Stability of the complex was checked in final formulation and in the presence of human serum for 48 h. The partition coefficient was calculated for the compound (log P=0.68).Results: The biodistribution of the labeled compound in vital organs of wild-type rats was studied using scarification studies and SPECT up to 24 h. A detailed comparative pharmacokinetic study for 111In cation and 111In-HMQ are performed up to 24h.Conclusion: The complex is mostly cleaned from the circulation by kidneys and is a compound rapidly washing from the circulation. The biodistribution of the complex in tumor models is on-going. %K 8-Hydroxy-2-methylquinoline %K In-111 %K Biodistribution %K SPECT %U rjnm.tums.ac.ir/index.php/irjnm/article/view/706/663
