Enhanced cancer cell killing of a Pt(iv) prodrug promoted by outer-sphere coordination with polyethyleneimines†
Abstract
The cisplatin prodrug c,c,t-[Pt(NH3)2Cl2(O2CCH2CH2CO2)2]2− (1) forms outer-sphere coordination interactions with non-toxic low MW PEI, which results in enhanced cancer cell killing, also achieved using PEI-coated AuNPs.
