Structural Diversity and Biological Activities of Diterpenoids Derived from Euphorbia fischeriana Steud

Diterpenoids are the focus of natural product drug discovery because of their great structural diversity and pronounced biological activities. Euphorbia fischeriana Steud is a Chinese traditional medicinal herb for curing edema, ascites, and cancer. This plant contains rich diterpenoids. Based on the carbon skeleton and substituents, it can be classified into thirteen subtypes: ent-abietane, daphnane, tigliane, ingenane, ent-atisane, ent-rosane, ent-kaurene, ent-kaurane, secotigliane, lathyrane, ent-pimarene, isopimarene and dimeric. In this paper, we reviewed the chemical structures and biological activities of 90 diterpenoids isolated from this medicinal herb. We hope that this work can serve as a reference for further research of these diterpenoids and lay the foundation for drug discovery.
