Inhibition of glucose transport by benzoquinone and the addition product of benzoquinone and dithiothreitol

Biochimica et Biophysica Acta (BBA) - Biomembranes, 1981
Hydroxylated benzene derivatives inhibited transport of d-glucose into calf-thymocyte plasma-membrane vesicles. The relative effectiveness of these was pyrogallol >hydroquinone ≅ catechol ⪢ phloroglucinol. The most thoroughly studied of these agents, hydroquinone, produced weak, immediate inhibition when first added to membranes (Ki > 10 mM).

Thermochemistry of benzoquinones

The Journal of Chemical Thermodynamics, 2004
A thermochemical study of the p-benzoquinone and the duroquinone has been performed by different calorimetric techniques. Applying heat flux calorimetry and differential scanning calorimetry, the enthalpies of fusion for each substance were measured. Enthalpies of combustion in condensed phase were determined by static bomb combustion calorimetry hence

Spin-Carrying Benzoquinone Derivatives

The Journal of Organic Chemistry, 2009
Several 1,4-benzoquinone derivatives carrying oxy-TEMPO radical(s) at the 2-position or 2,5-positions were found to give black crystals by recrystallization from pale yellow solutions and it was revealed from their crystal structures that unusual single-component CT complexes were formed, in which a nitroxide moiety plays the roll of a donor part and a
