Incretin mimetics The S597 peptide is a synthetic insulin mimetic that targets the insulin receptor (IR).作者：J Park·2022·被引用次数：36—A previously reported selective IR agonist without sequence homology to insulin,S597, activates IR and mimics insulin's action on glycemic control. Research indicates that S597, a 31-amino acid peptide, activates the IR by phosphorylating it, mimicking some of insulin's actions on glycemic control. Unlike insulin, S597 does not share sequence homology with insulin, yet it can activate insulin binding-deficient IR mutants and those causing severe insulin resistance syndromes.作者：H Rajapaksha·2015·被引用次数：40—The first is aninsulin agonist peptide selected by phage display (S597) that binds the IR-A with equal affinity to insulin and yet does not activate mitogenic ... This peptide has shown potential in preclinical studies to reduce high blood sugar levels.
S597 functions as an agonist for the insulin receptor. Studies utilizing Cryo-EM structures have detailed how the S597 peptide binds to the insulin receptor, promoting its activation.2019年6月1日—The List of Prohibited Substances and Methods (List) indicates what substances and methods are prohibited in sport and when. While it phosphorylates the insulin receptor similarly to insulin, it does so to a lesser degree作者：J Park·2022·被引用次数：36—A previously reported selective IR agonist without sequence homology to insulin,S597, activates IR and mimics insulin's action on glycemic control.. This selective activation means S597 can elicit insulin-like effects on glycemic control without necessarily triggering all downstream pathways that insulin does, particularly those related to mitogenesis2018年2月28日—A peptide called S597, given to mice with metabolic syndrome,reduced their high blood sugar levelsand slowed the growth of lesions in their .... This differential activity is a key area of research, with some studies suggesting S597's binding does not activate mitogenic signaling to the same extent as insulinCryo-EM structure of insulin receptor (IR) bound with S597 ....
The S597 peptide has been a subject of significant scientific investigation. Its development as an insulin mimetic aims to explore new therapeutic avenues for conditions related to insulin resistance and diabetes.2019年6月1日—The List of Prohibited Substances and Methods (List) indicates what substances and methods are prohibited in sport and when. Researchers have synthesized and evaluated analogs of S597, sometimes modifying its structure with alternative linkages or substitutions to fine-tune its properties. These efforts contribute to understanding ligand-receptor interactions and developing more targeted peptide therapeutics.
Beyond its potential therapeutic applications, S597 has also garnered attention in sports drug testing. Assays have been developed for the reliable detection of insulin-mimetic peptides like S597 in biological samples, such as plasma. These detection methods are crucial for ensuring fair play in sports, as substances that can affect glucose metabolism could potentially be misused for performance enhancement.
The ongoing research into S597 peptide, including its structural characterization through techniques like mass spectrometry, continues to shed light on its precise interactions with the insulin receptorCryo-EM structure of insulin receptor (IR) bound with S597 .... While S597 demonstrates promising insulin-mimetic properties and potential for therapeutic use in managing blood glucose, further research is necessary to fully elucidate its long-term effects, safety profile, and efficacy in clinical settings.InsR peptide agonist (S597) Its ability to activate specific IR mutants and its distinct signaling profile compared to insulin suggest a nuanced role in future diabetes management strategies.
