A Trithiol Bifunctional Chelate for 72,77As: a Matched Pair Theranostic Complex with High in vivo Stability

Trithiol chelates are suitable for labeling radioarsenic (72As: 2.49 MeV β+, 26 h; 77As: 0.683 MeV β−, 38.8 h) to form potential theranostic radiopharmaceuticals for PET imaging and therapy. To investigate the in vivo stability of trithiol chelates complexed with no carrier added (nca) radioarsenic, a bifunctional trithiol chelate was developed, and conjugated to bom besin(7-14)NH2 as a model peptide.
