Description
Summary:The aim of this study is the synthesis of a novel .sup.99mTc-labeld graft polymer and the biological evaluation of its in vitro and in vivo properties. To this end, a L-proline-graft-poly(HEMA) was prepared and labeled with .sup.99mTc. The radiochemical yield of approximately the .sup.99mTc-labeled compound amounted to 97 ± 2.3%. The cytotoxicity test revealed no cytotoxic effect after a 24- and 48-h incubation. The results of the hemolysis test showed that hemolysis was non-toxic with an effect level of less than 2%. Subsequently, the biodistribution in healthy rats was determined. High accumulation of the polymer was observed in the pancreas, thyroid and prostate.
