  Antagonism of 1-(2,5-dimethoxy-4-methylphenyl)-2-aminopropane stimulus with a newly identified 5-HT2- versus 5-HT1C-selective antagonist

  摘要：

  DOM [i.e., 1-(2,5-dimethoxy-4-methylphenyl)-2-aminopropane] is a 5-HT1C/2 serotonin agonist that exerts stimulus control of behavior in animals. In order to determine if the discriminative stimulus effect of DOM is 5-HT1C- or 5-HT2-mediated, it would be informative to conduct tests of stimulus antagonism with a 5-HT1C- or 5-HT2-selective antagonist. To date, no such agents exist. Although the neuroleptic agent spiperone binds at D2 dopamine receptors and 5-HT1A serotonin receptors, (a) it displays about a 1000-fold selectivity for 5-HT2 versus 5-HT1C sites and (b) it has been used as a ''5-HT2-selective'' antagonist. Because spiperone is a behaviorally disruptive agent, it is not suitable for use in drug-discrimination studies. Using the spiperone molecule as a starting point, a limited structure-affinity investigation was conducted in order to identify a suitable antagonist with high affinity and selectivity for 5-HT2 receptors, and yet an antagonist that might lack the disruptive actions of spiperone. Various modifications of the spiperone molecule were examined, but most resulted in decreased 5-HT2 affinity or in loss of selectivity. One compound, 8-[3-(4-fluorophenoxy)propyl]-1-phenyl-1,3,8-triazaspiro[4.5]decan-4-one(26), was shown to bind at 5-HT2 sites with high affinity (K(i) = 2 nM) and >2,000-fold selectivity versus 5-HT1C sites. In tests of stimulus antagonism using rats trained to discriminate 1 mg/kg of DOM from saline vehicle, 26 behaved as a potent antagonist (ED50 = 0.003 mg/kg) and lacked the disruptive effects associated with spiperone. As such, (a) it would appear that the DOM stimulus is primarily a 5-HT2-mediated, and not 5-HT1C-mediated, phenomenon, and (b) compound 26 may find application in other pharmacologic investigations where spiperone may not be a suitable antagonist.

  A series of novel acylsulfonamide, acylsulfamide, and sulfonylurea bioisosteres of carboxylic acids were prepared as CXCR2 antagonists. Structure-activity relationships are reported for these series. One potent orally bioavailable inhibitor had excellent PK properties and was active in a lung injury model in hyperoxia-exposed newborn rats. (C) 2008 Elsevier Ltd. All rights reserved.
