Sincalide
Based on 4 publication(s) in Google Scholar
Sincalide (Cholecystokinin octapeptide, CCK-8) is a rapid-acting amino acid polypeptide hormone analogue of cholecystokinin (CCK) for intravenous use in postevacuation cholecystography. Sincalide is a major bioactive segment of CCK that retains most of the biological activities of CCK. Sincalide can promote gallbladder contraction by injection and helps diagnose gallbladder and pancreas disorders. Sincalide can increase bile secretion, cause the gallbladder to contract and relax the sphincter of Oddi, resulting in bile drainage into the duodenum. Sincalide is a major bioactive segment of CCK that retains most of the biological activities of CCK.

Sincalide (Cholecystokinin octapeptide, CCK-8), as a novel cardiovascular hormone, has a significant inhibitory effect on myocardial fibrosis in noninfarcted areas. Sincalide also plays a positive role in fighting inflammation, apoptosis and collagen deposition. Sincalide protects H9c2 cardiomyoblasts from Ang II-induced apoptosis partly via activation of the CCK1 receptor and the phosphatidyqinositol-3 kinase/protein kinase B (PI3K/Akt) signaling pathway[3].
