SMILES: O=C([C@@H](NC([C@H](CSSC[C@H](NC([C@](NC([C@@H](NC1=O)CCCCN)=O)([H])[C@H](O)C)=O)C(N[C@H](C(O)=O)[C@H](O)C)=O)NC([C@H](N)CC2=CC=CC=C2)=O)=O)CC3=CC=C(C=C3)O)N[C@@H]1CC4=CNC5=CC=CC=C45
Biological Activity: Tyr3-Octreotate is a ligand for somatostatin receptor subtype 2 (sst2), with an IC50 value of 1.3 nM against sst2 when labeled with [111In-DTPA], and an IC50 value of 1.6 nM against sst2 when labeled with [90Y-DOTA]. Radiolabeled Tyr3-Octreotate generates cell-associated radioactivity, and acts as both a tumor growth inhibitor and a tumor cytotoxic agent. When radiolabeled with 177Lu or 90Y, Tyr3-Octreotate serves as a peptide receptor radionuclide therapy (PRRT) analog. Tyr3-Octreotate can be used in studies related to pancreatic tumors[1].
