生物活性:
Apelin-13 is an endogenous ligand for the G-protein coupled receptor angiotensin II protein J (APJ), activating this G protein-coupled receptor with an EC 50 value of 0.37 nM. Apelin-13 is widely distributed in the central and peripheral nervous systems. Apelin-13 has vasodilatory and antihypertensive effects. Apelin-13 also can be used for researching type 2 diabetes and metabolic syndrome.

体内研究:
Apelin-13 (200 μg/kg; IP, daily for 4 weeks) improves cardiac function, improves insulin resistance, improves lipid metabolism, significantly decreases TNF-α and leptin on serum,induces the expression of Apelin-12 in serum and markedly elevates GLUT4 and p-AMPKα2 levels.Apelin-13 (10 and 100 μM; ICV, single dosage) increases the spontaneous discharges in the majority of pallidal neurons.Animal Model:Goto-Kakizaki (GK) rats (12 weeks old; 240-280 g; fed with a high-fat diet: 66.5% standard chow, 10% lard, 20% sucrose, 2.5% cholesterol and 1% pig bile salt)
Dosage:200 μg/kg
Administration:IP, daily for 4 weeks
Result:Significantly decreased heart rate; lowered the levels of fasting plasma glucose (FPG), fasting insulin (FINS) and homeostasis model assessment for insulin resistancey (HOMA-IR); decreased serum levels of total cholesterol (TC), triglyceride (TG) and low density lipoprotein-cholesterol (LDL-C) and increased high density lipoprotein-cholesterol (HDL-C); decreased NO level, cNOS activity, TNF-α and leptin in serum; induced the expression of Apelin-12.
Animal Model:Adult Wistar rats (SPF, 8-10 weeks, 240-280 g)
Dosage:10 and100 μM
Administration:ICV, single dosage
Result:Increased the spontaneous discharges in the majority of pallidal neurons.
