Cat No.
CEI-1321
Description
Elacridar (GF120918; GW0918) is an inhibitor of P-glycoprotein.
Product Overview
Elacridar is a potent inhibitor of P-glycoprotein with IC50 values of 193 nM. P-glycoprotein (permeability glycoprotein) is an important membrane protein. It pumps many foreign substances out of cells. P-glycoprotein belongs to the MDR/TAP subfamily. P-glycoprotein is transmembrane glycoprotein which is about 170 kDa. It is expressed in certain cell types primarily in the pancreas, liver, colon and kidney. It contains 6 transmembrane domains in the N-terminal half of the molecule. It also contains an ATP-binding site in the large cytoplasmic domain. P-glycoprotein binds to the substrate at the cytoplasmic side of the protein. When ATP binds to the cytoplasmic side, the substrate was excreted from the cell. P-glycoprotein can pump toxins or drugs back into the intestinal lumen, pumps them into bile ducts in liver cells. In some cancer cells, P-glycoprotein is overexpressed. It is involved in multidrug resistance of cancer cells. Elacridar can significantly inhibit the activity of P-glycoprotein at 1μM in MDCKII cells which overexpress P-glycoprotein. In the parental MDCK-II cells, elacridar at 5μM completely inhibit the polarized sunitinib transport. Elacridar did not inhibit the activity of several human cytochromeP450 enzymes in vitro. The absolute bioavailability was about 0.47 and 1.3 respectively, when elacridar was given in the orally and microemulsion, intraperitoneally at 10 mg/kg in mice. Elacridar also can significantly increase sunitinib brain accumulation levels in mice at 10 mg/kg.
