E-selectin, ICAM-1, or VCAM-1 on human vascular endothelial cells. Traditional medicinal chemistry methods were applied to this low-micromolar inhibitor, resulting in the 2,4-disubstituted thieno[2,3-c]pyridine A-205804, a potent and selective lead inhibitor of E-selectin and ICAM-1 expression (IC(50) = 20 and 25 nM, respectively). The relative position of the nitrogen atom in the thienopyridine isomer
炎症级联反应中的一个关键的早期事件是在血管内皮细胞腔表面诱导细胞粘附分子表达。这些粘附分子包括E-选择素,ICAM-1和VCAM-1,它们可将循环白细胞募集到炎症部位。这些粘附相互作用使白细胞牢固地粘附并穿过血管内皮并迁移到组织损伤部位。可以预期将阻止一种或多种细胞粘附分子在内皮上的诱导表达的药物提供减弱与慢性炎性疾病有关的炎性反应的新机制。噻吩并[2,3-d]嘧啶,A-155918,从全细胞高通量分析中可以鉴定出抑制肿瘤坏死因子-α(TNFalpha)诱导的人血管内皮细胞上E-选择蛋白,ICAM-1或VCAM-1表达的化合物。将传统药物化学方法应用于这种低微摩尔抑制剂,产生2,4-二取代噻吩并[2,3-c]吡啶A-205804,这是一种有效的选择性E-选择素和ICAM-1表达的先导抑制剂( IC(50)分别为20和25 nM)。已显示噻吩并吡啶异构体中氮原子的相对位置对活性至关重要,小的
