Summary: Platinum-based anticancer drugs have led to the development of ruthenium and rhodium compounds with potential anticancer activity, with rhodium complexes showing promising in vitro potency as alternatives to conventional platinum and ruthenium-based metallodrugs. The review focuses on half-sandwich Rh(III) complexes, which exhibit higher in vitro potency and different mechanisms of action compared to cisplatin or clinically studied Ru drug candidates. Additionally, some of the discussed Rh(III) arenyl complexes have shown anticancer activity in vivo, highlighting the potential of organorhodium compounds in anticancer therapies.

Summary: In this study, four half-sandwich iridium(III) (IrIII) and ruthenium(II) (RuII) diphenylphosphino ferro-cene (dppf) complexes with potential applications in anticancer were prepared. These complexes exhibited favorable anti-proliferation activity against A549 cell lines and inhibited cell migration effectively compared to cisplatin. They were taken up by cells through an energy dependence mechanism, accumulated in mitochondria, disrupted mitochondrial membrane potential, induced reactive oxygen species production, disrupted cell cycle, and ultimately led to apoptosis. Western blot assay confirmed that these complexes induced apoptosis through a mitochondrial pathway. Overall, half-sandwich IrIII and RuII dppf complexes show promise as a new multifunctional therapeutic platform for mitochondrial targeted imaging and anticancer drugs.

Summary: In order to optimize dosing, the researchers investigated the pharmacokinetics and minimum inhibitory concentration (MIC) distribution of moxifloxacin in participants with multidrug-resistant tuberculosis (MDR-TB). Using nonlinear mixed-effects modeling and simulations, they analyzed plasma drug concentrations and clinical data to evaluate different dosing scenarios. The results showed that participants treated with efavirenz had increased clearance of moxifloxacin, resulting in reduced exposure. Simulations suggested that higher doses of moxifloxacin were needed to achieve target levels, particularly in heavier participants. The high-dose WHO regimen yielded more balanced exposures across different weight ranges. The safety of higher doses of moxifloxacin should be confirmed in clinical settings.

Summary: The success of small metal-containing molecules as pharmaceutical agents has led to investigations into the pharmacological activity of supramolecular coordination complexes (SCCs), which have shown promising anticancer activity. The present study evaluated the anticancer activity of quinoline-containing binuclear complexes and metallarectangles in breast cancer cell lines. The results demonstrated that some of these complexes exhibited superior or comparable activity to the clinical chemotherapeutic drugs cisplatin in different breast cancer cell lines. Additionally, the compounds showed increased selectivity towards breast cancer cells over non-tumorigenic cells and displayed favorable binding to DNA and albumin.

Summary: The synthesis of gold nanoparticles (AuNPs) using phytochemicals is of great interest in biomedical applications. In this study, honeybush water extracts were used to synthesis honeybush gold nanoparticles (HB-AuNPs). The HB-AuNPs showed selective cytotoxicity against cancer cells and enhanced the anti-cancer effects of doxorubicin. Furthermore, HB-AuNPs induced cell death through apoptosis. Further studies are needed to understand the mechanisms and phytochemicals involved in the synthesis and activity of HB-AuNPs.

The method was further clinically validated through a pharmacokinetic pilot study, showing that DBS and plasma concentrations can be used interchangeably. The results suggest that the assay is suitable for assessing adherence to carvedilol and perindoprilat, as well as enalaprilat.

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.
