The complex was characterized elemental analysis and IR, UV-Vis, NMR and mass spectroscopes. The technetium tracer 99mTcO-complex has also been synthesized by two methods using Ligand exchange method and direct reduction method. The radiochemical purity of the complex was over 95% as measured by thin layer chromatography. In vitro studies showed that the complex possessed good stability under physiological conditions. The partition coefficient indicated that the complex hydrophilic and the electrophoresis results showed that the complex neutral. Normal biodistributions of the 99mTC complex exhibit high lung, liver and spleen uptake of 27%, I 1%, and 12%, respectively. Blood and lungs clearance was quite, while liver activity remained high for a longer period with 12% injection dose present at 1 h post-inj ection. The radioactivity from the novel technetium complex was excreted mainly through the hepatobiliary system, which passed 35% of the complex at 1 h post-injection, and partially through the kidneys.展开更多

The objective of the present study was to establish and validate a high performance liquid chromatography （HPLC） method for the determination of ethaselen in its injection formulation. Analysis was performed on an ODS column with isocratic elution at 40 ℃. Mobile phase was consisted of 0.01% phosphoric acid and methanol （60：40, v/v）. The detection wavelength was set at 320 nm and the flow rate was 1.0 mL/min. The results showed that the calibration curves of ethaselen were linear in the range of 10-50 μg/mL （r2 = 0.9999）. The limit of detection for ethaselen was 100 ng/mL. The average recovery of ethaselen was 100.14%. The labeled content of ethaselen in its injection formulation was in the range of 102%-103% of the measured content. In conclusion, this method was stable and reproducible, thus providing a useful tool for the routine analysis of this novel ethaselen injection formulation.展开更多
