生物活性:
Cyclic somatostatin (SRIF-14) is a growth hormone-release inhibiting factor used in the research of severe, acute hemorrhages of gastroduodenal ulcers. Cyclic somatostatin is a neuropeptide co-stored with acetylcholine in the cardiac parasympathetic innervation, exerts influences directly on contraction of ventricular cardiomyocytes. Cyclic somatostatin inhibits the contractile response of isoprenaline with an IC50 value of 13 nM. Cyclic somatostatin can be used for the research of cardiovascular disease.
体内研究:
Cyclic somatostatin (5 μg/kg; i.v. per hour once for 18-22 hours) affects visceral metabolism in ruminants.Animal Model:Polypay sheeps
Dosage:5 μg/kg
Administration:Intravenous injection; 5 μg/kg per hour once; for 18-22 hours
Result:Decreased net portal-drained viscera release of glucose, a-amino N, ammonia N, b-hydrox ybutyrate, oxygen consumption, liver oxygen consumption, and total splanchnic a-amino N release and oxygen consumption. Increased lactate release and net hepatic glucose output.
体外研究:
Cyclic somatostatin (0-10 μM; 15 min) dose-dependently inhibits the contractile response to isoprenaline in rat ventricular cardiomyocytes with an IC50 value of? 13 nM.
