All possible configurations of two different groups on the four nitrogen atoms of cyclen were achieved using four differently protected cyclen intermediates including the novel mono-protected cyclen compound, mono-N-Cbz-cyclen.

number of acetate groups increased, the lipophilicity was decreased. The biodistribution of Cu-cyclen complexes was found to be influenced mostly by the overall charge of the complexes rather than their lipophilicity. Positively charged (+2) complexes showed high blood retention at early time points with sluggish clearance from liver by 24 h. The attachment of even one acetate group onto cyclen accelerated
