Quercetin, quercetrin except rutin potentially increased pirarubicin cytotoxicity by non-competitively inhibiting the P-glycoprotein-and MRP1 function in living K562/adr and GLC4/adr cells
Problem statement: Quercetin and its glycoside derivatives are increasingly receiving interests as new generation of anticancer molecules and were recognized by multidrug resistant transporters such as P-glycoprotein and MRP1 protein. Of relevance to their use as anticancer agents alone or in combin...

Problem statement: Quercetin and its glycoside derivatives are increasingly receiving interests as new generation of anticancer molecules and were recognized by multidrug resistant transporters such as P-glycoprotein and MRP1 protein. Of relevance to their use as anticancer agents alone or in combination with other agents, this study aims to analyze the interaction of the compounds with the MDR transporters including P-glycoprotein and MRP1 protein in living multidrug resistant cells. Approach: The potential MDR reversing action of flavonoids was assessed by using the cotreatment of anticancer drug, pirarubicin or daunorubicin and quercetin, quercetrin or rutin compared with the series of co-treatment of pirarubicin or daunorubicin and the known inhibitor such as cyclosporine A and verapamil.
