Abstract:
A multifunctional hybrid constructed for controlling the delivery and activation of Pt anticancer agents in vitro is described herein. We employed consensus tetratricopeptide repeat protein (CTPR) for the covalent co-anchoring of riboflavin (photocatalyst) and a Pt(IV) prodrug complex. The Pt-loaded flavoprotein induced a 40% reduction in PANC-1 cell viability as a result of the photocatalytic formation of cisplatin.
