Description

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).
