neuropeptide y (human)

Neuropeptide Y (human) is a biologically active 36-amino acid peptide.

Neuropeptide Y (human) TFA, a compound implicated in Alzheimer's disease (AD), exhibits protective effects against β-Amyloid toxicity in rat cortical neurons.

[D-Arg25]-Neuropeptide Y (human) ([D-Arg25] NPY), a Y1 receptor selective agonist, is involved in Alzheimer's disease (AD) and protects rat cortical neurons from β-Amyloid toxicity [1].

Neuropeptide Y (human) free acid is the deamidated form of Neuropeptide Y (human, rat, mouse). The amidation of the C-terminal tyrosine in Neuropeptide Y is essential for its function, while the non-amidated form cannot initiate G-protein signaling.

Neuropeptide Y (29-64), amide, human acetate is involved in Alzheimer's disease (AD) and protects rat cortical neurons against β-Amyloid toxicity.

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].

[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 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 Y (13-36), amide, human is a neuropeptide Y receptor agonist.

[D-His26]-Neuropeptide Y, human, rat is a synthetic variant of neuropeptide Y (NPY). This compound acts as a Y1R agonist and may help prevent the development of anxiety, social disorders, and depressive symptoms. It has potential as an early intervention treatment for post-traumatic stress responses.

α-Melanocyte-stimulating hormone (α-MSH) is a 13-amino acid peptide hormone produced by post-translational processing of proopiomelanocortin (POMC) in the pituitary gland, as well as in keratinocytes, astrocytes, monocytes, and gastrointestinal cells.1It is an agonist of melanocortin receptor 3 (MC3R) and MC4R that induces cAMP production in Hepa cells expressing the human receptors (EC50s = 0.16 and 56 nM, respectively).2α-MSH (100 pM) reducesS. aureuscolony formation andC. albicansgerm tube formationin vitro.3It inhibits endotoxin-, ceramide-, TNF-α-, or okadaic acid-induced activation of NF-κB in U937 cells.1α-MSH reduces IL-6- or TNF-α-induced ear edema in mice.4It also prevents the development of adjuvant-induced arthritis in rats and increases survival in a mouse model of septic shock. Increased plasma levels of α-MSH are positively correlated with delayed disease progression and reduced death in patients with HIV.1 1.Catania, A., Airaghi, L., Colombo, G., et al.α-melanocyte-stimulating hormone in normal human physiology and disease statesTrends Endocrinol.
