possess significant antidepressant properties. This biological activity was found to be at a maximum among those compounds bearing an ortho substituent (e.g., NH2 as in 1) in the pendant aryl ring. In order to explore further this "ortho effect", we synthesized cyclic analogues of type 3 and 4 in which the position of the o-NH2-substituted aryl group is conformationally restricted and defined. When tested
据我们报道,先前描述的一系列1-芳基螺[吲哚啉-3,4'-哌啶] s具有显着的抗抑郁特性。发现该生物活性在芳基侧基环上带有邻位取代基(例如,如1中的NH 2)的那些化合物中最大。为了进一步探讨这种“邻位效应”,我们合成了类型3和4的环状类似物,其中邻-NH 2-取代的芳基的位置在构象上受到限制和定义。当通过预防丁苯那嗪上睑下垂在小鼠中测试抗抑郁活性时,发现这些刚性类似物中邻氨基苯基侧基的旋转受限导致抗抑郁特性的丧失。但是,这种分子限制使止痛活性得以保留,甚至得到改善。
