Iron Chelator, Dp44mT is a cell-permeable di-2-pyridyl thiosemicarbazone (DpT) based tridentate ligand.
Biochem/physiol Actions
Dp44mT (di-2-pyridylketone-4,4,-dimethyl-3-thiosemicarbazone) influences lysosome integrity through copper binding. It induces reactive oxygen species (ROS) generation by redox cycling of iron complex. Dp44mT exhibits anti cancer action by attenuating Ndrg-1 (N-myc downstream regulated 1), a metastasis suppressor protein. It also alters the cyclin family of proteins (A, B, D1, D2,D3 and cyclin-dependent kinase 2) known for cell-cycle regulation. Dp44mT is known to promote apoptosis in neuroepithelioma, melanoma and breast cancer.
