Peptide YY (PYY) is an anorexigenic gut hormone expressed predominantly in the intestinal L-cells.作者：RL Batterham·2003·被引用次数：2178—The gut hormone fragment peptide YY3–36 (PYY)reduces appetite and food intakewhen infused into subjects of normal weight. In common with the adipocyte hormone ... It belongs to the neuropeptide Y (NPY) family of peptides and shares structural homology with NPY and pancreatic polypeptide有研究表明，在大鼠体内外周注射Peptide YY(3-36) 可以抑制食物的摄取，减少体重的增加。Peptide YY(3-36) (human) 是一种内源性食欲抑制肽。. PYY exists in several forms, with PYY(1-36) and PYY(3-36) being prominent. The 3-36 designation refers to a specific cleavage product of the full-length PYY peptide.作者：RE Steinert·2010·被引用次数：108—The results show a marked effect of orally administered GLP-1 and PYY3-36on appetite by showing enhanced fullness at meal onset and reduced energy intake. This shorter form, PYY 3-36, is considered the primary biologically active circulating form responsible for many of its observed effects.

Research indicates that PYY(1-36) and PYY(3-36) cross the blood-brain barrier and participate in appetite and weight control regulation.Peptide YY (3-36) - DrugBank Specifically, PYY (3-36) selectively binds to Y2 receptors, acting as a potent Y2 selective agonist. This selectivity is crucial to its function. Studies have demonstrated that the IC50 values for inhibition of ¹²⁵I-PYY binding to Y2 and Y1 receptors are 0.11 and 1050 nM, respectively, highlighting its preference for the Y2 receptor. This selective binding is a key aspect of its mechanism of action, differentiating it from other PYY forms.Peptide YY (3-36) (trifluoroacetate salt)

Mechanism of Action and Appetite Regulation

The primary role of PYY 3-36 is to signal satiety and reduce food intake.... Y family of receptors.Peptide YY3-36(PYY) is a linear polypeptide consisting of 34 amino acids with structural homology to NPY and pancreatic polypeptide. It is released from the gastrointestinal tract postprandially, meaning after meal ingestion, in proportion to the calorie content of a mealPeptide YY(1-36) and peptide YY(3-36): Part I. Distribution, .... This hormonal signal travels through the bloodstream to the brain, where it interacts with specific receptors, predominantly the Y2 receptors in the arcuate nucleus of the hypothalamusPeptide YY - Wikipedia.

By activating these Y2 receptors, PYY 3-36 inhibits the activity of pro-opiomelanocortin (POMC) neurons and stimulates neuropeptide Y (NPY) neurons, ultimately leading to a reduction in appetite and food intake满2000送100元京东卡 ; 英文名称,Peptide YY(PYY) (3-36)， Human ; 分子式, C180H279N53O ; 分子量, 4049.45 ; 纯度, ≥98% ; 外观(性状), Solid.. This effect has been consistently observed in various studies2005年11月1日—Peptide YY(3–36) [PYY(3–36)]is a hormone that is released after meal ingestionthat is currently being investigated for the treatment of .... For instance, intravenous infusions of PYY3-36 decrease spontaneous food intake.

Further studies have shown that PYY 3-36 inhibits morning, but not evening, food intake, suggesting a potential diurnal rhythm in its effectiveness.Peptide YY [3-36] - an overview Moreover, PYY3-36 and glucagon-like peptide-1 (GLP-1) may inhibit appetite additively in rodents and man, indicating a potential synergistic effect when combined with other appetite-regulating hormones. This suggests that PYY3-36 may be more effective for the treatment of relapse to maladaptive eating behaviors, particularly when considering high-fat food intake.

Therapeutic Potential and Research Applications

The potent appetite-suppressing effects of PYY 3-36 have positioned it as a promising candidate for the treatment of obesity. It is recognized as a compound being evaluated for the treatment of obesity. Research has explored its efficacy in various obesity models, including ob/ob mice and diet-induced obese mice, where it has been associated with dose-dependent weight loss.

In human studies, infusion of PYY(3-36) in humans significantly decreased appetite and reduced food intake by 33% over 24 hours, underscoring its potential as a weight management tool. The compound is also being investigated for its role in regulating satiety.作者：L Degen·2005·被引用次数：489—Background & Aims: Studies in animals and humans suggest a role forpeptide YY (PYY3–36) in regulating satiety. The physiologic role of PYY3–36, however, ... Studies suggest a role for peptide YY (PYY3–36) in regulating satiety, acting as a hormonal signal from the gut to the brain to inhibit food intake.

Beyond obesity, PYY 3-36 is also being researched for its role in gastrointestinal diseases. Its influence on gut motility and electrolyte secretion, where PYY 3-36 inhibits gastrointestinal motility and electrolyte secretion, is an area of ongoing investigation.
