synthetic analogs of the natural product prodigiosin, exhibit self-activated DNA cleavage in the presence of Cu(II). In unprecedented Cu(II)-dependent cytotoxicity studies, we investigated the role of different alkyl chains at the C ring. Cytotoxicity was selective towards cancer cells and could be increased by irradiation. Some prodigiosenes also showed high antibacterial activity.
为了纪念克劳斯·哈夫纳教授。Prodigiosenes是
天然产物 prodigiosin 的合成类似物,在 Cu(II) 存在下表现出自激活的 DNA 切割。在前所未有的 Cu(II) 依赖性细胞毒性研究中,我们研究了不同烷基链在C环上的作用。细胞毒性对癌细胞具有选择性,并且可以通过照射增加。一些 prodigiosenes 也显示出高抗菌活性。
