Summary: Platinum-based anticancer drugs have been widely used in clinical practice for over 40 years, with a focus on developing platinum(IV) prodrugs based on traditional platinum(II) anticancer drugs. Recent progress in the field includes synthesizing platinum(IV) prodrugs with new oxidizing reagents, understanding the hydrolysis and stability of platinum(IV) complexes, and exploring reduction processes to achieve controllable intracellular reduction of platinum(IV) prodrugs. This review aims to enhance researchers' understanding of platinum(IV) anticancer prodrugs and inspire new strategies, ideas, and applications in metal-based drugs.

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: The research explores the anticancer potential of platinum(IV) complexes and investigates the effects of non-steroidal anti-inflammatory drug (NSAID) ligands on their cytotoxicity. The synthesis and characterization of nine platinum(IV) complexes are presented, and their cytotoxic activity is evaluated against ovarian carcinoma cell lines. The most promising complex, Compound 7, induces cell cycle arrest and apoptosis or necrosis in a cell line-dependent manner, acting through a stress response pathway involving p21, CHOP, and ATF3 genes.

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: 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: Even in the era of precision medicine and immunotherapy, chemotherapy with platinum drugs is still widely used against various cancers. However, the efficacy of these drugs is limited by resistance and toxicity. In this study, we designed kinetically inert organometallic platinum anticancer agents with a novel mechanism of action. Our best candidate showed promising antitumor efficacy and could mitigate nephrotoxicity associated with cisplatin. This study demonstrates the importance of kinetic inertness in improving the therapeutic benefits of platinum-based anticancer therapy.

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: Researchers designed composite nanoparticles (NP-Pt-IDOi) to encapsulate a Pt(IV) prodrug (Pt(IV)-C12) and an IDO inhibitor (NLG919) for the treatment of osteosarcoma. These nanoparticles can dissociate inside cancer cells due to intracellular ROS, releasing Pt(IV)-C12 and NLG919. They have shown superior anti-cancer activity in vitro and in vivo, providing a new clinical paradigm for combining chemotherapy with immunotherapy for osteosarcoma.

Summary: Thionation of carbonyl groups in known dyes has proven to enhance singlet oxygen production and shift the absorption band, suggesting a potential strategy for developing heavy-atom-free photosensitizers for photodynamic therapy (PDT). In this study, the effect of sulfur and selenium substitution for oxygen in the oxo-4-dimethylamino-1,8-naphthalimide molecule was investigated. The thio- and seleno-derivatives were found to allow for multiple intersystem crossing pathways, leading to increased singlet oxygen production. Moreover, the transition from a (1)pi pi* to a (1)n pi* state in the selenium derivative was crucial for reaching clinically useful regions of the spectrum. These findings suggest that selenium-for-oxygen substitution could be a promising strategy for developing more suitable PDT agents and advancing heavy-atom-free photosensitizers.

Summary: The photophysical properties of two classes of porphyrins and metalloporphyrins linked to N-heterocyclic carbene (NHC) Au(I) complexes were investigated for their potential application in photodynamic therapy. Results showed that these compounds possess appropriate properties for generating cytotoxic singlet molecular oxygen and can be used as photosensitizers. The heavy atom effect in promoting the intersystem crossing process was found to vary depending on the identity and position of the metal center in the porphyrin core or linked to the peripheral NHC.

Summary: The effect of sulfur and selenium replacement in the DMNP molecule on its photophysical properties has been investigated using density functional theory (DFT). Computed structural parameters, excitation energies, singlet-triplet energy gaps (?ES-T), and spin-orbit coupling constants (SOC) suggest an enhanced probability of intersystem crossing (ISC) in the thio- and seleno-derivatives, leading to increased singlet oxygen quantum yields. Additionally, electron transfer mechanisms indicating dual Type I/Type II activity were found for all compounds.
