We report herein an efficient synthesis of 2-substituted furo[3,2-b]pyridines and their biological evaluation as melatonin receptors ligands. The proposed eight-step sequence ending with a Suzuki coupling allowed a rapid access to various analogues. The steric hindrance and the conformation of the aryl group in C2-position were evaluated regarding the selectivity of the molecule for one of the two
我们在这里报告了2-取代的呋喃并[3,2- b ]吡啶的有效合成及其作为褪黑激素受体配体的生物学评估。所提出的以Suzuki耦合结尾的八步序列允许快速访问各种类似物。关于分子对两个高亲和性褪黑激素受体之一的选择性和化合物的活性曲线,评估了C 2位的空间位阻和芳基的构象。就选择性而言,引入1-萘基取代基具有最好的结果,MT 1 / MT 2比为约150(MT 1 K i = 198 nM,MT 2 K i = 1.3 nM)。
