5-Hydroxytryptamine (5-HT)(2C) receptor agonists hold promise for the treatment of obesity. In this study, we describe the in vitro and in vivo characteristics of lorcaserin [(1R)-8-chloro-2,3,4,5-tetrahydro-1-methyl-1H-3 benzazepine], a selective, h

A structure-based search and screen of our compound library identified N-(2-phenoxyethyl)-4-benzylpiperidine (8) as a novel N-methyl-D-aspartate (NMDA) receptor antagonist that has high selectivity for the NR1/2B subunit combination (IC(50) = 0.63 mi

A group of 5-aza-7-substituted-1,4-dihydroquinoxaline-2,3-diones (QXs) and the corresponding 5-(N-oxyaza)-7-substituted QXs were prepared and evaluated as antagonists of ionotropic glutamate receptors. The in vitro potency of these QXs was determined

AMPA receptors can be labeled using the agonist radioligands [3H](R,S)-α-amino-3-hydroxy-5-methylisoxazole-4-propionic acid ([3H](R,S)-AMPA), [3H](S)-AMPA or [3H](S)-5-fluorowillardiine. In the presence of KSCN, [3H](R,S)-AMPA and [3H](S)-AMPA bind

We report on a series of alkyl- and alkoxy-substituted 1,4-dihydroquinoxaline-2,3-diones (QXs), prepared as a continuation of our structure-activity relationship (SAR) study of QXs as antagonists for the glycine site of the N-methyl-D-aspartate (NMDA

The synthesis and SAR of a novel 3-benzazepine series of 5-HT2C agonists is described. Compound 7d (lorcaserin, APD356) was identified as one of the more potent and selective compounds in vitro (pEC50 values in functional assays measuring [(3)H]phosp

4-[4-(4-Benzylpiperidin-1-yl)but-1-ynyl]phenol (8) and 4-[3-(4-benzylpiperidin-1-yl)prop-1-ynyl]phenol (9) are potent NR1A/2B receptor antagonists (IC(50) values 0.17 and 0.10 microM, respectively). Administered intraperitoneally, they both potentiat

Nociceptin (orphanin FQ) is the recently discovered peptide agonist for the orphan receptor opioid receptor-like 1 (ORL1). Despite the high sequence homology between ORL1 and the opioid receptors, most opioids lack affinity for the nociceptin recepto

A series of aromatic and azepine ring-modified analogs of 3-hydroxy-1H-1-benzazepine-2,5-dione (HBAD) were synthesized and evaluated as antagonists at NMDA receptor glycine sites. Aromatic ring-modified HBADs were generally prepared via a Schmidt rea

A series of 1-hydroxy-1,4-dihydroquinoxaline-2,3-diones was synthesized and assayed for NMDA receptor glycine site antagonism. Except for 4a, these were found to be 3–80 times weaker antagonists than the analogous 1,4-dihydroquinoxaline-2,3-diones.
