describe the synthesis of novel tricyclic analogues issued from the rigidification of the methoxy group of the benzofuranic analogue of melatonin as MT1 and MT2 ligands. Most of the synthesized compounds displayed high binding affinities at MT1 and MT2 receptors subtypes. Compound 6b (MT1, Ki = 0.07 nM; MT2, Ki = 0.08 nM) exhibited with the vinyl 6c and allyl 6d the most interesting derivatives of this
在这里,我们描述了由褪黑激素的苯并呋喃类似物的MT 1和MT 2配体的甲氧基的刚性化而发出的新型三环类似物的合成。大多数合成的化合物在MT 1和MT 2受体亚型上显示出高结合亲和力。化合物6b(MT 1,K i = 0.07nM; MT 2,K i = 0.08nM)与乙烯基6c和烯丙基6d一起显示出该系列中最令人感兴趣的衍生物。这些化合物的功能活性在EC 50下显示出完全的激动剂活性在纳摩尔范围内。化合物6a(EC 50 = 0.8 nM,E max = 98%)和6b(EC 50 = 0.2 nM,E max = 121%)表现出良好的药理作用。
