Descrição geral
Membrane Preparations for Vesicular Transport Assays (VT) are suitable for general drug-efflux transporter interaction studies. Both substrate and inhibitor interactions can be assessed using vesicles. The success of substrate interaction studies strongly depends on the passive permeability of the compound. High permeability substrates might not be detected. Control Membranes with no-, or significantly lower transporter activity are also available.
Aplicação
In the vesicular transport assay so-called "inside-out" membrane vesicles containing ABC transporters are applied. Incubating substrates of the respective efflux transporter in the presence of the inverted membrane vesicles and ATP will allow measuring accumulation of the substrates into the vesicles. In many cases radiolabeled reporter substrates are used but recently SOLVO developed the new PREDIVEZTM Vesicular Transport Kits that use fluorescent reporter substrates.
The standard vesicular transport assay is an inhibitory assay performed with cold test articles. This assay provides information on any interaction between the ABC transporter and the test article. The transport of the reporter substrate is measured in the presence of the test article (typically in 7 concentrations) and IC50 is defined as the concentration inhibiting the transport of the reporter substrate by 50%.
Should radiolabeled form of the investigated compound or adequate analytical methods (LC/MS, HPLC) be available, the vesicular transport assay may be performed in a direct format without the reporter substrate and may identify substrate nature of the test article. The vesicular transport substrate assay is a low throughput assay. It is suitable for low permeability test compounds as high permeability compounds may escape from the vesicles through the lipid bilayer.

Estradiol 17ß-D-glucuronide (E17G) induces acute cholestasis in rat with endocytic internalization of the canalicular transporters bile salt export pump (Abcb11) and multidrug resistance-associated protein 2 (Abcc2). Classical protein kinase C (cPKC) and PI3K pathways play complementary roles in E17G cholestasis.

In estradiol 17β-d-glucuronide (E17G)-induced cholestasis, the canalicular hepatocellular transporters bile salt export pump (Abcb11) and multidrug-resistance associated protein 2 (Abcc2) undergo endocytic internalization. cAMP stimulates the trafficking of transporter-containing vesicles to the apical membrane and is able to prevent internalization

CI-1034, an endothelin-A receptor antagonist was being developed for pulmonary hypertension. Drug-drug interaction studies using human hepatic microsomes were conducted to assess CYP1A2, CYP2C9, CYP2C19, CYP3A4 and CYP2D6 inhibition potential; CYP3A4 induction potential was evaluated using primary human hepatocytes. CI-1034
