DOTA-TATE
DOTA-TATE, DOTATATE or DOTA-octreotate is a substance which, when bound to various radionuclides, has been tested for the treatment and diagnosis of certain types of cancer, mainly neuroendocrine tumours. ==Chemistry and mechanism of action== DOTA-TATE is an amide of the acid DOTA (top left in the image), which acts as a chelator for a radionuclide, and (Tyr3)-octreotate, a derivative of octreotide. The latter binds to somatostatin receptors, which are found on the cell surfaces of a number of neuroendocrine tumours, and thus directs the radioactivity into the tumour.
