In this Letter, a series of macrocyclic polyamine [12]aneN(3)-dipeptide conjugates as a new type of metal-free nucleases were synthesized and fully characterized with H-1 NMR, C-13 NMR, IR, and HR-MS. Results indicate that these conjugates can bind to calf thymus DNA mainly through electrostatic interaction and can cleave the plasmid DNA at 200 mu M ( pH 7.2, 37 degrees C), with an acceleration of 10(6)-fold via hydrolytic pathway.
