Summary: A series of Pt(IV) prodrugs containing a microtubule inhibitor paclitaxel were synthesized and evaluated for their antitumor activity. One of the prodrugs, named Ptxplatin, effectively entered cancer cells and induced DNA damage, cell cycle arrest, and inhibition of cell migration. Furthermore, Ptxplatin caused mitochondrial dysfunction and triggered endoplasmic reticulum stress, ultimately leading to cancer cell death.

Summary: In this study, a novel Pt(IV) prodrug of oxaliplatin (OXA) was synthesized and prepared as self-assembled micellar nanoparticles (PEG-OXA NPs). In vitro experiments showed that PEG-OXA NPs rapidly released biologically active OXA within 5 minutes in tumor cells while remaining extremely stable in whole blood or plasma. Pharmacokinetic results demonstrated that PEG-OXA NPs had a longer drug circulation time and improved antitumor efficacy compared to free OXA solution. These findings suggest that PEG-OXA NPs have the potential to be a desirable self-delivery platform for platinum drugs in anticancer therapeutics.

Summary: The platinum (IV) prodrug, which binds to albumin, enhances the efficacy of oxaliplatin therapy by facilitating tumor-specific release and accumulation, resulting in prolonged terminal excretion half-life and increased effective platinum dose. This innovative approach shows significant anticancer activity against colon tumors in vivo and should be further developed for clinical trials.

Summary: Platinum-based drugs have been successful in treating solid tumors, but toxicity and resistance limit their outcomes. Natural products, such as 10-HDA found in royal jelly, are being explored as safe and easily available anti-cancer drugs. In this study, the researchers aimed to combine the functionality of 10-HDA with platinum to develop new compounds with potential anti-cancer activity. The synthesized compounds were characterized and tested for their cytotoxicity against human tumor cell lines. The results showed that some of the new compounds exhibited promising activity against specific tumor cell lines.

Summary: The interaction between a photoactivatable Pt(iv) prodrug and human telomeric DNA was studied. Two major mono-platinated DNA adducts were detected, with trans-[Pt-II(N-3)(py)(2)](+) and trans-[Pt-II(py)(2)](2+) as the bound Pt moieties. The platination sites were found to be G(6) and A(3) in one adduct, and a potential intrastrand crosslink was speculated after G(4) and G(6) in the other adduct. Minor platinated adducts and oxidized DNA adducts were also observed. These results provide valuable chemical information about the photoreaction between photoactivatable Pt(iv) anticancer prodrugs and human telomeric DNA.

Summary: Encapsulating cisplatin in calcium phosphate nanoparticles is challenging due to its low solubility and weak binding affinity. This study presents a unique strategy using a polymer bearing numerous carboxyl side groups and incorporating redox-sensitive cisplatin prodrugs for encapsulation in CPNPs. The encapsulated CPNPs showed enhanced stability and efficacy against cancerous cells compared to free cisplatin and the prodrug alone.

Summary: Manipulating Fenton chemistry in tumor microenvironment (TME) for the generation of reactive oxygen species is an effective strategy for chemodynamic therapy. Here, a nanozyme MOF-Pt(IV)@GOx was developed by covalently grafting a prodrug of cisplatin (Pt(IV) prodrug) onto a ferric metal-organic framework (MOF) and loading it with a biocatalyst glucose oxidase (GOx). The system achieved synergistic trimodal therapy consisting of ferroptosis, starvation therapy, and chemotherapy, by enhancing GOx loading and chemotherapy, reducing Fe(III) to Fe(II) for Fenton reaction, converting Pt(IV) prodrug to cisplatin, and promoting intracellular acidity and H2O2 supply in TME.

Summary: Platinum (IV) anticancer agents show potential to overcome limitations of commonly used Pt (II) chemotherapeutics and an improved understanding of their intracellular reduction is needed. Two fluorescence responsive oxaliplatin (IV) complexes, OxaliRes and OxaliNap, were synthesized and showed increased fluorescence emission intensity upon reduction by sodium ascorbate (NaAsc). Treatment with NaAsc increased fluorescence intensity in a dose-dependent manner in colorectal cancer cells. Hypoxia-induced reduction of OxPt (IV) complexes with <0.1% O-2 resulted in the greatest fluorescence signal and showed significant differences in toxicity compared to normoxia (21% O-2).

Summary: Novel ER-targeted prodrugs have been developed with activation only in cancer cells, demonstrating anticancer efficacy and cancer cell specificity. These prodrugs induce ER stress, attenuate mitochondrial membrane potential, and generate mitochondrial ROS leading to cell death via necrosis. Activation of the new prodrugs has also been demonstrated in the Nemeth-Kellner lymphoma murine model.

Summary: Elevated levels of reactive oxygen species (ROS) and deficient mitochondria are weak points of cancer cells. Designing highly potent anticancer drugs that target both ROS and mitochondria is a valid therapeutic strategy. However, limiting the drug effects to cancer cells without affecting normal ones remains a challenge. In this study, we developed novel aminoferrocene derivatives that are chemically stable in the presence of ROS, generate mitochondrial ROS in cancer cells but not normal cells, and exhibit anticancer effects in vivo.

Summary: In this study, symmetrical cationic trimethine cyanine dyes with ss-substituents were proposed as probes for detecting and visualizing live and fixed cells by fluorescence microscopy. The dyes showed increased emission intensity in the presence of nucleic acids and were found to bind to nucleic acids through various interaction mechanisms. The dyes were able to stain cell components, including nuclei and certain organelle structures, with different levels of specificity. The benzoxazole dye T-5 showed selective staining of structures associated with mitochondria or lysosomes and could be used as an alternative to commercial dyes for mitochondria staining.

Summary: A new aryl selenonium polyoxometalate hybrid was developed and compared with an aryl sulfonium polyoxometalate hybrid in terms of their photocatalytic properties. It was found that the aryl selenonium hybrid exhibited better catalytic performance, which could be attributed to the larger atomic radii of selenium stabilizing the photogenerated electron-hole pair more efficiently. Additionally, the generation of elemental selenium through cleavage of C-Se bonds during catalysis was observed.
