organic anion transporter

Dimesna (BNP-7787) is a synthetic derivative of dithio-ethane sulfonate with uroprotective properties.

Digitoxin (Digitoxinum) is an effective Na+/K+-ATPase inhibitor (EC50 value: 0.78 μM).

Verinurad (RDEA3170) (RDEA3170) is an organic anion transporter URAT1 (SLC22A12) inhibitor for the treatment of gout and hyperuricemia.

Morinidazole shows antibacterial activity and can be used in studies about bacterial infections research such as appendicitis and pelvic inflammatory disease caused by anaerobic bacteria.

Indican (Indoxyl-β-D-glucoside) is a natural protective compound that is used to protect the liver.

SOAT-IN-1 (compound 40) is a potent and selective inhibitor targeting the sodium-dependent organic anion transporter (SOAT), exhibiting IC50 values of 1.6 µM for SOAT and 14.3 µM for NTCP.

Epaminurad (UR-1102) is an orally active, potent, and selective URAT1 (urate transporter 1) inhibitor with a Ki of 0.057 μM, and it inhibits OAT1 and OAT3 (organic anion transporter) modestly. Epaminurad is a uricosuric agent used for research on gout and hyperuricemia [1].

4'-Hydroxy Trazodone, a metabolite of the antidepressant and sedative trazodone, is an inhibitor of organic anion transporter 3 (OAT3; Ki = 16.9 μM) and is selective for OAT3 over OAT1 (Ki > 200 μM).

Estradiol 17-(β-D-glucuronide) (E217G) is an estrogen metabolite formed in the liver and subsequently excreted in bile.1It acts as a substrate of the multidrug resistance protein 2 (MRP2; Km= 75 μM), and through MRP2-mediated transport, functions as a cholestatic agent, decreasing bile flow.1,2In addition to binding to the MRP2 transport site, E217G has been shown to bind to an allosteric site that through positive cooperativity activates its own transportviaMRP2 and the transport of other MRP2 substrates, including the non-cholestatic estrogen metabolite, estradiol 3-(β-D-glucuronide) .2,3E217G has also been reported to be transported by MDR1, MRP1, MRP3, MRP4, MRP7, ABCG2 (a breast cancer resistance protein transporter), and the rat organic anion-transporting polypeptides 1-4.2 1.Loe, D.W., Almquist, K.C., Cole, S.P., et al.ATP-dependent 17β-estradiol 17-(β-D-glucuronide) transport by multidrug resistance protein (MRP).

Indoxyl sulfate-d5 is intended for use as an internal standard for the quantification of indoxyl sulfate by GC- or LC-MS. Indoxyl sulfate is a uremic toxin and a metabolite of tryptophan. It is formed via sulfation of indole, an intermediate generated from tryptophan by intestinal bacteria, by the sulfotransferase (SULT) isoform 1A1 variant 2 (SULT1A1*2) in the liver. Indoxyl sulfate activates the aryl hydrocarbon receptor (AhR) in HepG2 40 6 hepatoma cells (EC50 = 12.1 nM in a reporter assay). It also inhibits the organic anion transporter (OAT) isoforms OAT1 and OAT3 (Kis = 34.2 and 74.4 µM, respectively for the rat transporters) in S2 proximal tubule cells. Indoxyl sulfate (0.2 and 1 mM) increases superoxide anion and nitric oxide levels in isolated human mononuclear blood cells. It increases serum creatinine and blood urea nitrogen (BUN) levels in the 5 6 nephrectomized rat model of chronic renal failure when administered at a dose of 50 mg kg.
