of potent adhesion molecule inhibitors. Of these, (anti) [3-(10H-pyrazino[2,3-b][1,4]benzothiazin-8-yl)methyl-3-azabicyclo[3.3.1]non-9-yl]acetic acid 2q (ER-49890), showed the most potent oral inhibitory activities against neutrophil migration in an interleukin-1 (IL-1) induced paw inflammation model using mice, and leukocyte accumulation in a carrageenan pleurisy model in the rat, and therapeutic effect
制备了10H-吡嗪并[2,3-b] [1,4]苯并噻嗪的新型哌啶羧酸衍生物,并评价了其对粘附分子如细胞间粘附分子-1(ICAM-1)上调的抑制活性。用含有羧酸的部分取代先前制备的衍生物的哌啶环上的甲磺酰基基团产生了许多有效的粘附分子抑制剂。其中,(反)[3-(10H-吡嗪并[2,3-b] [1,4]苯并噻嗪-8-基)甲基-3-氮杂双环[3.3.1]非-9-基]乙酸2q (ER-49890)在使用小鼠的白介素1(IL-1)诱导的爪炎症模型中显示出对中性粒细胞迁移的最强口服抑制活性,在大鼠角叉菜胶胸膜炎模型中显示了白细胞积累以及对胶原蛋白的治疗作用诱发的大鼠关节炎。
