autophagic process, has emerged as a pathway involved in degrading dysfunctional mitochondria. Herein, new platinum(II)-based chemotherapeutics with mitophagy-targeting properties are proposed. Four novel binuclear anticancer Pt(II) complexes with 4′-substituted-2,2′:6′,2′′-terpyridine derivatives (tpy1–tpy4), i.e., [Pt2(tpy1)(DMSO)2Cl4]·CH3OH (tpy1Pt), [Pt(tpy2)Cl][Pt(DMSO)Cl3]·CH3COCH3 (tpy2Pt),
线粒体自噬是一种选择性自噬过程,已成为参与降解功能失调线粒体的途径。在此,提出了具有线粒体自噬靶向特性的新型铂 ( II ) 化疗药物。四种新型双核抗癌Pt( II )与4'-取代-2,2':6',2''-三联吡啶衍生物(tpy1–tpy4)的配合物,即[Pt 2 (tpy1)(DMSO) 2 Cl 4 ] ·CH 3 OH ( tpy1Pt )、[Pt(tpy2)Cl][Pt(DMSO)Cl 3 ]·CH 3 COCH 3 ( tpy2Pt )、[Pt(tpy3)Cl][Pt(DMSO)Cl 3 ]( tpy3Pt ) ,和[Pt(tpy4)Cl]Cl·CH 3 OH ( tpy4Pt ),被设计和制备。此外,还研究了它们潜在的抗肿瘤机制。与针对卵巢 SK-OV-3 (SKO3) 癌细胞和正常 HL-7702 肝 (H702) 细胞的细胞毒性相比, Tpy1Pt–tpy4Pt对顺铂耐药 SK-OV-3/DDP
