Abstract
Time- and space-resolved drug delivery is highly demanded for cancer treatment, which, however, can barely be achieved with a traditional prodrug strategy. In recent years, the prodrug strategy based on a bioorthogonal bond cleavage chemistry has emerged with the advantages of high temporospatial resolution over drug activation and homogeneous activation irrespective of individual heterogeneity. In the past five years, tremendous progress has been witnessed in this field with one such bioorthogonal prodrug entering Phase II clinical trials. This Perspective aims to highlight these new advances (2019-2023) and critically discuss their pros and cons. In addition, the remaining challenges and potential strategic directions for future progress will also be included.

Abstract
Carbon monoxide has shown promise as a therapeutic agent against cancers. Reactive oxygen species (ROS)-activated CO prodrugs are highly demanded for targeted cancer treatment but remain sporadic. In addition, little attention is on how the release rate affects CO's biological effects. Herein, we describe a new type of ROS-activated metal-free CO prodrug, which releases CO with tunable release rates in response to multiple ROS and exhibits very pronounced tumor suppression effects in a mouse 4t1 breast tumor model. Importantly, for the first time, we observe both in vitro and in vivo that CO release rate has a direct impact on its antiproliferative potency and a correlation between release rate and antiproliferative activity is observed. In aggregates, our results not only deliver ROS-sensitive CO prodrugs for cancer treatment but also represent a promising starting point for further in-depth studies of how CO release kinetics affect anticancer activity.

Abstract
Staphylococcus aureus (S. aureus) infection is a major infectious skin disease that is highly resistant to conventional antibiotic treatment and host immune defense, leading to recurrence and exacerbation of bacterial infection. Herein, we developed a photoresponsive carbon monoxide (CO)-releasing nanocomposite by integrating anion-π+ type-I photosensitizer (OMeTBP) and organometallic complex (FeCO) for the treatment of planktonic S. aureus and biofilm-associated infections. After optimizing the molar ratio of FeCO and OMeTBP, the prepared nanoparticles, OMeTBP@FeCONPs, not only ensured sufficient loading of CO donors and efficient CO generation but also showed negligible free ROS leakage under light irradiation, which helped to avoid tissue damage caused by excessive ROS. Both in vitro and in vivo results demonstrated that OMeTBP@FeCONPs could effectively inhibit S. aureus methicillin-resistant S. aureus (MRSA), and bacterial biofilm. Our design has the potential to overcome the resistance of conventional antibiotic treatment and provide a more effective option for bacterial infections.
