structural similarity of our previous 5-HT2C agonists with the melatonin receptor agonist tasimelteon and the putative biological cross-talk between serotonergic and melatonergic systems, a series of new (2,3-dihydro)benzofuran-based compounds were designed and synthesized. The compounds were evaluated for their selectivity toward 5-HT2A, 5-HT2B, and 5-HT2C receptors in the calcium flux assay with the
基于我们先前的5-HT 2C激动剂与褪黑激素受体激动剂tasimelteon的结构相似性以及血清素能和褪黑素能系统之间的假定生物学相互作用,我们开发了一系列新的基于(2,3-二氢)苯并呋喃的化合物设计和合成。在钙通量测定中评估了化合物对5-HT 2A,5-HT 2B和5-HT 2C受体的选择性,最终目的是生成选择性5-HT 2C激动剂。通过比较它们在G蛋白信号通路与β-arrestin募集时的转导效率,研究了所选化合物的功能选择性。最具功能选择性的化合物(+)- 7e与血清素相比,在钙通量和磷酸肌醇(PI)水解试验中,β-arrestin的募集作用较弱,并且受体脱敏性也较低。我们首次报道具有弱β-arrestin募集的选择性5-HT 2C激动剂可以产生独特的受体脱敏特性。
