Common NameNorbadione A
DescriptionNorbadione A belongs to the class of organic compounds known as pentacarboxylic acids and derivatives. These are carboxylic acids containing exactly five carboxyl groups. Norbadione A is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, norbadione a has been detected, but not quantified in, mushrooms. This could make norbadione a a potential biomarker for the consumption of these foods. There is a pH-dependent Z to E isomer switch that occurs in both pulvinate moieties, which yields four stereoisomeric forms (E/E, E/Z, Z/Z, Z/E). A series of alkali chelators based on the structure of norbadione A has been reported. The molecule has also been reported as a potassium salt from the mushrooms Pisolithus tinctorius (horse dung fungus) and Chalciporus piperatus. Bourdreux and colleagues reported a total synthesis of norbadione A in 2008. These functional groups confer water-solubility to the molecule. It has been investigated for its ability to provide a protective effect against the damaging effects of ionizing radiation, an effect attributed to its ability to protect DNA-related targets from irradiation. A polyphenol, norbadione A is related to a family of mushroom pigments known as pulvinic acids.
