Ingenol 3,20-dibenzoate is a powerful activator of protein kinase C (PKC) isoforms. It effectively induces the translocation of nPKC-delta, -epsilon, and -theta as well as PKC-mu from the cytosolic fraction to the particulate fraction. Through de novo synthesis of macromolecules, it triggers apoptosis with characteristic morphology. Moreover, Ingenol 3,20-dibenzoate enhances IFN-γ production and degranulation in NK cells, particularly when stimulated by NSCLC cells[1][2].

9(S),12(S),13(S)-TriHOME is a linoleic acid-derived oxylipin that has diverse biological activities.1,2,3,4It has been found in various plants and is produced in human eosinophils in a 15-lipoxygenase-dependent, soluble epoxide hydrolase-independent manner.1,59(S),12(S)13(S)-TriHOME inhibits antigen-induced β-hexosaminidase release from RBL-2H3 mast cells (IC50= 28.7 μg/ml).2It inhibits LPS-induced nitric oxide (NO) production in BV-2 microglia (IC50= 40.95 μM).3In vivo, 9(S),12(S),13(S)-TriHOME (1 g/animal) enhances the antiviral IgA and IgG antibody responses induced by a nasal influenza hemagglutinin (HA) vaccine by 5.2- and 2-fold, respectively, in mice.4 1.Hamberg, M., and Hamberg, G.Peroxygenase-catalyzed fatty acid epoxidation in cereal seeds: Sequential oxidation of linoleic acid into 9(S),12(S),13(S)-trihydroxy-10(E)-octadecenoic acidPlant Physiol.110(3)807-815(1996) 2.Hong, S.S., and Oh, J.S.Inhibitors of antigen-induced degranulation of RBL-2H3 cells isolated from wheat branJ.

1,6-O,O-Diacetylbritannilactone(OODBL) has anti-inflammatory activity, it has a potential therapeutic efficacy on inflammatory diseases especially allergic airway disease as a lead compound. OODBL has anti-asthmatic activity, it reduces leukotriene C4 pro

Isokaempferide shows hepatoprotective, antiproliferative, and anti-inflammatory effects, the anti-inflammatory effects can be explained, at least in part, by reducing neutrophil degranulation, myeloperoxidase activity, mediators as well as TNF-alpha secretion. Isokaempferide is used as a bronchodilator, can induce relaxation of guinea-pig isolated trachea.
