Chemical and biological properties of a cationic Tc-tetraamine complex

Int J Appl Radiat Isot. 1985 Apr;36(4):315-7. doi: 10.1016/0020-708x(85)90093-6.

Abstract

The complex of 99Tc with the ligand 1,4,8,11-tetraazaundecane (2,3,2-tet) was prepared and was compared with the similar 99Tc complexes with ethylenediamine and 1,4,8,11-tetraazacyclotetradecane. The results are all consistent with the formula [TcO2(2,3,2-tet)]+. The biological behavior was tested with 99mTc in Wistar rats. A fast clearance via the kidneys was found, and no accumulation in any other organ was observed.
