WebThe weak acid 2,4-dinitrophenol (DNP) acts as an uncoupler of oxidative phosphorylation in biological systems and, in consonance with the Mitchell hypothesis, also enhances the conductance of phospholipid bilayer membranes. Several models have been proposed in the literature to explain the molecular mechanism by which DNP exerts its electrical … WebMitochondrial uncoupling of oxidative phosphorylation is one of the most widely discussed mechanisms underlying the toxicity of NSAIDs [94–98]. This effect can be explained by their chemical structures; many NSAIDs are monocarboxylic acids with one or more aromatic rings and most are lipophilic. These features are typical of uncoupling agents.
