| Description |
Ceruletide (Caerulein) is a biologically active decapeptide isolated from the skin of the Australian frog Hyla caerulea. It is a potent cholecystokinetic agent with a direct spasmogenic effect on the gallbladder muscle and bile ducts in humans and |

| In Vitro |
Ceruletide is similar chemically and biologically to the human gastrointestinal hormones cholecystokinin-pancreozymin (CCK) and gastrin II. Ceruletide stimulates gallbladder contraction, pancreatic exocrine secretion, gastric secretion, and motility in the distal duodenum, jejunum, ileum and colon, while delaying gastric emptying and inhibiting motility in the proximal duodenum[1]. NF-kappaB/Rel is rapidly activated during cerulein pancreatitis. This activation may induce a self-defending genetic program before the onset of cellular injury, which might prevent higher degrees of damage of pancreatic acinar cells after secretagogue hyperstimulation[2]. |
