摘要: Abstract Two EDTA analogue-tethered C 2 -symmetrical dimeric monopyrrole-polyamide 5 and dipyrrole-polyamide 6 , their corresponding Ce(IV) complexes Ce- were synthesized fully characterized. Agarose gel electrophoresis studies on pBR322 DNA cleavage indicate that exhibited potent DNA-cleaving activities under physiological conditions. The maximal first-order rate constants ( k max 's) (0.42 ± 0.02) h −1 for (0.52 ± 0.02) h respectively, suggesting both catalyzed the of supercoiled by up to approximately 10 8 -fold. Complex ca 10-fold higher overall catalytic activity / K M ) than which may be ascribed its DNA-binding affinity. Inhibition experiments a model study convincingly suggest functioned as hydrolytic DNA-cleavers. In addition, found display moderate inhibitory toward A549 HepG-2 cells.
