NCIt definition : A short-chain diterpene ester isolated from the seed of Fontainea picrosperma, with
potential antineoplastic activity. Upon intratumoral administration, tigilanol tiglate
disrupts mitochondrial functioning and induces mitochondrial swelling, which leads
to oncolysis of tumor cells that are in direct contact of the agent. In addition,
tigilanol tiglate activates protein kinase C (PKC) signaling cascade, which leads
to an acute inflammatory response. This results in hypoxia and activates innate immune
cells including neutrophils and macrophages, thereby further killing tumor cells.
The activation of the beta-II isoform of PKC (PKC beta II ) also increases tumor vasculature
permeability, which leads to the destruction of tumor vasculature.;
