The syntheses and anti-inflammatory activities of novel thieno[2, 3-b]pyridine and thieno[2, 3-b : 5, 4-c']-dipyridine derivatives are desrcibed. These compounds were designed by modification of the quinoline template of a new type of disease-modifying antirheumatic drug (DMARD), TAK-603, and prepared by the Friedlander reaction as a key reaciton. Their anti-inflammatory effects were evaluated using an adjuvant arthritis rat model. Most of the compounds which included a dithylamino moiety in the side chain had potent anti-inflammatory effect. In particular, ethyl 2-(diethylaminomethyl)-4-(3, 4-dimethoxyphenyl)thieno[2, 3-b : 5, 4-c']dipyridine-3-carboxylate (21) exhibitied more potent activity than TAK-603.
描述了新型噻吩[2, 3-b]吡啶和噻吩[2, 3-b : 5, 4-c']-二吡啶衍生物的合成及其抗炎活性。这些化合物是通过对一种新型疾病修饰抗风湿药物(DMARD)TAK-603的喹啉模板进行改造而设计的,并通过弗里德兰德反应作为关键反应进行制备。使用加佐剂性关节炎大鼠模型评估了它们的抗炎效果。大多数包含二乙氨基基团的侧链化合物具有显著的抗炎效果。特别是,乙基2-(二乙氨基甲基)-4-(3, 4-二甲氧基苯基)噻吩[2, 3-b : 5, 4-c']二吡啶-3-羧酸酯(21)表现出比TAK-603更强的活性。
