Two novel ruthenium polypyridyl complexes, Ru[(bpy)2(pedppz)]2+ (1) and Ru[(bpy)2(pemitatp)]2+ (2) (bpy = 2′2-bipyridine, pdeppz = 10-(2-(piperidin-1-yl)ethoxy)dipyrido[3,2-a:2′,3′-c]phenazine, pemitatp = 5-methoxy-1-(2-(piperidin-1-yl)ethyl)-isatino[1,2-b]-1,4,8,9-tetraazatriphenylene), bearing large planar π-delocalized aromatic systems with flexible chains have been synthesised and characterised. As expected, these complexes show inhibition towards telomerase by inducing and stabilising the G-quadruplex structure.
两种新型钌聚吡啶配合物,Ru[(bpy)2(pedppz)]2+ (1) 和 Ru[(bpy)2(pemitatp)]2+ (2) (bpy = 2′2-联吡啶,pdeppz = 10- (2-(哌啶-1-基)乙氧基)二吡啶并[3,2-a:2′,3′-c]吩嗪,pemitatp = 5-甲氧基-1-(2-(哌啶-1-基)乙基) -isatino[1,2-b]-1,4,8,9-四氮杂苯并菲),具有柔性链的大平面π离域芳香系统已被合成和表征。正如预期的那样,这些复合物通过诱导和稳定 G-四链体结构来抑制端粒酶。
