superoxide anion from neutrophils results in peripheral tissues damage. Besides, in this study, 2-(3,5-dimethoxyphenoxy)-5,7-dimethoxy-chromen-4-one (4), a 2-phexnoychromone from our compound bank, was demonstrated to have the moderate inhibitory effect on superoxide anion generating. Therefore, serial chromones substituted with phenols or 3-flourothiophenol were designed, synthesized, and examined
中性粒细胞的过度激活与许多炎症性疾病有关。重要的病理机制之一是中性粒细胞产生和胞外释放超氧阴离子导致外周组织损伤。此外,在本研究中,我们的化合物库中的 2-phexnoychromone 2-(3,5-dimethoxyphenoxy)-5,7-dimethoxy-chromen-4-one ( 4 ) 被证明对超氧化物有中等抑制作用。阴离子生成。因此,设计、合成并检查了用苯酚或 3-氟苯硫酚取代的系列色酮对超氧阴离子生成的抑制。根据结果,7 位甲氧基 (R 3) 的色酮,以及苯环中间位点的氢键供体对活性有很大影响。2-(3-氟苯基)硫烷基-7-甲氧基-chromen-4-one ( 16 ) 是从苯酚到苯硫酚的生物电子等排体的成功例子,表现出显着的抗炎作用,IC 50值对抗超氧阴离子生成5.0 ± 1.4 μM。
