Biochem/physiol Actions

3,4,5,6-Tetrahydroxyxanthone is a Na/K-ATPase inihibitor that inhibits pump function without activating the kinase signaling function.
3,4,5,6-Tetrahydroxyxanthone is a Na/K-ATPase inihibitor that inhibits pump function without activating the kinase signaling function. It inhibits Na/K ATPase pump action with an affinity comparable to ouabain, but does not alter Na or ATP affinity, is not blocked by potassium, and it does not activate the Src complex or downstream kinases.

Preparation Note

3,4,5,6-Tetrahydroxyxanthone hydrate is soluble in DMSO at a concentration that is greater than 10 mg/ml.

Statins, known as inhibitors of 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase, exhibit numerous functions related to inflammation, such as MHC class II down-regulation, interference with T cell adhesion, and induction of apoptosis. Here we demonstrate that both subcutaneous and oral administration
