The [H-3] and [Tc-99m] synthesis of three new compounds, N-[3-(pyridinio)propyl] cyclam (NPPC), N-[3-(triethylammonium)propyl] cyclam (NTPC) and N-[3-(triethylammonium)propyl]-15ane-N5 (NTP 15-5), potential tracers for cartilage, is reported. NPPC and NTPC were labelled with tritium on the ethyl group of cyclam with a specific radioactivity of 89 MBq/mmol. The [Tc-99m]-labelling of the three quaternary ammonium chelates was realized with a high specific activity in the range 20-25 MBq/mu mol.
