Cyclic somatostatin  (Synonyms: SRIF-14; Somatostatin-14)

Cat. No.: HY-P0084 Purity: 99.77%
COA Handling Instructions

Cyclic somatostatin (SRIF-14) is a growth hormone-release inhibiting factor used in the treatment 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.

Description

Cyclic somatostatin (SRIF-14) is a growth hormone-release inhibiting factor used in the treatment 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[1][2][3].

IC50 & Target

IC50: 13 nM (contractile response of isoprenaline)[1]

In Vitro

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[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

Cyclic somatostatin (5 μg/kg; i.v. per hour once for 18-22 hours) affects visceral metabolism in ruminants[3].

Animal Model: Polypay sheeps[3]
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.
