pt 161 peptide ATN 161 is a α5β1 integrin receptor antagonist

Published October Oct 18, 2026 5:25 AM

When exploring advanced biochemical research, one frequently encounters the term pt 161 peptide, often conflated with various synthetic compounds in literature. It is essential to clarify that in scientific databases, the primary subject of interest is ATN-161, a well-documented five-amino acid peptide that serves as a focal point for researchers stu ATN 161 | Integrin Receptor Inhibitors: Tocris Bioscience dying cell signaling and rece SHBG141–161 is a peptide corresponding to amino acids 141–161 of sex hormone binding globulin (SHBG), the loop region of SHBG connecting β-strands 11 and 12. ptor dynamics.

The Biochemical Profile of ATN-161

ATN-161 is a non-RGD based integrin binding peptide derived from the synergy region of fibronectin. Its chemical structure, often noted as A by X Lv · 2019 · Cited by 19 — ATN-161 (Ac-PHSCN-NH2) is a small peptide antagonist of integrin α5β1, a recently developed anticancer drug that interacts with the N-terminus of the β1 region  c-PHSCN-NH2, makes it a specialized tool for laboratory investigations. Unlike standard RGD motifs, this small peptide antagonist of integrin alpha5beta1 interacts specifically with the N-terminus of the beta-1 region, which is a critical area of focus for those analyzing angiogenesis and cellular migration.

As someone who tracks peptide research, I find the specificity of the PHSCN peptide (licensed as ATN-161) to be particularly fascinating. It acts as an alpha v beta 1 inhibitor and is recognized ATN-161 reduces virus proliferation in PHEV-infected mice as a novel integrin alpha5beta1 antagonist. Because it selectively binds to and blocks the receptor for integrin, it has been a frequent subject in studies regarding the inhibition of tumor growth, angiogenesis, and metastasis.

E-E-A-T and Research Integrity

When reviewing data on The Integrin Binding Peptide, ATN-161, it is vital to rely on peer-reviewed literature and high-quality chemical suppliers. Many of the studies Product Description. ATN 161 is a α5β1 integrin receptor antagonist. Reduces liver metastasis and improves survival in combination with 5-FU (Cat. No. cited in academic repositories, such as PubMed, underscore the importance of purity and structural integrity in these compounds. Whether you are looking at the Bcl-2-like protein 11 142-161 or the SHBG141–161 peptide, the nomenclature can be confusing. However, ATN 161 is a α5β1 integrin receptor antagonist that remains distinct from other epitope markers.

Key Technical Specifications

* Molecular Composition: Five-amino acid sequence (Ac-PHSCN-NH2).

* Primary Function: Integrin receptor antagonism (specifically α5β1 and αvβ3).

* Research Application: Investigated for antiangiogenic properties and cell adhesion inhibition.

ATN-161 Peptide Functionalized Reversibly Cross-Linked

* Synthesis: Often produced via squaric acid-mediated synthesis in ATN-161 peptide functionalized reversibly crosslinked materials.

Observations on Experimental Use

In my experience analyzing laboratory reports, the distinction between ATN-161 and other compounds with "161" in their name—such as Tb-161 (a radionuclide) or MAGE-1 Antigen (161-169)—is paramount. A Phase 1 Trial of the Antiangiogenic Peptide ATN-161 highlighted its potential in modulating biological pathways, yet it is crucial to remember that these are strictly for controlled research environments.

The Integrin-bindi ATN 161 has been shown to inhibit tumour growth, angiogenesis and metastasis and extend survival in multiple animal tumours, it has also shown activity outside  ng peptide ATN-161 is frequently utilized in murine models to evaluate its capacity to reduce liver metastasis. Its role as a non-competitive inhibitor of the fibronectin synergy site is what sets it apart from traditional antagonists.

Conclusion

Whether you are a student of biochemistry or a researcher focusing on cellular signaling, understanding the nuance of ATN-161 is key. It is not merely a number; it is a meticulously designed five amino acid peptide, ATN 161, that provides significant value in the study of integrin-mediated processes. Always ensure that when sourcing these materials, you prioritize suppliers who provide comprehensive HPLC analysis to confirm the identity and purity of the peptide. By focusing on the verified mechanisms of this small peptide antagonist of integrin alpha5beta1, we can better appreciate the complex nature of protein-protein interactions in experimental settings.
