pentetic acid calcium
The calcium salt of pentetic acid, a synthetic chelating agent related to the chelating agent ethylenediaminetetraacetic acid (EDTA). Pentetic acid chelates with the metallic radioisotopic moieties of unbound, extracellular radioimmunotherapeutic agents, resulting in higher specific tumor cell binding of radioimmunotherpeutic agents; this results in improved tumor cell radiocytotoxicity and the sparing of normal cells and tissues from the radiocytotoxic effects of these agents. Check for active clinical trials using this agent. (NCI Thesaurus)
