论文部分内容阅读
Two new Cu(Ⅱ) complexes of C2-symmetrical dimers of monopyrrole-polyamide 2 and dipyrrole-polyamide 6 tethered with EDTA analogue (i.e., Cu-2 and Cu-6), were found to be capable of efficiently converting pBR322 DNA into open circular and linear forms under physiological conditions, most probably via an oxidative mechanism.
