1. Glutinol acetate shows significant cytotoxic activity against four human cancer cell lines (HL-60, SK-OV-3, A549, and HT-29), with GI(50) in the range of 11.1-17.9microM; it also has anti-inflammatory effect, exhibits moderate inhibitory activity of TNF-alpha secretion in the lipopolysaccharide (LPS)-stimulated murine RAW264.7 macrophage cell line.

1. Burchellin has larvicidal activity, it can interfer with the development cycle of the mosquito, where its strongest toxic effect is 100% mortality in larvae (L3) at concentrations ≥ 30 ppm.
2. Burchellin and licarin A have activity against Trypanosoma cruzi, they can induce trypomastigote death with IC(50)/24 h of 520 microM and 960 microM, respectively.

1. 4-O-Methylbutein (2',3,4'-trihydroxy-4-methoxychalcone) is a potent heme oxygenase-1 (HO-1) inducer, the upregulation of HO-1 has proven to be a useful tool for fighting inflammation,suggests that 4-O-methylbutein may have anti-inflammation activity.

1. 29-Nor-20-oxolupeol(3 beta-Hydroxy-30-norlupan-20-one) has growth inhibitory effects on HL-60 cells.

1. The hexane-ethanol extract of Glycyrrhiza uralensis, which contains licoricidin, is a potent anti-metastatic agent, which can markedly inhibit the metastatic and invasive capacity of malignant prostate cancer cells.
2. Licoricidin inhibits lung metastasis of 4T1 mammary carcinoma cells, which may be mediated via inhibition of cancer cell migration, tumor angiogenesis, and lymphangiogenesis.
3. Licoricidin and licorisoflavan A are effective in inhibiting the growth of all three bacterial species(Porphyromonas gingivalis, Prevotella intermedia and Solobacterium moorei), with minimal inhibitory concentrations in the range of 2-80 ug /ml, they have a potential for reducing bacterial volatile sulfur compounds (VSCs) production and therefore for controlling halitosis.
4. Licoricidin blocks UVA-induced photoaging via ROS scavenging,this activity converges to limit the activity of MMP-1, suggests that licoricidin may be considered as an active ingredient in new topically applied anti-ageing formulations.
5. Licoricidin and licorisoflavan A have potential for the development of novel host-modulating strategies for the treatment of cytokine and/or MMP-mediated disorders such as periodontitis.

1. 2,3-Dihydrohinokiflavone (IC50 =1.6uM) shows strong activity against Leishmania.
2. 2,3-Dihydrohinokiflavone is a suppressor of matrix metalloproteinases (MMPs) gene expression.
