Summary: A method for the synthesis of 2-(1H-imidazol-1-yl)-4H-chromen-4-one derivatives (IMCMs) was developed through a one-pot cascade reaction, involving various reactions such as 1,2-addition, Michael reaction, ring-closing, tautomerization, ring-opening, and [3 + 2] cyclization. This strategy not only enabled the synthesis of functionalized imidazoles (IMCMs), but also the synthesis of useful enamine building blocks, making it suitable for combinatorial and parallel syntheses of IMCMs.

Summary: A new series of 4-(1H-benzo[d]imidazol-1-yl)pyrimidin-2-amine linked sulfonamide derivatives were designed and synthesized based on established V600EBRAF inhibitors. Among them, 12e, 12i, and 12l showed the strongest inhibitory activity against V600EBRAF, with 12l having the lowest IC50 of 0.49 μM. Further studies revealed that 12e exhibited significant growth inhibition against multiple cancer cell lines and warrants further investigation into its effect on cell cycle progression. Additionally, virtual docking studies provided insights into the binding modes of vemurafenib and the synthesized compounds.

Summary: Defect engineering has played a significant role in promoting the application of various technologies. However, selectively manufacturing defect sites in existing material systems remains challenging. This study demonstrates in situ site-directed tailoring of metal sites in Prussian blue analogs (PBA) by utilizing the reducibility differences of different metal atoms, resulting in naturally nonpreferred unsaturated coordination centers. The in situ capture of small reducing molecules also allows for site-directed tailoring of crystal facets during growth, leading to oriented 1D growth. The resulting PBA with nonpreferred unsaturated coordination centers exhibit excellent catalytic properties for the oxygen evolution reaction, making it suitable for various applications.
