It was shown that the terminal part of the succinate dehydrogenase complex contains a site, which specifically binds the negatively charged phenols (e. g. pentachlorophenol, 2,4-dibromophenol, 2-methoxy-4,6-dibromophenol).

The identity of Ki values for PCP under these conditions suggests that the effect of PCP is due to the inhibitor interaction with the same component of the succinate dehydrogenase complex.

These particulate fractions were characterized by their noradrenaline content, succinate dehydrogenase and glucose-6-phosphatase activity.
The behaviour of the 45 Ca2+ -uptake into all three fractions against varying ATP-concentrations, metabolic inhibitors (pentachlorophenol, desaspidine, 2,4-dinitrophenol, N-ethylmaleimide, p-chloromercuribenzoate, sodium azide, amobarbital) and drugs (phenoxybenzamine, verapamil, prenylamine, reserpine, bretylium, phentolamine) was studied.

These rates are stimulated up to 13-fold by addition of protophores (carbonyl cyanide p-trifluoromethoxyphenylhydrazone, carbonyl cyanide m-chloromethoxyphenylhydrazone and pentachlorophenol).
The effect of protophores, ionophores and Ca (2+) is analysed in relation to the propositions of a cyclic mechanism for the interaction of ubiquinone with succinate dehydrogenase and cytochromes b and c (1) [Wikstrom & Berden (1972) Biochim.

Arch Biochem Biophys. 1999 Sep 15;369(2):223-32.

A series of 2-alkyl-4,6-dinitrophenols and pentachlorophenol were found to be potent competitive inhibitors of both SQR and QFR.

In the diluted system the inactivation of the ubiquinone-depleted enzyme was completely prevented by the saturating concentrations of Q2, carboxin, thenoiltrifluoroacetone and pentachlorophenol, i.e., by the substrate and specific inhibitors of the enzyme.
When the soluble reconstitutively active succinate dehydrogenase was treated with pyridoxal phosphate, the reactivity of the enzyme towards low ferricyanide concentrations and its reconstitutive activity was significantly protected against aerobic inactivation.
