A new series of novel benzimidazole derivatives containing substituted pyrid-2-yl moiety and polyhydroxy sugar conjugated to the N-benzimidazole moiety has been synthesized and evaluated as orally bioavailable anti-inflammatory agents with anti-ulcerogenic activity. The anti-inflammatory and anti-ulcerogenic activities of these compounds were compared to diclofenac and omeprazole, respectively. In
合成了一系列新的含有取代的吡啶-2-基部分和与N-苯并咪唑部分缀合的多羟基糖的新型苯并咪唑衍生物,并将其评价为具有抗溃疡活性的口服生物利用型抗炎药。将这些化合物的抗炎和抗溃疡活性分别与双氯芬酸和奥美拉唑进行了比较。在角叉菜胶诱发的爪水肿测定中,2-甲基-N -((3,4-二甲氧基吡啶-2-基)甲基)-1 H-苯并咪唑-5-胺(12d)和1-(1,2,3, 5-四羟基-α - d-甘露呋喃糖)-5-((((3,4-二甲氧基吡啶-2-基)甲基)氨基)-2-甲基-1 H-苯并咪唑(15d)通过减少炎症分别显示62%和72%的剂量依赖性抗炎活性,这与双氯芬酸(73%)相当。与双氯芬酸相反,这些化合物的抗炎活性不仅对胃粘膜没有任何副作用,而且在大鼠幽门结扎和乙醇诱发的胃溃疡模型中显示出显着的抗溃疡活性,类似于奥美拉唑。总之,这些发现表明12d和15d是有效的抗炎剂,同时具有抗溃疡作用,并支持其作为炎
