      Ingenol is an extremely weak PKC (protein kinase C) activator; has been found to induce apoptosis and act as an anticancer agent. MedChem Express http://www.medchemexpress.com/20-Deoxyingenol.html, HY-N0865
      Ingenol is an extremely weak PKC (protein kinase C) activator; has been found to induce apoptosis and act as an anticancer agent. ;IC50 value:;Target: anticancer natural compound;In vitro: ingenol indeed binds to protein kinase C with a Ki of 30 microM and activates the enzyme. In addition, ingenol was biologically active in 3 separate cell systems, showing effects similar to the phorbol esters on morphological change, cell-cell communication, epidermal growth factor binding, arachidonic acid metabolite release, and ornithine decarboxylase activity [1].
