Notes: Homogentisic acid lactone is a fungal metabolite that has been found in the fungus WF5, has fungicidal activity, and is the lactonized form of homogentisic acid (Item No. 20045), an intermediate in aromatic amino acid metabolism.{72427} It is active against the plant pathogenic fungus F. graminearum. Homogentisic acid lactone has been used as a substrate in the determination of serum paraoxonase/arylesterase 1 (PON1) activity and the chemiluminescent detection of HRP release from liposomes.{72428,72429} It is an intermediate in the synthesis of LD-2, a near-infrared probe for the imaging of lipid droplets in live cells.{72430}
