The selective and systemically active antagonist for the metabotropic glutamate receptor subtype 5 (mGluR5), 2-methyl-6-(phenylethynyl)pyridine (MPEP) was shown to display anxiolytic-like activity in a number of unconditioned assays of stress and anxiety (elevated plus maze, shock probe burying, marble burying, social interaction, and stress-induced(More)
Recent data has suggested that the 5-hydroxytryptamine (5-HT)(1A) receptor is involved in cognitive processing. A novel 5-HT(1A) receptor antagonist, 4-cyano-N-{2R-[4-(2,3-dihydrobenzo[1,4]-dioxin-5-yl)-piperazin-1-yl]-propyl}-N-pyridin-2-yl-benzamide HCl (lecozotan), which has been characterized in multiple in vitro and in vivo pharmacological assays as a(More)
The pharmacological profile of WAY-163909 [(7bR, 10aR)-1,2,3,4,8,9,10,10a-octahydro-7bH-cyclopenta-[b][1,4]diazepino[6,7,1hi]indole], a novel 5-hydroxytryptamine (HT)(2C) (serotonin) receptor-selective agonist is presented. WAY-163909 displaced [(125)I]2,5-dimethoxy-4-iodoamphetamine binding from human 5-HT(2C) receptor sites, in Chinese hamster ovary (CHO)(More)
Galanin's influence on monoaminergic neurotransmission, together with its discrete CNS distribution in corticolimbic brain areas, points to a potential role for this neuropeptide in mediating anxiety- and depression-like responses. To evaluate this hypothesis, the non-selective galanin receptor agonist, galnon, was tested in multiple preclinical models of(More)
A series of 2,3,4,4a-tetrahydro-1H-pyrazino[1,2-a]quinoxalin-5-(6H)ones and 2,3,4,4a,5,6-hexahydro-1H-pyrazino[1,2-a]quinoxalines was shown to exhibit 5-HT2C agonist binding and functional activity. Compound 21R inhibited food intake over 2 h in fasted, male Sprague Dawley rats with ED50 values of 2 mg/kg (i.p.) and 10 mg/kg (p.o.).
A series of benzodioxanylpiperazine derivatives possessing a 4-aryl amide substituent was prepared and evaluated for 5-HT(1A) affinity and functional antagonist activity in vitro and in vivo. All of the compounds in this series possessed high affinity for the human 5-HT(1A) receptor and many displayed potent antagonist activity in vitro and varying degrees(More)
Perzinfotel [EAA-090; [2-(8,9-dioxo-2,6-diazabicyclo[5.2.0]non-1(7)-en-2-yl)-ethyl]phosphonic acid] is a selective, competitive N-methyl-D-aspartate (NMDA) receptor antagonist with high affinity for the glutamate site. The current study evaluated whether perzinfotel would have antinociceptive effects or block thermal hypersensitivity associated with the(More)
The startle reflex is an unconditioned, quantifiable behavior used to study sensory modalities. We examined whether the acoustic startle reflex (ASR) was sensitive to lesions induced by focal cerebral ischemia. Sprague-Dawley rats were pre-screened for startle reflex responses 3-6 days prior to surgery and there were no differences in mean startle amplitude(More)
