| Description | TPEN (16858-02-9) is a cell permeable metal chelator. Frequently used to study effects of zinc depletion on cellular processes.1,2 | | Chemical Properties | Colourless Crystals | | Uses | Membrane-permeable zinc chelator; decreased the intracellular level of zinc and induced apoptosis. | | Definition | ChEBI: An N-substituted diamine that is ethylenediamine in which the four amino hydrogens are replaced by 2-pyridylmethyl groups. | | 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. | | storage | Store at +4°C | | References | 1) Chimienti et al.
