The 7-(2-aminoethylamino)-5-methyl-3-cyanopyrazolo[ 1,5-a]pyrimidine (AMCPP) was synthesized and conjugated with N-mercaptoacetylglycine (MAG), N-mercaptoacetylphenylalanine (MAF), and N-mercaptoacetylvaline (MAA), respectively. These three compounds were labeled successfully with [ 99mTcN]2+ intermediate in high radiochemical purities. Biodistribution in tumor-bearing mice demonstrated that the three new complexes showed high tumor-to-muscle (T/M) ratios and rapid clearance from the blood, muscle, liver, kidney, and lung. Among them, the 99mTcN-MAG-AMCPP showed the most favorable characteristics. The tumor/blood and tumor/muscle ratios reached 1.50 and 1.15 at 30 min post-injection, 2.20 and 1.83 at 60 min post-injection. Springer Science+Business Media, LLC 2011.
