Preparation and quality control of 177Lu-[tris(1,10-phenanthroline) lutetium(III)] complex for therapy
Nucl. Med. Rev 2010;13(2):49-54.
Abstract
The 177Lu-[tris(1,10-phenanthroline)lutetium(III)] complex
(177Lu-PQ3) was prepared successfully with high radiochemical
purity (> 99%). Lu-177 chloride was obtained by
thermal neutron flux (4 × 1013 n.cm–2.s–1) of natural Lu2(NO3)3
sample, dissolved in acidic media. The radiochemical yield
was checked by measuring the radiochemical purity of the
177Lu-PQ complex by ITLC (10 mM DTPA, pH = 5, as mobile
phase). The final complex solution was injected intravenously
into wild-type male rats and bio-distribution of the complex
was checked for up to 48 hours. The dose limiting organs
were shown to be the reticulu-endothelial system. The
bio-distribution of the labelled compounds in tumour-bearing
animals is under investigation.
