2,5-Di-tert-butylhydroquinone (DBHQ) has been shown to be a selective and potent inhibitor of endoplasmic reticulum Ca2+-ATPase which is shown to cause induction of Ca2+ release from agonist-insensitive and agonist-sensitive intracellular stores. In isolated rat hepatocyte studies, DBHQ was reported to induce a rapid increase in cytosolic Ca2+ concentration without loss of other microsomal enzyme activity, altering membrane permeability, or modification of microsomal protein thiols.
