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.

純化方法

Crystallise the hydroquinone from *C6H6 or AcOH. [Beilstein 6 III 4741.]
