Acute Tox. 4 (100%)
Acute Tox. 4 (100%)
Naturally occurring or synthetic substances that inhibit or retard oxidation reactions. They counteract the damaging effects of oxidation in animal tissues.
Drugs used to protect against ionizing radiation. They are usually of interest for use in radiation therapy but have been considered for other purposes, e.g. military.
用途生体試料のESRスピンラベル化試薬。
用途TEMPOL(テンポル)正式名称は4-ヒドロキシ-2,2,6,6-テトラメチルピペリジン-1-オキシルという。 TEMPOと同様に、安定なラジカルとして酸化剤や触媒に使われる。TEMPOLの利点はTEMPOに比べて非常に価格が安いことである。TEMPOLはアンモニアとアセトンを濃縮して作られるトリアセトンアミンから合成される。値段が安いため、産業用としても利用されている。 医薬品では、活性酸素の分解を促進する物質となる。TEMPOLは超酸化物の不均化を触媒し、過酸化水素の代謝を促進し、フェントン試薬の体内での発生を抑えるはたらきがある。
説明TEMPOL is a piperidine nitroxide and spin label with superoxide dismutase (SOD) mimetic activity. It inhibits lipid peroxidation in rat liver microsomes with 50% inhibition of microsomal lipid peroxidation (IP50) values of 117, 61, and 381 μM for peroxidation induced by iron plus NADPH, iron plus ascorbate, and t-butylhydroperoxide, respectively. TEMPOL (1 mM) inhibits production of superoxide anions by 92% via a xanthine-xanthine oxidase reaction in vitro. It reduces mean arterial pressure and heart rate in spontaneously hypertensive rats (ED50s = 70 and 63 μmol/kg, respectively) when administered intravenously. TEMPOL is a cell-permeable spin label that has been used to quantify intracellular oxygen in various cell types by electron spin resonance (ESR) spectroscopy.
使用A free radical scavenger
一般的な説明4-Hydroxy-TEMPO is a 4-substituted 2,2,6,6-tetramethylpiperidyl-1-oxy (TEMPO) derivative. It is a low-molecular weight compound and has been proposed as superoxide dismutase mimic.
