Neuropeptide Y, porcine

Neuropeptide Y (porcine), a peptide found in the porcine brain, effectively inhibits secretin-stimulated pancreatic secretion [1].

Neuropeptide Y, porcine TFA, a peptide found in the pig's brain, effectively inhibits secretin-stimulated pancreatic secretion [1].

High affinity neuropeptide Y Y1 receptor agonist

Neuropeptide Y (3-36) (porcine) acts as an agonist for the Y2 subtype of the neuropeptide Y (NPY) receptor, effectively stimulating feeding behavior in rats. This compound exhibits high selectivity for the Y2 receptor compared to the non-selective Y1 Y2 receptor ligand, Neuropeptide Y 1-36 [1][2][3].

Neuropeptide Y (2-36) (porcine) is a pig-sourced peptide closely resembling its rat and human counterparts with 97.14% homology. It acts as an agonist for rat neuropeptide receptors Y5, Y2, and Y1, with EC50 values of 1.2, 1.6, and 3.4 nM, respectively. This compound is utilized in research on obesity and eating disorders [1].

Neuropeptide Y (18-36) (porcine) acts as a competitive antagonist of the neuropeptide Y (NPY) cardiac receptor, blocking I-NPY attachment to cardiac ventricular membranes. Its concentration-dependent action has an IC50 value of 158 nM and a Ki value of 140 nM. This compound is utilized in studying congestive heart failure [1].

Neuropeptide Y (NPY), a neuropeptide, plays roles in regulating appetite, vasoconstriction, cardiac contractility, and intestinal secretion, acting as an agonist for NPY receptors Y1, Y2, and Y5. Expressed ubiquitously, NPY modulates cellular responses by selectively inhibiting forskolin-induced cAMP accumulation in L-M(TK-) cells expressing rat Y1 or Y2 and in HEK293 cells expressing rat Y5, more so than in cells expressing rat Y4 receptors (EC50s = 0.15, 2.7, 0.66, and >1,000 nM, respectively). Additionally, it elevates perfusion pressure in isolated guinea pig hearts (EC30 = 1.3 nM) and, when administered intracerebroventricularly at 300 pmol/animal, it notably increases food intake in rats.

Peptide YY (PYY) (3-36), human (Peptide YY (3-36)), is a gut hormone peptide that acts as a Y2 receptor agonist to reduce appetite.

Galanin (1-16), mouse, porcine, rat, is a hippocampal galanin receptor agonist (Kd = 3 nM) exhibiting high biological activity on locus coeruleus neurons.
