Peroxalate ester linkages
in the backbone reacted with and scavenged hydrogen peroxide, leading the release of HBA in vitro.
HBA released from HPOX exerted excellent antioxidant activity, such as inhibition of nitric oxide (NO)
production by suppressing iNOS (inducible nitric oxide synthases) expression in lipopolysaccharide
(LPS)-activated RAW 264.7 cells.
