central tricyclic core, leading to several subseries of compounds, including those unexpectedly cyclized complex ones. Compound 25 bearing an N-glycylglycinoyl side chain was identified as the most potent one with cellular IC50 values of 1.38 and 11.4 μM for h- and m-cGAS, respectively. Mechanistic studies confirmed its direct targeting of cGAS. Further, compound 25 showed superior in vivo anti-inflammatory

An onium salt having formula (1) serving as an acid diffusion inhibitor and a chemically amplified resist composition comprising the acid diffusion inhibitor are provided. When processed by lithography, the resist composition exhibits a high sensitivity, and excellent lithography performance factors such as CDU and LWR.
A facile silver-catalyzed oxidative decarboxylation of arylthiodifluoroacetic acids or aryloxydifluoroacetic acids with coumarins/quinoxalin-2(1H)-ones was developed. This transformation provided a series of C-3 aryloxydifluoromethylated or arylthiodifluoromethylated coumarins/quinoxalin-2(1H)-ones containing various functional groups in moderate to good yields, featuring good functional group tolerance
开发了一种简便的银催化芳硫基二氟乙酸或芳氧基二氟乙酸与香豆素/喹喔啉-2(1 H )-酮的氧化脱羧反应。该转化提供了一系列C-3芳氧基二氟甲基化或芳硫基二氟甲基化香豆素/quinoxalin-2(1 H )-ones,其含有各种官能团,产率中等至良好,具有良好的官能团耐受性、易于获得的起始材料和操作简单性。

backbone, and incorporation of unnatural amino acids. One approach previously established, is the use of halogenated aromatic amino acids. In principle, they are thereby enabled to form halogen bonds (XB). In this study, we focus on the -R-CF2X moiety (R = O, NHCO; X = Cl, Br) as an uncommon halogenbonddonor. These groups enable more spatial variability in protein–protein interactions. The chosen approach
