Biological Activity

Description Scoparone (6,7-dimethoxycoumarin, Aesculetin dimethyl ether, 6,7-Dimethylesculetin, Escoparone) is a natural organic compound discovered from Chinese herb Artemisia scoparia with anticoagulant, hypolipidemic, vasorelaxant, antioxidant, and anti-inflammatory actions.
In vitro

The proliferation of VSMCs is significantly attenuated by scoparone in a dose-dependent manner. Scoparone markedly reduces the serum-stimulated accumulation of cells in the S phase and concomitantly increases the proportion of cells in the G0/G1 phase, which is 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, are significantly reduced by scoparone. It attenuates the increase in cyclin D promoter activity by inhibiting the activities of both the WT and active forms of STAT3. 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. This activity occurs independent of the form of STAT3 and upstream of kinases, such as Jak and Src, which are correlated with abnormal vascular remodeling due to the presence of an excess of growth factors following vascular injury. The protective effect of scoparone involves anti-inflammatory functions that occur via the inhibition of NF-κB activity, leading to the downregulation of pro-inflammatory cytokines and chemokines, such as tumor necrosis factor (TNF)-α, interleukin (IL)-6, IL-8 and monocyte chemoattractant protein (MCP)-1[1].

In vivo The free radical scavenging property of scoparone leads to the attenuation of intima thickening and improves hemodynamics in cholesterol-fed alloxan-diabetic rabbits concurrent with decreases in plasma lipid and lipoprotein cholesterol concentrations[1]. Scoparone exhibited therapeutic efficacies on liver damage in vivo[2].

Protocol (from reference)

Cell Research:[1]
  • Cell lines: rat VSMCs
  • Concentrations: 500 μM
  • Incubation Time: 24 h
  • Method: The rat VSMCs are seeded in six-well plates at 90% confluence and are starved in serum-free media for 24 h followed by incubation in 1% FBS for an additional 24 h. The cells in the wells are detached by razor scraping, rinsed with PBS, stimulated in media containing 20% FBS, co-treated with 0.2% DMSO or 500 μM scoparone for 24 h and then stained with hematoxylin. Cell images are obtained via microscopy.
