Terreic Acid

    WARNING: This product is for research use only, not for human or veterinary use.

MedKoo CAT#: 329675

CAS#: 121-40-4

Description: Terreic Acid is a cell-permeable quinone epoxide that selectively inhibits Bruton’s tyrosine kinase (BTK) catalytic activity (IC50s = 10 and 3 µM for basal and activation levels, respectively). Terreic Acid recapitulated the phenotypic defects of btk mutant mast cells in high-affinity IgE receptor-stimulated wild-type mast cells without affecting the enzymatic activities and expressions of many other signaling molecules, including those of protein kinase C. Terreic acid is a covalent inhibitor of the bacterial cell wall biosynthetic enzyme UDP-N-acetylglucosamine 1-carboxyvinyltransferase (MurA) .
