Two-in-one strategy to enhance the stability of TiCT in transition metal ion solutions.

Although MXenes have attracted significant attention across diverse fields, they exhibit a pronounced susceptibility to oxidation in aqueous environments, with oxidation significantly accelerated in the presence of transition metal ions (TMI) such as Fe and Cu. This limitation impedes the synthesis of transition metal compounds/MXene-based composites and their potential for functional applications. In this study, we elucidate the mechanism of accelerated oxidation of TiCT is that Fe promotes the electron loss in TiCT, thus leading to an increased production of hydroxyl radicals (OH) to oxidize TiCT.

Enterovirus-D68 (EV68) continues to present as a global health issue causing respiratory illness and outbreaks associated with long-lasting neurological disease, with no antivirals or specific treatment options. The development of antiviral therapeutics, such as small-molecule inhibitors that target conserved proteins like the enteroviral 3C protease, remains to be achieved. While various 3C inhibitors have been investigated, their design does not consider the potential emergence of drug resistance mutations.

Hepatic fibrosis (HF) is an important pathological state in the progression of chronic liver disease to end-stage liver disease and is usually triggered by alcohol, nonalcoholic fatty liver, chronic hepatitis viruses, autoimmune hepatitis (AIH), or cholestatic liver disease. Research on novel therapies has become a hot topic due to the reversibility of HF. Research into the molecular mechanisms of the pathology of HF and potential drug screening relies on reliable and rational biological models, mainly including animals and cells.

Viridin and viridiol, along with wortmannin, metabolized by filamentous fungus Trichoderma virens, are identical furanosteroids with high-potent inhibitory activity towards phosphatidylinositol 3-kinase (PI3K) that associates the growth of tumor cells. Therefore, structure-activity relationship study (SAR) of these furanosteroids contributes to the development of novel drugs. However, rational supply methods have not been established yet.
