The synthesis and evaluation of a novel series of 1,7-cyclized indole-based human adrenergic receptor (beta3-AR) agonists are reported. The synthesis of a variety of 1,7-cyclized indole part was accomplished by the Mitsunobu reaction or a ring closing metathesis (RCM) reaction. SAR studies revealed that expansion of the ring size resulted in considerable selectivity against the beta1- and beta2-ARs
合成和评估的新型系列的1,7环吲哚为基础的人肾上腺素能受体(β3-AR)激动剂。各种1,7-环化的吲哚部分的合成是通过Mitsunobu反应或闭环复分解(RCM)反应完成的。SAR研究表明,环尺寸的扩大导致对beta1-和beta2-AR的相当大的选择性。发现化合物26是八元环类似物,在其1,7-连接子部分具有双键,是一种有效的β3-AR激动剂(EC50 = 0.75 nM,IA = 90%),对β3的选择性非常高-AR超过beta1和beta2-AR。
