Abstract:
A method for preparing 99mTc-Dacarbazine, a potential cancer diagnostic agent, was developed. The method is based on direct labeling of Dacarbazine with 99mTc in the presence of stannous chloride as reducing agent. The reaction conditions were optimized to obtain the radiochemical yield of 99mTc-Dacarbazine higher than 90%. The biodistribution of 99mTc-Dacarbazine in normal and tumor-bearing Albino Swiss mice was studied. 99mTc-Dacarbazine has a high tumor affinity and shows promise for cancer imaging. Quantitative relationship between the optimized structures and computed molecular properties related to Dacarbazine binding sites was analyzed using molecular modeling.
