  Potent, Selective Tetrahydro-β-carboline Antagonists of the Serotonin 2B (5HT_2B) Contractile Receptor in the Rat Stomach Fundus

  摘要：

  A series of potent, selective 5HT(2B) receptor antagonists has been identified based upon yohimbine, with SAR studies resulting in a 1000-fold increase in 5HT(2B) receptor affinity relative to the starting structure (-log K(B)s > 10.0 have been obtained). These high-affinity tetrahydro-beta-carboline antagonists are able to discriminate among the 5HT(2) family of serotonin receptors, with members of the series showing selectivities of more than 100-fold versus both the 5HT(2A) and 5HT(2C) receptors based upon radioligand binding and functional assays. As the first compounds reported with such selectivity and enhanced receptor affinity, these tetrahydro-beta-carboline antagonists are useful tools for elucidating the role of serotonin acting at the 5HT(2B) receptor in normal and disease physiology.

  In this study, a concise synthetic method of psammaplin A was achieved from 3-bromo-4-hydroxybenzaldahyde and hydantoin through a four-step synthesis via Knoevenagel condensation, hydrolysis, oximation and amidation in 37% overall yield. A collection of novel psammaplin A analogs focused on the variations of substituents at the benzene ring and modifications at the oxime moiety were synthesized. Among
