Hepatic organic anion transporters oatp1b1 and oatp1b3 are expressed at the sinusoidal membrane of hepatocytes and contribute to the hepatic uptake of a wide variety of clinically used drugs to identify the antibiotics that interact with the human organic anion transporters oatp1b1 and oatp1b3, we. Protein-based drug transporters are found in most tissues including liver, kidney, intestine, and brain because of their complexity and genetic heterogeneity, these proteins are often produced as recombinant membrane.

Interaction of ethambutol with human organic cation transporters (slc22 family) indicates potential for drug-drug interactions during antituberculosis therapy. Abstract abstract renal excretion of organic anions and cations is mediated by the organic ion transporter family (slc22a) in this study, the mrna levels of the organic ion transporters were quantified by real-time pcr in normal parts of renal tissues from seven nephrectomized patients with renal cell carcinoma, and the distributions and. Recent advances in molecular biology have identified three organic anion transporter families: the organic anion transporter (oat) family encoded by slc22a, the organic anion transporting peptide (oatp) family encoded by slc21a (slco), and the multidrug resistance-associated protein (mrp) family encoded by abcc.

Organic anion transport polypeptide c an organic anion transporter found in human liver it is capable of transporting a variety organic anions and mediates sodium-independent uptake of bile in the liver.

Membrane transporters play critical roles in moving a myriad of endogenous and exogenous substances across cellular and organelle membranes, including the major nutrient metabolites sugars, digested peptides, amino acids and nucleosides, rare elements such as hormones and neurotransmitters, and xenobiotics. Since the substrate specificities of oatp1b1, 1b3, and 2b1 are broad and overlapping, the contribution of each isoform to the overall hepatic uptake is of concern when assessing transporter-mediated drug–drug interactions (ddis) or genetic polymorphism impact in the clinic. Nucleoside reverse transcriptase inhibitors (nrtis) need to enter cells to act against the hiv-1 human organic cation transporters (hoct1–3) are expressed and active in cd4+ t cells, the main target of hiv-1, and have been associated with antiviral uptake in different tissues. The human organic anion and cation transporters are classified within two slc superfamilies superfamily slco (formerly slc21a) consists of organic anion transporting polypeptides (oatps), while the organic anion transporters (oats) and the organic cation transporters (octs) are classified in the slc22a superfamily.

Médicaments inhibiteurs des transporteurs des anions organiques (oatp) les conséquences de l'interaction avec les inhibiteurs des transporteurs des anions organiques (oatp) puissants (tels que certaines statines, inhibiteurs de la protéinase, antituberculeux) reste non évaluée. Introduction it has long been established that an important function of the kidney and liver is the secretion of organic anions into the urine and bile, respectively, and it has been recognized that such secretion is an active and saturable process that can be modulated by competitive inhibitors.
