abstract = {5-Iodotubercidin is a prototype adenosine kinase (AK)
inhibitor with potent anti-seizure activity in rodent
epilepsy models. Using the chloramine-T method for
radioiodination of tubercidin with 131I, we prepared
no-carrier-added 5-[131I]iodotubercidin (5-[131I]IT) in a
radiochemical yield of $61 ± 13\%$ and with a
radiochemical purity of $> 99\%$ (molar
activity = 10–40 GBq/µmol). In vitro competition and
saturation experiments demonstrated specific binding of
5-[131I]IT in rodent brain slices (KD ~ 31 nM), but ex
vivo autoradiography revealed its accumulation in cerebral
vessels. We conclude that 5-[131I]IT could be a useful tool
for the detection and quantification of AK in in vitro
studies.},
