  In order to discover novel anti-inflammatory agents, total thirty-seven new resveratrol-based flavonol derivatives were designed and synthesized. All compounds have been screened for their anti-inflammatory activity by evaluating their inhibition effect of LPS-induced NO production in RAW 264.7 macrophages. Their toxicity was also assessed in vitro. Structure-activity relationships (SARs) have been

  为了发现新的抗炎药，设计并合成了总共三十七种新的基于白藜芦醇的黄酮醇衍生物。通过评估其对RAW 264.7巨噬细胞中LPS诱导的NO生成的抑制作用，筛选了所有化合物的抗炎活性。他们的毒性也进行了体外评估。总结了结构-活性关系（SAR），最后发现2-（2,4-二甲氧基-6-（4-甲氧基苯乙烯基）苯基）-3-羟基-4H-铬-4-基团最活跃低毒的脚手架。该化合物可通过IC 50显着降低NO，IL-6和TNF-α的产生在RAW 264.7巨噬细胞中分别为1.35、1.12和1.92μM。初步的机制研究表明，它可以抑制TLR4蛋白的表达，从而激活NF-ĸB细胞信号通路。该化合物的体内抗炎活性可以通过LPS诱导的急性肺损伤（ALI）小鼠模型减轻肺部炎症。我们相信这些发现将进一步支持更有效的急性肺损伤调节抑制剂合理设计的研究。

  acetylcholinesterase (AChE) and a series of antioxidant flavonoid analogs were studied by fluorescence spectroscopic assay. The present study incorporated different classes of naturally occurring and synthetic flavonoid compounds like flavones, isoflavones, and chalcones as well as a few standard antioxidants. The AChE inhibitory (AChEI) activity of these compounds was further analyzed using in silico techniques

  activation of six‐membered compounds is reported. The Ru‐catalyzed reaction of 3‐hydroxy‐2‐phenyl‐chromones with alkynes works most efficiently in the presence of the ligand PPh3 to provide spiro‐indenebenzofuranones. Unlike previously reported metal‐catalyzed decarbonylative annulation reactions, in the present decarbonylative annulation reaction, the annulation occurs before extrusion of carbon monoxide

  A facile and efficient synthetic strategy to 3-((trifluoromethyl)thio)-4H-chromen-4-one was developed. AgSCF3 and trichloroisocyanuric acid were employed here to generate active electrophilic trifluoromethylthio species in situ.
