Synkavit and its direct labelling with iodine-125, as a potential anti-cancer drug.

| Abstract |
The compound known as "synkavit" is a diphosphate derivative of vitamin K3 (menadion), which is capable of being selectively accumulated in certain tumour cells, and covalently bonded to DNA producing considerable DNA damage. On the other hand, iodine-125 nuclide incorporated into the nucleus of living cells causes extreme radiotoxic effects. Consequently, synkavit can be used as a specific carrier of iodine-125 into the nucleus of tumour cells. Thus, its iodo-derivatives have become interesting agents on the potential application of iodine-125 in cancer therapy. 6-Iodo-synkavit is a unique iodo-derivative described in the literature. In addition, its synthesis and radioiodination is still problematic, and consequently the results obtained using 6-iodo-synkavit labelled with iodine-125 remains in question. For this reason, the synthesis of 6-iodo-synkavit was examined in this study. It is finally determined that a mixture of different iodo-isomers of synkavit has been produced rather than its specific 6-iodo-isomer, when the synthetic sequence was begun with the direct sulfonation of 2-methyl-naphthalene. On the other hand, it is also determined that synkavit can directly be radioiodinated using different iodination techniques, and iodogen especially can be successfully used as an oxidative agent.
