Graphical Abstract

Umgehen der Cisplatinresistenz: Das trans-[PtCl2(NH3)(pip-pip)]+-Ion (siehe Struktur; rot Pt, blau N, grün Cl, grau C) ist eine cytotoxische Verbindung mit einem kationischen Piperidinopiperidin-Liganden. Der vom PtII-Zentrum entfernte Piperidinring ist fluktuierend und fungiert als Wasserstoffbrücken-Donor. Der Komplex bindet ohne vorherige Hydrolyse Kalbsthymus-DNA direkt und schnell (t1/2=11 min) und umgeht die Cisplatinresistenz von Eierstockkrebszellen.
