Inhibiting NLRP3 inflammasome activation is a prospective therapeutic strategy for uncontrolled inflammatory diseases. It is the first time that dronedarone, a multiply ion channel blocker, was identified as a NLRP3-inflammasome inhibitor with an IC50 value of 6.84 μM against IL-1β release. A series of novel 5-amide benzofuran derivatives were designed and synthesized as NLRP3-inflammasome inhibitors. Compound 8c showed slightly increased activity (IC50 = 3.85 μM) against IL-1β release. Notably, treatment with 8c could significantly inhibit NLRP3-mediated IL-1β release and ameliorate peritoneal inflammation in a mouse model of sepsis. Collectively, 8c is a promising lead compound for further chemical development as a NLRP3 inhibitor with anti-inflammation effects.

The invention relates to a preparation method of a key intermediate of drug dronedarone for treating atrial fibrillation, and specifically relates to the 2-butyl-3-(4-hydroxybenzoyl)-5-nitrobenzofuran. According to the method provided by the invention, a series of reactions are performed by using inexpensive p-nitrophenol as a starting material to prepare the 2-butyl-3-(4-hydroxybenzoyl)-5-nitrobenzofuran, the process is smooth, the costs are lower, the yield is higher, the controllability is stronger, and the method is suitable for industrial production.

A practical synthesis of (2-butyl-5-nitrobenzofuran-3-yl)(4-hydroxyphenyl) methanone, a key intermediate in the preparation of anti arrhythmic drug, is described. The commercially available 4-nitrophenol (3) is converted in five steps to 2-butyl-5-nitrobenzofuran (9) which upon Friedel-Crafts acylation with 4-methoxybenzoyl chloride followed by deprotection of methyl group gives (2).
