Аннотация

Derivatives of 2-thiouracil are known to incorporate into the growing melanin pigment of melanomas as false melanin precursors. Animal and pilot patient studies have demonstrated, that radioiodinated 5-iodo-2-thiouracil is a promising agent for visualization of melanotic melanomas. In this study, 2-bromo-2-thiouracil was labeled using the positron-emitting isotope 76Br (T1/2 = 16.2 h), which potentially enables to use such advantages of PET as superior spatial resolution and possibility to quantify radioactivity concentration in vivo. The use of Chloramine-T as oxidant provided a labeling efficiency of about 70%.
