Pharmacoperones are hydrophobic molecule drugs that enter cells and serve as a molecular framework to cause misfolded mutant proteins to fold properly and adopt a stable conformation compatible with proper intracellular trafficking. Pharmacoperones have successfully been used experimentally to rescue function of some misfolded proteins (enzymes, receptors, channels) that lead to disease. Identification of pharmacoperones by high-throughput screens of drug libraries will likely provide new molecules that may be potentially useful to treat diseases caused by protein misfolding.
