Popis: In the present study, N-acetyl neuraminic acid (Neu5Ac) was labeled with 99mTc and its bioevaluation was performed. Radiolabeling of Neu5Ac was obtained with a maximum labeling yield of 93.6% and was confirmed by instant thin layer chromatography, mass spectra (ESI-MS) and high performance liquid chromatography. The resulting radiocomplex showed hydrophilic properties and stability up to 8 h at room temperature in rat serum and saline. Biodistribution and scintigraphic studies exhibited accumulation of activity in the colon of tumor bearing rats. In conclusion, [99mTc]Tc-N-acetyl neuraminic acid exhibits selectivity for neoplastic colon tissue.
