| 2,5-ジ-tert-ブチルヒドロキノン Usage And Synthesis |
外観 | 白色~わずかにうすい褐色, 結晶性粉末~粉末 | 溶解性 | エタノール及びアセトンに溶けやすく、水にほとんど溶けない。 | 用途 | 酸化防止剤。有機ゴム薬品(老化防止剤)。 | 化学的特性 | cream or pale brown solid | 使用 | 2,5-Di-tert-butylhydroquinone is the oxidation substrate used to measure the catalytic activity of the copper(II) enzyme-like catalysts. | 定義 | ChEBI: A member of the class of hydroquinones that is benzene-1,4-diol substituted by tert-butyl groups at position 2 and 5. | 一般的な説明 | Mobilizes Ca2+ specifically from the Ins(1,4,5)P3-sensitive Ca2+ stores by inhibiting microsomal and sarcoplasmic reticulum Ca2+-ATPase activity. Does not affect mitochondrial Ca2+ fluxes or plasma membrane Ca2+/Mg2+ ATPase activity. Useful for the study of endomembrane Ca2+ stores and plasma membrane Ca2+ permeability pathways. | 生物活性 | A selective inhibitor of endoplasmic reticulum Ca 2+ -ATPase. | Biochem/physiol Actions | 2,5-Di-tert-butylhydroquinone specifically inhibits the sarcoplasmic reticulum (SR) Ca2+ uptake in the rat ventricle. | 純化方法 | Crystallise the hydroquinone from *C6H6 or AcOH.
