Talogreptide mesaroxetan (CAS 1801418-23-4) is a synthetic peptide, a complex molecule used as a diagnostic imaging agent with potential antitumor effects, targeting G-protein coupled receptors (GRPr) often overexpressed in cancers, allowing for specific tumor visualization in PET scans, particularly for metastatic disease detection, known for its high specificity and contrast for imaging tumors like those expressing GRPr.
Key Characteristics:
- Type: A peptide-based diagnostic agent, often labeled with radioisotopes like Copper-64 ($^{64}$Cu) for Positron Emission Tomography (PET) imaging, notes Patsnap Synapse.
- Structure: It’s a modified peptide sequence incorporating elements like PEG4 and specific amino acids, MedchemExpress.com.
- Function: Binds strongly to GRPr, helping to highlight tumors and metastatic sites.
- Application: Used in research to create high-contrast PET scans for better tumor detection and monitoring, showing promise in visualizing lymph node metastasis.
In Simple Terms:
Imagine it as a “smart tracer” that seeks out specific cancer cells. When attached to a radioactive tag, it lights up tumors on a PET scan, helping doctors see cancer more clearly, notes Patsnap Synapse.
