Abstract

The selection of precursors (for example chelating agents) and development of a technique of chemical modification of the target molecules retaining its ability to bind to specific receptors are very important in the synthesis of radiopharmaceuticals. As some important precursors for target radiopharmaceuticals omega-iodo-aliphatic carboxylic acids and their esters can be used. We have developed an environmentally safe process for producing omega-iodo-aliphatic carboxylic acids and their esters of the available, inexpensive and low toxic aliphatic cyclic ketones. We proposed a new method for the synthesis of the chelating agents omega-thia- or (bis(2-hydroxyethyl)amino)- aliphatic carboxylic acids (chelate 1 and chelate 2), which was caused by the existing disadvantages in the existing methods. Thus, based on our method the precursors (chelates) with yield of over 70-90% on the final stage were synthesized, and then the high effectiveness in producing target radiopharmaceuticals using different biomolecules was showed. 99mTc-chelates complexes were prepared with radiochemical purity >91% and found to be stable at room temperature for six hours.
