Summary: Pt(IV) complexes formed by linking pyrene butyric acid with cisplatin exhibit high anticancer potency against leukemia cells and multidrug-resistant derivatives, while showing low toxicity to healthy cells. The larger bis-pyrene complex is found to potentially be trapped in the cytoskeleton, limiting its cytotoxicity to adherent cells.

Summary: This review summarizes the research on the development of Pt(IV) prodrugs with NSAIDs as axial ligands, their cytotoxic action and anti-inflammatory activity mechanism studies, structure-activity ratio, and therapeutic efficacy. The chemo-anti-inflammatory strategy aims to efficiently deliver cytotoxic metabolites and NSAIDs intracellularly in tumor cells to reduce side effects and increase therapeutic efficacy. Studies have shown high therapeutic efficacy both in vitro and in vivo.

Summary: Four platinum(IV) prodrugs incorporating a biotin moiety showed exceptional cytotoxicity against cancer cell lines. One of the prodrugs exhibited the lowest cytotoxicity in prostate cancer cells, while another prodrug showed higher activity in colon cancer cells. Some prodrugs also demonstrated selectivity towards breast cancer cells compared to healthy cells, which was not observed with their platinum(II) precursors.

Summary: Pt(IV) prodrugs with a light-controlled mode of activation show high antiproliferative activity when irradiated, but are non-toxic in the absence of light. This review discusses recent advances in photoabsorber-mediated photocontrollable activation of Pt(IV) prodrugs, focusing on the photocatalytic strategy based on flavin derivatives and the conjugation of photoactive molecules with Pt(II) drugs.

Summary: We conducted the first comprehensive investigation on the impact of head group modifications on the anticancer activities of fatty-acid-like Pt(IV) prodrugs (FALPs). We created a small library of FALPs with diverse head group modifications and found that hydrophilic modifications enhanced the potency of these metallodrugs, while hydrophobic modifications decreased their cytotoxicity.

Summary: Pt-IV prodrugs can overcome resistance and side effects of conventional Pt-II anticancer therapies by efficiently promoting the two electrons reduction of Pt-IV to Pt-II. The activation of Pt-FBA is highly dependent upon the type of cancer cells, and FBA can shuttle out of the cell after Pt-FBA is reduced intracellularly. The F-19 NMR approach has the advantage of avoiding the interference of all background signals when investigating the activation of Pt-IV prodrugs.

Summary: This study reports the synthesis of Pt-IV complexes bearing axial pyridines through ligand exchange reactions. It was discovered that these axial pyridines can be quickly released after reduction, indicating their potential as axial leaving groups. Two multitargeted Pt-IV prodrugs containing bioactive pyridinyl ligands, a PARP inhibitor and an EGFR tyrosine kinase inhibitor, were successfully obtained using this method. These conjugates show great potential for overcoming drug resistance, with the latter inhibiting the growth of Pt-resistant tumor in vivo. This research expands the synthetic methods for Pt-IV prodrugs and increases the range of bioactive axial ligands that can be conjugated to a Pt-IV center.

Summary: Gold(II) complexes have been less utilized in catalysis compared to their gold(I) and gold(III) counterparts. However, gold(II) complexes offer potential in homo-coupling and cross-coupling reactions, as they are more easily accessible through simplified oxidation and reduction processes. Gold(II) exhibits characteristics of both soft acid gold(I) and hard acid gold(III). This review explores the unique reactivity and potential applications of gold(II) species, highlighting their significance in catalytic transformations.

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.
