Yttrium (90Y) tacatuzumab tetraxetan (trade name AFP-Cide) is a humanized monoclonal antibody intended for the treatment of cancer.[1] The antibody itself, tacatuzumab, is conjugated with a chelator for yttrium-90[2], a radioisotope which destroys the tumour cells.
The chelator ("tetraxetan") is 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid. The antibody is attached to one of the four carboxyl groups as an amide, and the other three are carboxylate anions neutralizing the three positive charges of the yttrium ion.
