Cortistatin-14 is an endogenous neuropeptide agonist of somatostatin receptors (IC50s = 0.5-18.2 nM for human SST1-SST5 receptors expressed in CCL39 cells).[1],[2] It is expressed in GABAergic interneurons in the cortex and hippocampus.[2],[3] Cortistatin-14 competitively inhibits hexarelin binding to human growth hormone secretagogue receptors (GHS-R) in pituitary membranes (Ki = 0.54 μM).[4] It also activates the human Mas-related gene receptor MrgX2 expressed in HEK293 cells leading to quantifiable GTP-γS binding to the G protein subunit Gαο (EC50 = 1.3 μM).[5] Cortistatin-14 (0.01-1 μM), similarly to somatostatin-14, completely inhibits thyrotropin-releasing hormone, and partially inhibits vasoactive intestinal peptide, stimulation of cAMP production in GH4 cells.3 In mice, cortistatin-14 dose-dependently (0.05-5 μg, i.c.v.) impairs memory retention when administered after foot shock avoidance training.[6] Cortistatin-14 (40-320 μg/kg, s.c.) dose-dependently reduces growth hormone secretion in rats by greater than 80% after 10 minutes when administered at doses of 40-320 µg/kg.[7]

General tips | Please select the appropriate solvent to prepare the stock solution according to the
solubility of the product in different solvents; once the solution is prepared, please store it in
separate packages to avoid product failure caused by repeated freezing and thawing.Storage method
and period of the stock solution: When stored at -80°C, please use it within 6 months; when stored
at -20°C, please use it within 1 month. To increase solubility, heat the tube to 37°C and then oscillate in an ultrasonic bath for some time. |
