Pyrrolidine-Containing Polypyridines: New Ligands for Improved Visible Light Absorption by Ruthenium Complexes
摘要:
A range of new electron-releasing pyrrolidine-containing bipyridines and terpyridines has been prepared via selective metalation-cross-coupling sequences. The obtained ligands have been involved in microwave-assisted ruthenium complexation leading to homoleptic complexes in high yield. The electron-donor effect of the pyrrolidine nucleus led to a notable improvement of visible light absorption and strong changes in the electrochemical behavior, opening new opportunities for the design of photovoltaic devices.

Abstract A set of homoleptic rutheniumpolypyridine (bipyridine and terpyridine) complexes flanked with several electron-donating pyrrolidine moieties has been characterized and the anticancer activity was evaluated toward human lung adenocarcinoma epithelial (A549) and murine colon carcinoma (CT26). Good antiproliferative effects were observed with an IC 50 ranging from ca. 4 to 21 μM against both
摘要表征了一组均化的钌多吡啶(联吡啶和三联吡啶)配合物,其侧翼带有多个供电子吡咯烷部分,并评估了其对人肺腺癌上皮细胞(A549)和鼠结肠癌(CT26)的抗癌活性。用约50的IC 50观察到良好的抗增殖作用。两种细胞系的抗氧化能力均为4至21μM。发现在细胞毒性,亲脂性和Ru II / Ru III氧化电位之间存在依赖性。所有研究的化合物与白蛋白的相互作用都很好,而与DNA的相互作用很小。生物学研究表明,钌络合物可诱导ROS过度生成,这可能是诱导细胞死亡的一种方法,但不是唯一的方法。
