Sincalide(CCK-8) is a minor bioactive segment of CCK that retains most of the biological activities of CCK and is widely used to study CCK functions[1]. Sincalide is a rapid-acting, synthetic analog of cholecystokinin for intravenous use in postevacuation cholecystography, and has a variety of effects as a novel cardiovascular hormone[2,3].
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[1]. Sincalide can protect human retinal pigment epithelial cells against apoptosis induced by peroxynitrite[4]. Sincalide dose-dependently inhibited METH-induced cytotoxic effect by activating the CCK2 receptor subtype in PC12 cells and CCK2 receptor stable transfected-HEK293 cells[5]
Sincalide can alleviate fibrosis in the noninfarcted regions and delay the left ventricular remodeling and the progress of heart failure in a MI rat model[2]. Sincalide decreased RPE cells apoptosis partly induced by ONOO- in Sprague-Dawley rats and is a potential drug for therapy of diabetic retinopathy[6]. Intramuscular injection of sincalide (0.07μg/kg) induced remarkable contractions of the gallbladder in vivo, and the contraction was nearly abolished by premedication of atropine sulfate (0.015 mg/kg)[7]
