Common Name

Pisatin

Description

Pisatin belongs to the class of organic compounds known as pterocarpans. These are benzo-pyrano-furano-benzene compounds, containing the 6H-[1]benzofuro[3,2-c]chromene skeleton. They are derivatives of isoflavonoids. Pisatin is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, pisatin has been detected, but not quantified in, several different foods, such as common pea, herbs and spices, pulses, and tea. This could make pisatin a potential biomarker for the consumption of these foods. In addition, many microbial species have been found to have the ability to detoxify pisatin, but the most virulent strains have the highest rate of demethylation. Three malonyl-CoA moities are then added and cyclized to introduce a phenol ring. The reduction of a carbonyl to a hydroxyl group and the loss of water then forms (+)maackiain, which undergoes stereochemical rearrangement and hydroxylation to form (+)6a-hydroxymaackiain. This molecule is slightly soluble in water and has high solubility in organic solvents. An enzyme known as pisatin demethylase is responsible for this catalysis and has been identified in N. haematococca as a cytochrome P450 enzyme.
