Simple synthesis of modafinil derivatives and their biological activity are described. The key synthetic strategies involve substitution and coupling reactions. We determined the anti-inflammatory effects of modafinil derivatives in cultured BV2 cells by measuring the inhibition of nitrite production and expression of iNOS and COX-2 after LPS stimulation. It was found that for sulfide analogues introduction of aliphatic groups on the amide part (compounds 11a–d) resulted in lower anti-inflammatory activity compared with cyclic or aromatic moieties (compounds 11e–k). However, for the sulfoxide analogues, introduction of aliphatic moieties (compounds 12a–d) showed higher anti-inflammatory activity than cyclic or aromatic fragments (compounds 12e–k) in BV-2 microglia cells.
描述了莫达非尼衍生物的简单合成及其生物活性。关键的合成策略包括取代反应和偶联反应。我们通过测量在LPS刺激后硝酸盐产生的抑制和iNOS及COX-2的表达,确定了莫达非尼衍生物在培养的BV2细胞中的抗炎效果。研究发现,对于硫化物类似物,在酰胺部分引入脂肪族基团(化合物11a–d)导致其抗炎活性低于环状或芳香族部分(化合物11e–k)。然而,对于亚磺酸酯类似物,引入脂肪族部分(化合物12a–d)在BV-2小胶质细胞中显示出比环状或芳香族片段(化合物12e–k)更高的抗炎活性。
