Abstract  

One novel styrylpyridine derivatives(AV-45) coupled with 99mTc complex was synthesized. 99mTc-BAT-AV-45 was prepared by a ligand exchange reaction employing sodium glucoheptonate, and effects of the amount of ligand, stannous chloride, sodium glucoheptonate and pH value of reaction mixture on the radiolabeling yield were studied in details. Quality control was performed by thin layer chromatography and high performance liquid chromatography. Besides the stability, partition coefficient and electrophoresis of 99mTc-BAT-AV-45 were also investigated. The results showed that the average radiolabeling yield was (95 ± 1%) and 99mTc-BAT-AV-45 with suitable lipophilicity was stable and uncharged at physiological pH.
