Summary: This study has successfully developed a series of curcumin derivatives through modifications. The results showed that one derivative with PEG chains and a BF2 moiety exhibited higher cytotoxicity against bladder cancer cells and stronger anticancer effects under hypoxic conditions. However, PEGylation did not improve cellular uptake, and the lack of serum proteins limited intracellular uptake. The regulation of cell cycle and stress-related proteins may be involved in the anticancer mechanism. In conclusion, PEGylated curcumin derivatives are more effective anti-bladder cancer drugs than the parent compound, and derivative 5 deserves further investigation to elucidate its anticancer mechanism under hypoxic conditions.

Summary: Ferrocene is widely used in modern organometallic chemistry for its versatility in various applications such as material sciences, catalysis, medicinal chemistry, and diagnostics. In this study, a novel maleonitrile derivative was obtained by combining (6-bromo-1-oxohexyl)ferrocene with dimercaptomaleonitrile sodium salt. The maleonitrile derivative was then subjected to an autocyclotetramerization reaction to yield an octaferrocenyl-substituted magnesium(II) sulfanyl porphyrazine. Both compounds were comprehensively characterized using various physicochemical techniques. The sulfanyl porphyrazine derivative was further studied to determine its photophysical properties and singlet oxygen generation quantum yields in different organic solvents. The electrochemical properties of the synthesized compounds were also investigated using cyclic voltammetry, showing that the presence of electron-withdrawing oxohexyl groups attached to ferrocene resulted in significantly positive oxidation potentials of the ferrocene-based redox process, up to 0.34 V vs. Fc(+)/Fc.

Summary: Cannabis-derived therapies, particularly cannabidiol (CBD), have shown potential in the treatment of metabolic syndrome components such as obesity, impaired glucose and lipid metabolism, high blood pressure, and NAFLD. CBD has been found to have positive effects on glucose homeostasis, lipid disorders, and hypertension, but more research is needed. Limited data on CBD and NAFLD in human studies make it unclear whether CBD is beneficial for this condition.
