renal excretion is the major elimination path of ETV, in which tubular secretion plays the key role. However, the secretion mechanism has not been clarified. We speculated that renal transporters mediated the secretion of ETV. Therefore, the aim of our study was to elucidate which transporters contribute to the renal disposition of ETV. Our results revealed that ETV (50 μM) remarkably reduced the accumulation of probe substrates in MDCK cells stably expressing human multidrug and toxin efflux extrusion proteins (hMATE1/2-K), organic cation transporter 2 (hOCT2), and carnitine/organic cation transporters (hOCTNs) and increased the substrate accumulation in cells transfected with multidrug resistance-associated protein 2 (hMRP2) or multidrug resistance protein 1 (hMDR1). Moreover, ETV was proved to be a substrate of the above-described transporters. In transwell studies, the transport of ETV in MDCK-hOCT2-hMATE1 showed a distinct directionality from BL (hOCT2) to AP (hMATE1), and the cellular accumulation of ETV in cells expressing hMATE1 was dramatically lower than that of the mock-treated cells. The accumulation of ETV in mouse primary renal tubular cells was obviously affected by inhibitors of organic anion transporter 1/3 (Oat1/3), Oct2, Octn1/2, and Mrp2. Therefore, the renal uptake of ETV is likely mediated by OAT1/3 and OCT2 while the efflux is mediated by MATEs, MDR1, and MRP2, and OCTN1/2 may participate in both renal secretion and reabsorption.

Sulpiride, a selective dopamine D2 receptor blocker, is used widely for the treatment of schizophrenia, depression and gastric/duodenal ulcers. Because the great majority of sulpiride is positively charged at physiological pH 7.4, and ~70% of the dose recovered in urine is in the unchanged form after human intravenous administration of sulpiride, it is believed that transporters play an important role in the renal excretion of sulpiride. The aim of the present study was to explore which transporters contribute to the renal disposition of sulpiride. The results demonstrated that sulpiride was a substrate of human carnitine/organic cation transporter 1 (hOCTN1) and 2 (hOCTN2), human organic cation transporter 2 (hOCT2), human multidrug and toxin efflux extrusion protein 1 (hMATE1) and 2-K (hMATE2-K). Sulpiride accumulation from the basolateral (BL) to the apical (AP) side in MDCK-hOCT2/pcDNA3.1 cell monolayers was much greater than that in MDCK-hOCT2/hMATE1 cells, and cimetidine dramatically reduced the intracellular accumulation of sulpiride from BL to AP. In addition, the accumulation of sulpiride in mouse primary renal tubular cells ( m PRTCs) was markedly reduced by inhibitors of Oct2 and Octns. The results implied that OCTN1, OCTN2, OCT2, MATE1 and MATE2-K probably contributed to the renal transfer of sulpiride, in which OCT2 mediated the uptake of sulpiride from the bloodstream to the proximal tubular cells, while MATEs contributed to the sulpiride efflux from the proximal tubular cells to the renal lumen, and OCTNs participated in both renal secretion and reabsorption.
