Cu(II) complexes with ATCUN peptide ligands have been investigated for their ROS (reactive oxygen species) generation and oxidative DNA degradation abilities. The biological activity of most ATCUN complexes such as Cu-GGH (Gly-Gly-His) is, however, low. Tuning the redox chemistry by incorporation of N-heteroaromatics reinstates ROS production which leads to efficient DNA cleavage.
已经研究了具有 ATCUN 肽配体的Cu( II ) 复合物的 ROS(活性氧)生成和氧化 DNA 降解能力。然而,大多数 ATCUN 复合物如 Cu-GGH (Gly-Gly-His) 的生物活性都很低。通过掺入 N-杂芳烃来调整氧化还原化学可恢复 ROS 的产生,从而实现有效的 DNA 切割。
