Summary: In this study, CuPPaCC conjugate was synthesized for ROS-mediated cancer therapy. CuPPaCC continuously produced cytotoxic ROS and oxygen through a photo-chemocyclo reaction, alleviated hypoxia, and inhibited HIF-1α expression. The results showed that CuPPaCC has excellent antitumor activity.

Summary: Ruthenium(II)-based coordination complexes have great potential as photosensitizers for photodynamic therapy. The modular architectures of these complexes allow for tuning of various properties such as cellular uptake, subcellular targeting, solubility, and light absorption. Many studies focus on systematic variation of ligands to investigate their impact on photophysical and photobiological performance. However, comparisons between Ru(II)-based PSs and other generations of PSs are scarce. Nonetheless, quantitative models based on PDT dose metrics are available for qualitative comparisons. This review summarizes the relevant studies on Ru(II)-containing PSs and their potential efficacy.

Summary: A highly efficient metabolizable type-II photosensitizer with aggregation-induced emission characteristics was developed in this study, demonstrating good anti-tumor PDT efficiency in mouse models. Importantly, the photosensitizer can be gradually oxidized by endogenous hypochlorite after PDT and subsequently excreted through urine within 24 hours of administration.

Summary: One of the most challenging problems in treating glioblastoma (GBM) is its highly infiltrative nature. Researchers have found that using tetramethylrhodamine methyl ester (TMRM) as a photosensitizer in combination with photodynamic therapy (PDT) can target GBM cells, inducing mitochondrial damage and cell death, making it a potential direction for clinical translation.

Summary: Globally, cancer is a major cause of death, characterized by uncontrolled proliferation of tumor cells. Risk factors include exposure to carcinogens, conventional therapies, and conventional photosensitizers. Green metallic nanoparticles offer advantages over conventional therapies, and can be functionalized with different targeting moieties. This review discusses the synthesis and therapeutic potential of green synthesized metallic nanoparticles for enhanced cancer photodynamic therapy (PDT), and explores the future perspectives of nanotechnology in cancer research.

Summary: Photodynamic Therapy (PDT) is a well-known alternative cancer treatment that relies on light activation of a photosensitizer in the presence of oxygen to induce cytotoxic effects in cancer cells. Proper light delivery and the selection of an appropriate photosensitizer are crucial for the effectiveness of PDT in treating cancer.

Summary: The authors have developed a new family of photosensitizers that target pathogenic cells and retain metabolite function, enabling precise cell ablation through photodynamic therapy. By mimicking metabolic indicators of disease onset and progression, these photoactivatable probes can selectively kill pathogenic cells with high precision, offering a safer therapeutic approach that reduces potential side effects.
