摘要

~105Rh has favorable physical characteristics as a radiotherapeutic nuclide. Carrier-free ~105Rh can be produced by the neutron activation of ~104Ru followed by beta decay of ~105Rh. It was clarified that carrier-free ~105Rh can be produced in quantities and the purity necessary for chemical and clinical investigations of its use as a nuclide for radiotherapy. ~105Rh-EDTMP was simply obtained from ~105Rh~3+ and EDTMP by heating for 30 min in boiling water, giving a radiochemical yield of >99%. Dissociation of radiocactivity assessed by paperchromatography was negligible for up to 5 days after its preparation. In animals, ~105Rh-EDTMP showed rapid blood clearance and selective uptake in the bone. Hence, ~105Rh-EDTMP is thought to be a promising therapeutic agent for the treatment of pain due to bone metastases.
