Hyperoside was shown to exert an anti-inflammatory action through suppressed production of tumor necrosis factor, interleukin-6, and nitric oxide in lipopolysaccharide-stimulated mouse peritoneal macrophages. Hyperoside inhibited nuclear factor-κB activation and IκB-α degradation. Hyperoside inhibited H2O2-induced apoptosis in Chinese hamster lung fibroblast (V79-4) cells, as shown by decreased apoptotic nuclear fragmentation, decreased sub-G(1) cell population, and decreased DNA fragmentation. Hyperoside pretreatment inhibited the H2O2-induced activation of caspase-3 measured in terms of levels of cleaved caspase-3. Hyperoside prevented H2O2-induced lipid peroxidation as well as protein carbonyl.Hyperoside prevented the H2O2-induced cellular DNA damage, which was established by comet tail, and phospho histone H2A.X expression. Hyperoside increased the catalase and glutathione peroxidase activities. Hyperoside may induce endothelium-dependent and endothelium-independent responses. Hyperoside as a candidate therapeutic agent for the treatment of vascular inflammatory diseases via inhibition of the HMGB1 signaling pathway.

| Animal A (mg/kg) = Animal B (mg/kg) multiplied by | Animal B Km |
| Animal A Km |
For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
