Ceruletide 是一种十肽，也是一种有效的胆囊收缩素受体 (cholecystokinin receptor) 激动剂。 Ceruletide 是一种安全有效的胆囊收缩剂，对胆囊肌肉和胆管有直接的痉挛性作用。
氨基酸序列为：Glp-Gln-Asp-Tyr(SO3H)-Thr-Gly-Trp-Met-Asp-Phe-NH2
序列-Sequence：{pGlu}-Gln-Asp-Tyr(SO3H)-Thr-Gly-Trp-Met-Asp-Phe-NH2
短序列-Sequence Short：{pGlu}-QD-Y(SO3H)-TGWMDF-NH2
Ceruletide Ammonium Salt 具有镇静活性，可用于研究慢性精神分裂症。本品仅用于科学研究。
体外活性
Ceruletide Ammonium Salt 与人类的胃肠激素胆囊收缩素（CCK）和胃泌素II具有化学和生物学上的相似性。该化合物促进胆囊收缩、胰腺外分泌、胃液分泌以及远端十二指肠、空肠、回肠和结肠的蠕动，同时延迟胃排空并抑制近端十二指肠的蠕动。在体外，Ceruletide Ammonium Salt 在超生理剂量而非生理水平激活NF-kappaB/Rel。此激活可能在细胞损伤发生前诱导自我保护性的遗传程序，有潜力在胰腺泡沫细胞受到过度刺激剂刺激后防止更高程度的损伤。
体内活性
Ceruletide Ammonium Salt 可用于动物模型的构建，特别是在构建胰腺炎的动物模型上。Ceruletide Ammonium Salt（0.4-0.5 μg/kg, 静脉注射；3-4 μg/kg, 皮下注射）在狗体内能引发清醒且完整的呕吐与排便，分别在静脉注射后15-30分钟及皮下注射后2-4小时内完全恢复。Ceruletide Ammonium Salt（5-15 ng/kg, 静脉注射）在大鼠体内显著促进幽门痉挛。此外，Ceruletide Ammonium Salt还能降低麻醉狗的血压。Ceruletide Ammonium Salt刺激的血清胆汁酸（SBA）逃逸，消除了与餐后（PP）SBA刺激相关的外源性和内源性影响。对于患有门体分流（PSS）的狗，Ceruletide Ammonium Salt刺激的SBA可能与PP SBA刺激同样有效，并且在检测患有上呼吸道疾病（URD）的狗的肝功能障碍方面可能更为敏感。
Ceruletide is a decapeptide and a potent Cholecystokinin Receptor agonist. Ceruletide is a safe and effective cholecystokinetic agent with a direct spasmogenic effect on the gallbladder muscle and bile ducts.
In vitro activity
Ceruletide Ammonium Salt shares chemical and biological similarities with the gastrointestinal hormones cholecystokinin (CCK) and gastrin II in humans. Ceruletide Ammonium Salt stimulates gallbladder contraction, pancreatic exocrine secretion, gastric fluid secretion, and motility in the distal duodenum, jejunum, ileum, and colon, while delaying gastric emptying and inhibiting motility in the proximal duodenum. In vitro, Ceruletide Ammonium Salt activates NF-kappaB/Rel at supraphysiological doses rather than at physiological levels. This activation may induce a self-protective genetic program before cell damage occurs, potentially preventing a higher degree of injury to pancreatic acinar cells after excessive stimulation by secretagogues.
In vivo activity
Ceruletide Ammonium Salt can be utilized for animal modeling, specifically in constructing animal models of pancreatitis.
Ceruletide Ammonium Salt (0.4-0.5 μg/kg, intravenous injection; 3-4 μg/kg, subcutaneous injection) induces conscious and complete vomiting and defecation in dogs, with full recovery observed 15-30 minutes and 2-4 hours after intravenous administration or subcutaneous injection, respectively. Ceruletide Ammonium Salt (5-15 ng/kg, intravenous) demonstrates a significant spasmogenic effect on the pylorus in rats. Additionally, Ceruletide Ammonium Salt can reduce blood pressure in anesthetized dogs.
Ceruletide Ammonium Salt-stimulated serum bile acids (SBA) evasion eliminates exogenous and endogenous influences associated with postprandial (PP) SBA stimulation. The effectiveness of Ceruletide Ammonium Salt-stimulated SBA in dogs with portosystemic shunts (PSS) may be as good as PP SBA stimulation, and it may be more sensitive in detecting hepatic dysfunction in dogs with upper respiratory disease .
