HIDE SMILES / InChI

Description

Dotatate, also known as DOTA-0-Tyr3-Octreotate, is a cyclic 8 amino acid peptide with a covalently bound chelator (dota). The peptide has the amino acid sequence: H-D-Phe-Cys-Tyr-D-Trp-Lys-ThrCys-Thr-OH, and contains one disulfide bond. After radiolabeling with Ga 68 (NETSPOT®) or with Lu 177 (LUTATHERA®), it is indicated for use with positron emission tomography (PET) for localization of somatostatin receptor positive neuroendocrine tumors (NETs) in adult and pediatric patients.
