Lewis basic salts promote benzyltrimethylsilane coupling with (hetero)aryl nitriles, sulfones, and chlorides as a new route to 1,1-diarylalkanes. This method combines the substrate modularity and selectivity characteristic of cross-coupling with the practicality of a base-promoted protocol. In addition, a Lewis base strategy enables a complementary scope to existing methods, employs stable and easily prepared organosilanes, and achieves selective arylation in the presence of acidic functional groups. The utility of this method is demonstrated by the synthesis of pharmaceutical analogues and its use in multicomponent reactions.

Background: The effects of ionizing radiation (IR) involve a highly orchestrated series of events in cells, including DNA damage and repair, cell death, and changes in the level of proliferation associated with the stage of the cell cycle. A large number of existing studies in literature have examined the activity of genes and their regulators in mammalian cells in response to high doses of ionizing radiation. Although there are many studies, the research in effect of low doses of ionizing radiation remains limited.

Purpose Of Review: For many years, inflammation has been a major concept in basic research on atherosclerosis and in the development of potential diagnostic tools and treatments. The purpose of this review is to assess the performance of this concept with an emphasis on recent clinical trials. In addition, contemporary literature may help identify new therapeutic targets, particularly in the context of the treatment of early, rather than end-stage, arterial disease.

Poly(ethylene oxide) (PEO) has been widely studied as an electrolyte owing to its excellent lithium compatibility and good film-forming properties. However, its electrochemical performance at room temperature remains a significant challenge due to its low ionic conductivity, narrow electrochemical window, and continuous decomposition. Herein, we prepare a multifunctional polar polymer to optimize PEO's electrochemical properties and cycling stability.

Background: Natural glucocorticoids (GCs) have been widely used to treat acute multiple sclerosis (MS) attacks. However, they also cause significant side effects related to immunosuppression. Our previous study found that C16 peptide combined with angiopoietin-1 (Ang-1) inhibited inflammatory cell infiltration and protected blood vessels in animal models of inflammatory neurodegenerative diseases.

In this study, a highly porous muffin polyhedral barium (Ba) ̵ organic framework (BaTATB; HTATB = 4,4',4″--triazine-2,4,6-triyl-tribenzoic acid) was synthesized solvothermally. The three-dimensional honeycomb pore architectures were densely populated with Lewis acidic Ba(II) metal sites and basic nitrogen-rich triazines.
