GRPR-targeting Radioconjugate LY4257529

**Semantic type:** Pharmacologic Substance

**Definition:** A radioconjugate consisting of a gastrin-releasing peptide receptor (GRPR)-targeting ligand, labeled with an undisclosed radioisotope, with potential use in imaging of GRPR-expressing tumor cells. Upon administration, GRPR-targeting radioconjugate LY4257529 targets and binds to GRPR-expressing tumor cells. This allows for specific detection of GRPR-expressing tumor cells upon imaging. GRPR, also called bombesin receptor 2 (BB2), is a G protein-coupled seven-transmembrane receptor belonging to the bombesin receptor family. It is overexpressed in certain types of cancers.
