The present invention relates to Pyridin-2-yl sulfanyl acid ester compounds having antiinflammatory properties. The present invention particularly relates to novel anti-inflammatory heterocyclic acid esters of Pyridin-2-yl sulfanyl having the structure of general formula 1 which have been screened for their antiinflammatory activity with respect to inhibition of adhesion of neutrophils, isolated from human peripheral blood, onto the surface of human umbilical vein endothelial cells (HUVEC) as a result of inhibition of the cytokine-stimulated expression of cell adhesion molecule ICAM-1. The compound RS-Z, 3-(Pyridin-2-yl sulfanyl)-propionic acid pentyl ester (structure la, R1 = H, R2 = H, R3 = CH2COOC5H11) was found to be most effective for ICAM-1 and neutrophil adhesion inhibition and was found to effectively alleviate inflammation mediated by excessive leukocyte infiltration leading to inflammatory disorders or like conditions, such as acute lung injury and acute respiratory distress syndrome in mice.
本发明涉及具有抗炎性质的吡啶-2-基巯酸酯化合物。本发明特别涉及一类新型的抗炎杂环酸酯,其具有通用公式1的结构,并且已经通过抑制从人外周血中分离的中性粒细胞粘附到人脐静脉内皮细胞(HUVEC)表面的能力来筛选其抗炎活性,这是通过抑制细胞粘附分子ICAM-1的细胞因子刺激表达的结果。发现化合物RS-Z,3-(吡啶-2-基巯基)-丙酸戊酯(结构la,R1 = H,R2 = H,R3 = CH2COOC5H11)对ICAM-1和中性粒细胞粘附抑制最有效,并且发现它有效地缓解了由过度白细胞浸润导致的炎症介导的炎症疾病或类似状况,例如小鼠的急性肺损伤和急性呼吸窘迫综合征。
