Uncoupling agents
WebBy and large, the uncoupling agents now in general use were discovered as side effects of drugs that had been shown to affect other ion channels. Little attention has been given to optimization of specificity through pharmacokinetic manipulation, and it is not surprising that these tools are lacking. WebIn the brown fat cells, uncoupling proteins are produced and inserted into the inner mitochondrial membrane. These proteins are simply channels that allow protons to pass from the intermembrane space to the matrix without traveling through ATP synthase. ... Dinitrophenol (DNP) is a chemical that acts as an uncoupling agent, making the inner ...
