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.
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.

Discover Bioactive Small Molecules for Apoptosis

Apoptosis, or programmed cell death (PCD), is a selective process for the removal of unnecessary, infected or transformed cells in various biological systems. As it plays a role in the homeostasis of multicellular organisms, apoptosis is tightly regulated through two principal pathways by a number of regulatory and effector molecules.

Discover Bioactive Small Molecules for Cell Cycle Research

n proliferating cells, the cell cycle consists of four phases. Gap 1 (G1) is the interval between mitosis and DNA replication that is characterized by cell growth. Replication of DNA occurs during the synthesis (S) phase, which is followed by a second gap phase (G2) during which growth and preparation for cell division occurs. Together, these three stages comprise the interphase phase of the cell cycle. Interphase is followed by the mitotic (M) phase.
