3,29-O-Dibenzoyloxykarounidiol is a natural product with regulate blood sugar level, has potent inhibitory effects on Epstein-Barr virus early antigen (EBV-EA) induced by tumor promoter 12-O-tetradecanoylphorbol-13-acetate (TPA).

Halofuginone specifically inhibits collagen type I gene expression and matrix metalloproteinase 2 (MMP-2) gene expression, which may result in the suppression of angiogenesis, tumor stromal cell development, and tumor cell growth. Halofuginone Hydrobromide is the hydrobromide salt of halofuginone, a semisynthetic quinazolinone alkaloid anticoccidial derived from the plant Dichroa febrifuga, with antifibrotic and potential antineoplastic activities. These effects appear to be due to halofuginone-mediated inhibition of the collagen type I and MMP-2 promoters. Collagen type I and MMP-2 play important roles in fibroproliferative diseases.

7-Methoxyrosmanol (7-O-Methylrosmanol) can effectively suppress FSK-induced luciferase expression under the control of the CRE, PEPCK-C and G6Pase gene promoters, it may contribute to its antihyperglycemic activity.

Kadsurin has anti-oxidant activity, it induces enzymes capable of scavenging oxygen radical species in the liver. Kadsurin may be valuable antitumor promoters or chemopreventors.

20-Deoxyingenol 3-angelate and ingenol 20-acetate 3-angelate are known as promoters of tumors of mouse skin. 20-Deoxyingenol 3-angelate can induce significant platelet aggregation accompanied by induction of phosphorylation of PKC substrates in platelets,

Interiotherin C may be valuable antitumor promoters or chemopreventors.
