From a chemistry-based perspective, this review discusses the most recent advances in the field of substrate-based probes for the detection and analysis of proteolytic activity both in vitro and in vivo.
A ruthenium‐based mitochondrial‐targeting photosensitiser that undergoes efficient cell uptake, enables the rapid catalytic conversion of PtIV prodrugs into their active PtII counterparts, and drives the generation of singlet oxygen was designed. This dual mode of action drives two orthogonal cancer‐cell killing mechanisms with temporal and spatial control. The designed photosensitiser was shown to elicit cell death of a panel of cancer cell lines including those showing oxaliplatin‐resistance.
The term electroceutical has been used to describe implanted devices that deliver electrical stimuli to modify biological function. Herein, we describe a new concept in electroceuticals, demonstrating for the first time the electrochemical activation of metal-based prodrugs. This is illustrated by the controlled activation of Pt(iv) prodrugs into their active Pt(ii) forms within a cellular context allowing selectivity and control of where, when and how much active drug is generated.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
