Task: Answer the following question about the molecule with SMILES CC(O)(OP(=O)([O-])[O-])OP(=O)([O-])[O-].[186Re].
Request: Please describe this drug.
Answer: Rhenium Re 186 Etidronate is an synthetic compound containing the organic phosphonate hydroxyethylidene diphosphonate (HEDP) labeled with the radioisotope rhenium Re 186. Re-186 etidronate binds to hydroxyapatite in bone, delivering a cytotoxic dose of beta radiation to primary and metastatic bone tumors. Re-186 is a beta emitter with a short half-life, a radioisotope profile that provides localized antitumor radiocytotoxicity while sparing extramedullary bone marrow tissues.
