TPENは細胞透過性多座配位重金属キレート剤であり、高い親和性で亜鉛イオンと結合し、Mg2+とCa2+に対しては比較的に低い親和性を持つ[1]。TPENは細胞内亜鉛を消耗し、ROS生成の増加、DNAの損傷とカスパーゼ依存のアポトーシスを惹起し、よって細胞の増殖を阻害する[2]。TPENはよく、腫瘍の治療、低酸素の保護と抗感染の研究に使われる[3-4]。
網膜色素上皮細胞で、TPEN (0.25-4μM;24時間)に暴露された細胞の形態は、幅広く平らな形状から繊維状の形状に変わった[5]。Panc-1細胞で、TPEN (0-6μM;24時間)は活性酸素種(ROS)を増やし、オートファジーを阻害することで、細胞死を著しく誘発した[6]。
アレルギー性喘息の肥満細胞依存性マウスモデルで、TPEN (10mg/kg;腹腔内注射;7日間)は気管支肺胞洗浄液における気道過敏性と好酸球増多を著しく阻害した[7]。糖尿病マウスモデルで、TPEN (5mg/kg;腹腔内注射;4か月)の処理は、肝臓亜鉛レベルにおける糖尿病誘発の減少を更に減らした[8]。

| 細胞実験[1]: | |
細胞株 | 網膜色素上皮細胞 |
準備方法 | 無血清培地で、細胞を0.25から4μMのTPENとその他の薬剤に暴露した。その前に、事前に存在していた培地を数日すすぎ、無血清培地に交換した。無血清暴露培地に必要な体積の貯蔵液を添加することで、TPENとその他の薬剤の暴露を実施した。暴露を除く、同じ培地交換手続きでTPENに対照培養物を暴露した。 |
反応条件 | 0.25-4μM;24時間 |
アプリケーション | TPENに暴露された細胞の形態は、幅広く平らな形状から繊維状の形状に変わった。 |
| 動物実験 [2]: | |
動物モデル | アレルギー性喘息の肥満細胞依存性マウスモデル |
準備方法 | アレルギー性喘息の肥満細胞依存性マウスモデルで、14日間、隔日で、水酸化アルミニウムを含まない10μgの卵白アルブミン(OVA)を腹腔内注射し、C57BL6Jを感作した。40、43と46日目に、マウスには、生理食塩水または1%のOVAを含有するエアロゾルチャレンジを毎日30分間行った。各OVAチャレンジの30分前、マウスには10mg/kgのTPENまたは溶媒溶液を腹腔内注射した。47日目で、最後のエアロゾルチャレンジの24時間後、気道反応性と気管支肺胞洗浄(BAL)の測定を行った。 |
