intrinsic pathway of apoptosis. Moreover, compound 4 triggers the activity of caspase-3/7, which eventually induces the apoptotic cellular death of A549 cells. Thus, increasing the overall lipophilicity of the Ru compounds by introducing π-extended moieties in the anionic N∧O– ligand is a successful strategy for realizing a new family of pro-apoptotic compounds with a [RuIIN5O]+ coordination environment
Ru(II)-聚吡啶配合物表现出抗肿瘤特性,可以通过调整配体环境来系统地定制。在这项工作中,探讨了将 π 扩展部分结合到基于 N ∧ O的阴离子螯合配体中对 Ru 化合物的细胞毒性的影响。四种新的 Ru(II) 配合物,[Ru(bpy) 2 (dphol)][PF 6 ] ( 1 ; bpy = 2,2'-bipyridine, dphol = dibenzo[ a , c ]phenazin-10-olate),[ Ru(phen) 2 (dphol)][PF 6 ] ( 2 ; phen = 1,10-phenanthroline), [Ru(bpy) 2 (hbtz)][PF 6 ] ( 3; hbtz = 2-(benzo[ d ]thiazol-2-yl)phenolate) 和 [Ru(phen) 2 (hbtz)][PF 6 ] ( 4 ) 被合成并彻底表征。在人肺腺癌细胞 (A549)
