Somatostatin (GHIH), a peptide hormone, regulates the endocrine system and affects neural transmission and cell proliferation by interacting with G-protein-coupled somatostatin receptors and inhibiting the release of multiple secondary hormones. Somatostatin inhibits secretion of insulin and glucagon.

Terrestrosin D can induce apoptotic cell death and inhibit angiogenesis in xenograft tumor cells, cell cycle arrest and induction of apoptosis in cancer cells and endothelial cells might be plausible mechanisms of actions for the observed antitumor and antiangiogenic activities of terrestrosin D.

Elamipretide is a novel mitochondrion-targeted antioxidant.?Treatment with elamipretide significantly ameliorated LPS-induced learning and memory impairment during behavioral tests.
