Simple synthesis and biological properties of flocoumafen 1 and its structural isomers are described. The key synthetic strategies involve Knoevenagel condensation, Grignard reaction, intramolecular ring cyclization and coupling reaction. Flocoumafen 1 was easily separated into cis and trans forms using flash column chromatography. They were then evaluated for suppression of LPS-induced NO generation
描述了氟考马芬1及其结构异构体的简单合成及其生物学特性。关键的合成策略包括Knoevenagel缩合,Grignard反应,分子内环环化和偶联反应。使用快速柱色谱法可轻松将Flocoumafen 1分离为顺式和反式形式。然后评估它们在体外对LPS诱导的NO生成的抑制作用和抗兴奋性毒性。发现反式氟尿嘧啶在体外浓度为10 µM时可有效抑制NO生成,而对培养的皮层神经元的神经毒性无明显影响。
