Neuropeptide Y (NPY) (3-36) is a C-terminal fragment of NPY, a neuropeptide involved in controlling appetite, blood pressure, cardiac contractility, and intestinal secretion. NPY (3-36) is an endogenous peptide produced by cleavage of NPY by dipeptidyl peptidase 4 (DPP-4). It binds selectively to the NPY receptor Y2 (Ki = 0.41 nM in CHP 234 cells) over the Y1 receptor, where it does not bind at concentrations up to 1 μM. NPY (3-36) (0.1 nM) increases migration of human umbilical vein endothelial cells (HUVECs) by 80% after 12 hours in an in vitro wound closure assay. NPY (3-36) corresponds to residues 3-36 of the human and rat protein sequence.

Neuropeptide Y (3-36) (human, rat) is a metabolite of neuropeptide Y (NPY) generated by dipeptidyl peptidase-4 (DPP4) and is known as a selective Y2 receptor agonist, effectively reducing the release of norepinephrine via the Y2 receptor [1][2].

[D-Trp34]-Neuropeptide Y TFA is a potent and selective agonist for the neuropeptide Y (NPY) Y5 receptor, demonstrating significantly lower potency at the NPY Y1, Y2, Y4, and Y6 receptors. It significantly increases food intake in rats [1] [2].

[Leu31,Pro34]-Neuropeptide Y(human,rat) TFA acts as a specific agonist for the neuropeptide Y Y1 receptor and also activates Y4 and Y5 receptors, elevating blood pressure in anesthetized rats and enhancing food intake [1] [2].

Neuropeptide S(Mouse) TFA, an endogenous agonist for the neuropeptide S receptor (NPSR) with an EC50 value of 3 nM, plays a significant role in physiological processes by inducing the mobilization of intracellular Ca2+. This compound elevates locomotor activity and wakefulness, and simultaneously decreases anxiety-like behavior in mice.

Neuropeptide S(Rat) TFA, a robust endogenous agonist for the neuropeptide S receptor (NSPR) with an EC50 of 3.2 nM, enhances locomotor activity and promotes wakefulness while concurrently diminishing anxiety-like behavior in mice.

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 (1-24) (human) is a neuropeptide that inhibits electrically stimulated twitch responses in rat vas deferens and activates neurons in the rat CA3 region of the dorsal hippocampus in vivo following N-methyl-D-aspartate (NMDA) induction [1] [2].

Neuropeptide AF (cattle), an amidated octadecapeptide and RFamide neuropeptide, serves as a ligand for Mas-related gene receptor A4 (MrgprA4) (Mas-related G-protein-coupled Receptor (MRGPR)) with an EC50 of approximately 60 nM, and MrgprC11 with an EC50 of around 300 nM. It activates G protein-coupled receptors NPFF1 (Neuropeptide Y Receptor) with an EC50 ranging from ~25 to 325 nM, and NPFF2 with an EC50 of approximately 1 to 5 nM.
