Popis: [67Ga]-ethylenecysteamine cysteine ([67Ga]ECC) was prepared using freshly prepared [67Ga]GaCl3 and ethylenecysteamine cysteine (ECC) for 30 min at 90 °C (radiochemical purity ≈97 ± 0.88% ITLC, specific activity: 210 ± 5 GBq/mM). Stability of the complex was checked in human serum for 24 h at 37 °C. Partition co-efficient of the tracer in octanol:saline mixture was determined (log P; 0.8). The biodistribution of the radiolabeled compound in vital organs of wild-type rats were compared with that of free Ga3+ cation up to 48 h. Initial biodistribution results showed significant kidney excretion of the tracer comparable to that of homologous 99mTc compound.
