Edotreotide

Edotreotide is a ligand that selectively targets SSTR2 and can competitively bind to the receptor. Edotreotide mediates the targeted delivery, while modificated with radionuclides (such as 90Y, 177Lu, and 68Ga) to SSTR-positive tumors and induces tumor cell apoptosis by releasing β rays. Edotreotide has strong tumor targeting and precise killing activity. Edotreotide is used in the synthesis of radionuclide-drug conjugates (RDCs) and is widely used in the field of neuroendocrine tumors (such as metastatic carcinoids, lung and thymus NETs) [1][2][3].
