Glutathione Transferases Sequester Toxic Dinitrosyl-Iron Complexes in Cells
It is now well established that exposure of cells and tissues to nitric oxide leads to the formation of a dinitrosyl-iron complex bound to intracellular proteins, but little is known about how theExpand

A Strong Glutathione S-Transferase Inhibitor Overcomes the P-glycoprotein-mediated Resistance in Tumor Cells
The new glutathione S-transferase inhibitor 6-(7-nitro-2,1,3-benzoxadiazol-4-ylthio)hexanol (NBDHEX) is cytotoxic toward P-glycoprotein-overexpressing tumor cell lines, i.e. CEM-VBL10, CEM-VBL100,Expand
