Photoactivatable RuII Complex Bearing 2,9‐Diphenyl‐1,10‐phenanthroline: Unusual Photochemistry and Significant Potency on Cisplatin‐Resistant Cell Lines
منشور في 2018"…Upon excitation with visible light, complex 2 proved to be photostable while complex 1 underwent a quantitative dissociation of the bipy ligand and formation of a RuII polypyridyl aqua complex in water. Complex 1 demonstrated only marginal activity in the dark; its cytotoxicity increased significantly upon photoactivation with a high phototoxicity index (PI = [IC50 dark]/[IC50 light]) ranging from 39.2‐fold in A549 to over 100‐fold in MDA‐MB‐231. …"
