TPEN

TPEN (TPEDA) 是一種特定的細(xì)胞可滲透的重金屬螯合劑。TPEN 對(duì) Zn2+ 具有高親和力,但對(duì) Mg2+ 和 Ca2+ 具有較低的親和力。TPEN 誘導(dǎo) DNA 損傷并增加細(xì)胞內(nèi) ROS 的產(chǎn)生。TPEN 還抑制細(xì)胞增殖并誘導(dǎo)凋亡 (apoptosis)。

生物活性

TPEN (TPEDA) is a specific cell-permeable heavy metal chelator. TPEN has a higher affinity for Zn2+, but a lower affinity for Mg2+ and Ca2+. TPEN induces DNA damage and increases intracellular ROS production. TPEN also inhibits cell proliferation and induces apoptosis


體外研究(In Vitro)

Heavy metal chelator TPEN attenuates fura-2 fluorescence changes induced by cadmium, mercury and methylmercury. TPEN, a cell-permeable chelator for heavy metal cations with a low affinity for Ca2+. In cells stimulated with 10 or 30 μM cadmium chloride, the addition of TPEN at 3 hr after exposure significantly decreases the elevated fura-2 fluorescence ratio to the basal levels within 10 min (119.6±2.4% or 109±1.5% decrease in ΔRatio (F340/F380) induced by 10 or 30 μM cadmium chloride, respectively), suggesting that a cadmium chloride-induced increase in the fura-2 fluorescence ratio is dependent on an increase in intracellular heavy metal cations but not intracellular Ca2+[1]. TPEN is a metal chelator, which targets colon cancer cells through redox cycling of copper. TPEN reduces cell viability in a dose- and time-dependent manner. TPEN-induced cell death is also dependent on the redox cycling of copper since the copper chelator neocuproine inhibited DNA damage and reduced pChk1, γ-H2AX, and ATM protein expression. Cell death by low TPEN concentrations, involved ATM/ATR signaling in all 3 cell lines, since pre-incubation with specific inhibitors of ATM and DNA-PK led to the recovery of cells from TPEN-induced DNA damage
