Marginatoxin may be a promising chemopreventive agent for treating hepatocellular carcinoma, it induces human hepatoma BEL-7402 cells apoptosis in vitro and in vivo via activation of Fas/FasL-mediated apoptotic pathway.

Somatostatin, also known as growth hormone-inhibiting hormone, is a naturally-occurring peptide hormone of 14 or 28 amino acid residues that regulates the endocrine system. It is secreted by the D cells of the islets to inhibit the release of insulin and glucagon, and is also generated in the hypothalamus, where it inhibits the release of growth hormone and thyroid-stimulating hormones from the anterior pituitary.Somatostatin is a tetradecapeptide which can suppress the growth hormone (GH) secretion and control the pituitary hormone secretion in human CNS.

Ganolucidic acid E inhibits the growth of three types of human cancer cells: Caco-2, HepG2 and HeLa cells.
