Artemisinins are sesquiterpene lactones with a peroxide moiety that are isolated from the herb Artemisia annua. It has been used for centuries for the treatment of fever and chills, and has been recently approved for the treatment of malaria due to its endoperoxidase properties. Progressively, research has found that artemisinins displayed multiple pharmacological actions against inflammation, viral infections, and cell and tumour proliferation, making it effective against diseases.

A murine monoclonal antibody (mAb), CLD3 (IgG(1),kappa), was generated against hepatocellular carcinoma (HCC). Both immunofluorescence and immunohistochemical assays indicated the reactivity of CLD3 mAb localized at the nucleus and/or cytoplasm of tumorigenic HCC cell lines as well as in liver cancer tissues. By immunoprecipitation and using the matrix-assisted laser desorption/ionization-time of flight mass spectrometry approach, the antigenic specificity of CLD3 was determined to be heterodimeric Ku70 and Ku80 autoantigen, which was confirmed by Western blotting.

Trocarin, a Group D prothrombin activator from Tropidechis carinatus snake venom, has high sequence similarity to blood coagulation factor Xa (FXa). Both trocarin and FXa activate prothrombin to mature thrombin and have similar requirements for cofactors, such as factor Va, Ca2+ ions and phospholipids. In addition to its hemostatic functions, human FXa causes inflammation and induces mitogenesis in several cell types due to its interaction with effector protease receptor-1 (EPR-1).
