Retatrutidepeptide Peptide R is a specialized cyclic peptide recognized for its potent activity as a CXCR4 antagonist. This specific function allows Peptide R to significantly influence the tumor microenvironment, demonstrating capacities to remodel the stromaStorage: Up to 6 months in lyophilized form at 0-5°C. For best results, rehydrate just before use. After rehydration, keep solution at +4°C for up to 5 days .... While the term "Peptide R" might also appear in contexts related to research chemicals, particularly concerning Retatrutide, its primary scientific identity lies in its role as a CXCR4 inhibitorPeptide-R 50mg vial in lyophilized powder form. Must be reconstituted with bacteriostatic water prior to use (NOT INCLUDED). Once reconstituted, shelf life .... Understanding this distinction is crucial, especially when encountering "Peptide R" in scientific literature or chemical supply contexts.

The CXCR4 Antagonist Function of Peptide R

At its core, Peptide R functions by blocking the CXCR4 receptor.In the present study, we evaluated the effects of peptide R,a new specific CXCR4 antagonistthat we recently developed by a li... Cite · Download full-text ... CXCR4 is a chemokine receptor that plays a vital role in various cellular processes, including immune cell trafficking, stem cell migration, and importantly, cancer progression. By antagonizing CXCR4, Peptide R can interfere with these processes. Research indicates that Peptide R has shown promise in preclinical studies for its ability to modify the tumor stroma, a complex network of cells and extracellular matrix that supports tumor growth and metastasis. This stroma remodeling capability is a key area of interest for its potential therapeutic applications in oncologyRetatrutide for Weight Loss: Availability, Dosage, and More.

Distinguishing Peptide R from Retatrutide

It is essential to differentiate Peptide R from Retatrutide, a peptide drug that has gained attention for its application in weight loss and the management of type 2 diabetes and fatty liver disease2025年12月11日—Retatrutide is a triple hormone (GIP, GLP-1 and glucagon) receptor agonist in development for the treatment of obesity.. While both are peptides, their biological targets and intended uses are entirely different.Peptides & Amino Acids for Beginners: Understanding the ... Retatrutide is a triple hormone receptor agonist, targeting GIP, GLP-1, and glucagon receptors, thereby influencing appetite, energy expenditure, and glucose metabolism. In contrast, Peptide R is a CXCR4 antagonist, primarily investigated for its effects on the tumor microenvironment. The confusion may arise because "Peptide-R" or similar nomenclature can sometimes be used in research supply contexts for various peptides, including those related to Retatrutide research.作者：L Wang·2022·被引用次数：2124—Therapeutic peptides area unique class of pharmaceutical agentscomposed of a series of well-ordered amino acids, usually with molecular ...

Chemical Properties and Research Applications

Peptide R is a cyclic peptide with a molecular weight of approximately 902.1 g/mol and a chemical formula of C39H59N13O8S2Peptides: What are they, uses, and side effects. It is often supplied in a lyophilized form, meaning it has been freeze-dried for stability and requires reconstitution before use. For optimal results in laboratory settings, it is typically stored at 0-5°C in its lyophilized state and should be rehydrated just before application, with reconstituted solutions stable for up to five days at +4°C. These specifications are common for peptides intended for research and assay development, highlighting its role as a tool in scientific investigation rather than a direct therapeutic agent for widespread clinical use in its current form.

Broader Context of Peptides

Peptides themselves are fundamental biological molecules, consisting of short chains of amino acids linked by peptide bondsWhat Is Retatrutide? Everything You Need To Know. They are essentially smaller versions of proteins and play diverse roles in the body, acting as signaling molecules, hormones, and neurotransmittersTop 9 Peptides for Athletic Performance and Strength Gains. Their small size and specific structures allow them to interact with cellular targets, influencing processes such as cell proliferation, tissue repair, and immune responses. This broad category of peptides encompasses a vast range of compounds, from naturally occurring hormones to synthetic therapeutic agents and research tools, making it crucial to specify the exact peptide of interest, such as Peptide R, to understand its unique properties and applications.
