The glutathione S-transferase inhibitor 6-(7-nitro-2,1,3-benzoxadiazol-4-ylthio)hexanol overcomes the MDR1-P-glycoprotein and MRP1-mediated multidrug resistance in acute myeloid leukemia cells

摘要

Purpose There has been an ever growing interest in the search for new anti-tumor compounds that do not interact with MDR1-Pgp and MRP1 drug transporters and so circumvent the effect of these proteins conferring multidrug resistance (MDR) and poor prognosis in AML patients. We have investigated the cytotoxic activity of the strong glutathione S-transferase (GST) inhibitor 6-(7-nitro-2,1,3-benzoxadiazol-4-ylthio)hexanol (NBDHEX) on AML (HL60) cell lines.
