Scoparone markedly reduced the serum-stimulated accumulation of cells in the S phase and concomitantly increased the proportion of cells in the G0/G1 phase, which was consistent with the reduced expression of cyclin D1, phosphorylated Rb and survivin in the VSMCs. Cell adhesion markers, such as MCP-1 and ICAM-1, were significantly reduced by scoparone. Scoparone blocks the accumulation of STAT3 transported from the cytosol to the nucleus, leading to the suppression of VSMC proliferation through G1 phase arrest and the inhibition of Rb phosphorylation. Scoparone elicits an anti-tumor effect against DU145 prostate cancer cells in part through inhibition of STAT3 activity. Therapeutic effect of scoparone could regulated the dysfunctions of citrate cycle, sphingolipid metabolism, taurine and hypotaurine. Scoparone treatment remarkably attenuated LPS-induced pulmonary edema, histological severities, myeloperoxidase activity, and TNF-α, IL-6 and IL-1β production in vivo. Scoparone inhibited LPS-induced TLR4 expression, NF-κB activation, TNF-α, IL-6 and IL-1β production in alveolar macrophages in vitro.

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 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 resveratrol of 11.2 mg/kg.
