Application
Methyl-p-benzoquinone (MBQ) can be used as a coating that forms an interface between the electrode and lithium (Li) electrolyte for the fabrication of redox flow batteries. It can be reduced during positive electrospray ionization mass spectroscopy (ESI MS) and can be potentially used during corona discharge.

Inactivation kinetics of pyruvate decarboxylase under joint action of substrate and substituted quinones in aqueous solutions which contain 1.0-13.5 vol.% of methyl alcohol has been investigated. The observed inactivation rate constant of pyruvate decarboxylase sharply decreases with the increase of

Unexpected reduction of iminoquinone (IQ) and quinone derivatives was first reported during positive electrospray ionization mass spectrometry. Upon increasing spray voltage, the intensities of IQ and quinone derivatives decreased drastically, accompanying the increase of the intensities of the reduction products

The rate constants of NADH oxidation by quinones are increased with the oxidation potential increase: log kox (M-1 X s-1) = -0.25 + 12.2 E0(7) (V) for o-quinones and log kox (M-1 X s-1) = -3.06 + 13.5 E0(7) (V)

The defensive glands of beetles, Tenebrio molitor, infected with metacestodes (cysticercoids) of Hymenolepis diminuta are everted less frequently upon stimulation, and contain less toluquinone (methylbenzoquinone) and m-cresol, than glands of uninfected controls. These differences, as shown in predation trials with

In the course of our search for antimalarial leads from marine algae, four metabolites, sargaquinoic acid, sargahydroquinoic acid, sargaquinal and fucoxanthin, were isolated from the South African alga Sargassum heterophyllum. Fucoxanthin and sargaquinal showed good antiplasmodial activity toward a chloroquine-sensitive
