Abstract

(Figure Presented) Circumventing cisplatin resistance: The trans-[PtCl ₂(NH₃)(pip-pip)]⁺ ion (see structure; red Pt, blue N, green Cl, gray C) is a cytotoxic compound with a cationic piperidinopiperidine ligand. The piperidine ring that is removed from the Pt^II center is fluxional and acts as a hydrogen-bond donor. The complex binds calf thymus DNA directly and rapidly (t_1/2 = 11 min) without prior hydrolysis and circumvents cisplatin resistance in ovarian cancer cells.
