Application

N,N,N′,N′-Tetrakis(2-pyridylmethyl)ethylenediamine has been used:
  • in the treatment of human embryonic kidney (HEK293T) cells for assessing its effect on the Jembrana disease virus (JDV) viral infectivity factor (Vif) functionality
  • in P19 embryonic carcinoma cells for chelation of zinc ions released during apoptosis
  • to evaluate its effect on lentiviral Vpx infection on human monocytic THP-1 cells

Biochem/physiol Actions

N,N,N′,N′-Tetrakis(2-pyridylmethyl)ethylenediamine (TPEN) elicits pro-apoptotic effect in human acute promyelocytic NB4 cells by inhibiting nitric oxide signalling and Zn2+ signaling. In microglia pretreated with zinc, TPEN inhibits the interleukin 6 secretion and nitric oxide synthase (iNOS) mRNA expression. It induces damage on DNA structure by activating ATM (ataxia telangiectasia mutated) and ATR (ATM-Rad3-related) signaling in human colon cancer cells.
TPEN is a membrane-permeable zinc chelator; decreased the intracellular level of zinc and induced apoptosis (i.e., cell shrinkage and formation of apoptotic bodies with DNA fragmentation and formation of a typical DNA ladder pattern).

The essential element zinc plays critical roles in biology. High zinc homeostasis mechanisms are beginning to be defined in animals, but low zinc homeostasis is poorly characterized. We investigated low zinc homeostasis in Caenorhabditis elegans because the genome encodes 14

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.

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.
