Abstract
A new series of 3,4-dihydro-3-amino-2H-1-benzopyran derivatives (1 and 2) bearing various substituents on the 5-position was successfully prepared via palladium-mediated cross-coupling reactions. Some of the new compounds showed high affinity for 5-HT1A and 5-HT7 receptors. The best affinity for the 5-HT1A and 5-HT7 receptors was obtained for 2b (Ki = 0.3 nM for 5-HT1A and 3.1 nM for 5-HT7). The anxiolytic activity of compound 2b was evaluated.
摘要:成功地通过钯介导的交叉偶联反应制备了一系列在5位上带有不同取代基的3,4-二氢-3-氨基-2H-1-苯并吡喃衍生物(1和2)。其中一些新化合物表现出对5-HT1A和5-HT7受体的高亲和力。对于5-HT1A和5-HT7受体的最佳亲和力是2b(5-HT1A的Ki = 0.3 nM,5-HT7的Ki = 3.1 nM)。对化合物2b的抗焦虑活性进行了评估。
