Cantharidic acid, an inhibitor of protein phosphatases, is first isolated from Chinese blister beetles. Cantharidic acid is a hydrolysis product of cantharidin.
Protein phosphatases, account for virtually all of the phosphatase activity toward phosphoproteins, have been involved in controlling glycogen metabolism, glycolysis, gluconeogenesis, fatty acid synthesis, cholesterol synthesis, and protein synthesis. Protein phosphatases participate in protein phosphorylation, a principal regulatory mechanism in the control of almost all cellular processes [2].
In vitro: Cantharidic acid exihibited inhibitory effects on the protein phosphatases PP1 and PP2A with IC50 values of 0.6 and 0.05 μM, respectively. Cantharidic acid showed no effect on the activity of PP2B or PP2C [1].
In vivo: Intraperitoneal administration of cantharidic acid (10 mg/kg) to mice for 45 min caused extreme liver enlargement and congestion. Treatment with cantharidic acid increased hepatic glycogenolysis, elevated blood glucose and hepatic glycogen phosphorylase levels, reduced hepatic glycogen content and glycogen synthase activity. Cantharidic acid endothal decreased microsomal Mg2+-ATPase levels [3].
