Biochem/physiol Actions

Cell-permeable iron chelator and top2a activity inhibitor
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.[1] Dp44mT is known to promote apoptosis in neuroepithelioma, melanoma and breast cancer.[2]
Dp44mT is an iron chelator that works as a selective anticancer agent. As other iron chelators it can serve as a therapeutic adjunct to doxorubicin treatment. Additionally Dm44mT possess DNA-damaging activity. It appears that that activity is mediated by top2a inhibition.
