Abstract: Manganese-hyaluronate conjugate (Mn-HA) was synthesized from a diethylenetriaminepentaacetic acid derivative of hyaluronic acid and manganese ion. The conjugate markedly scavenged superoxide anion in vitro and exhibited much higher anti-inflammatory activity than superoxide dismutase in suppressing paw edema in mice when intravenously injected 30 min before the initiation of ischemia.
Keywords: Manganese-hyaluronate conjugate, Ischemic edema, Reactive oxygen species
