Modelling of p-tyramine transport across human intestinal epithelial cells predicts the presence of additional transporters

open access: yesFrontiers in Physiology, 2022
p-Tyramine (TYR) is an endogenous trace amine, which can also be synthesized by intestinal microbiota, and is present in commonly consumed diets. TYR is an agonist for the intracellular trace amine-associated receptor 1, which has been implicated in ...

Proguanil and cycloguanil are organic cation transporter and multidrug and toxin extrusion substrates

open access: yesMalaria Journal, 2017
Background Malaria, HIV/AIDS, and tuberculosis endemic areas show considerable geographical overlap, leading to incidence of co-infections. This requires treatment with multiple drugs, potentially causing adverse drug–drug interactions (DDIs).

Role of OCT2 and MATE1 in renal disposition and toxicity of nitidine chloride [PDF]

open access: yesBritish Journal of Pharmacology, 2016
Background and PurposeNitidine chloride (NC), a benzophenanthridine alkaloid, has various biological properties including anticancer and analgesic activities. The aim of the present study was to evaluate the role of organic cation transporter 2 (OCT2) and multidrug and toxin extrusion 1 (MATE1) in the renal disposition and nephrotoxicity of NC ...

A Whole-Body Physiologically Based Pharmacokinetic Model Characterizing Interplay of OCTs and MATEs in Intestine, Liver and Kidney to Predict Drug-Drug Interactions of Metformin with Perpetrators

open access: yesPharmaceutics, 2021
Transmembrane transport of metformin is highly controlled by transporters including organic cation transporters (OCTs), plasma membrane monoamine transporter (PMAT), and multidrug/toxin extrusions (MATEs).

Evaluation of drug–drug interaction potential for pemigatinib using physiologically based pharmacokinetic modeling

open access: yesCPT: Pharmacometrics & Systems Pharmacology, 2022
Pemigatinib is a potent inhibitor of fibroblast growth factor receptor being developed for oncology indications. It is primarily metabolized by cytochrome P450 (CYP) 3A4, and the ratio of estimated concentration over concentration required for 50 ...

Gender differences in expression of organic cation transporter OCT2 in rat kidney [PDF]

open access: yesFEBS Letters, 1999
The organic cation transporter (OCT) mediates translocation of various cationic molecules including drugs, toxins and endogenous substances. We examined gender differences in the expression of rat (r) OCT2 in the kidney. Slices and basolateral membrane vesicles of male rat kidney showed a higher transport activity for tetraethylammonium than those of ...

Substrates and Inhibitors of the Organic Cation Transporter 3 and Comparison with OCT1 and OCT2

open access: yesJournal of Medicinal Chemistry, 2022
Organic cation transporters (OCTs) 1, 2, and 3 facilitate cellular uptake of structurally diverse endogenous and exogenous substances. However, their substrate and inhibitor specificity are not fully understood. We performed a broad in vitro screening for OCT3 substrates and inhibitors, allowing us to compare the substrate spectra and to study the ...

Molecular Principles of Oct2-Mediated Gene Activation in B Cells

open access: yesImmunobiology, 1995
The octamer motif is a crucial regulatory element for immunoglobulin promoter and enhancer function. We have investigated the molecular mechanisms that underlie octamer-mediated gene activation in B cells. This B cell-specific transcriptional regulation is subject to a novel type of regulatory mechanism.
