A series of 2-(aminomethyl)chromans (2-AMCs) was synthesized and evaluated for their affinity and selectivity for both the high- and low-affinity agonist states (D2High and D2Low, respectively) of the dopamine (DA) D2 receptor. The 7-hydroxy-2-(aminomethyl)chroman moiety was observed to be the primary D2 agonist pharmacophore. The 2-methylchroman moiety was… (More)
Compounds containing a 5-carbamoyl-8-fluoro-3-amino-3,4-dihydro-2H-1-benzopyran and a 3-alkylindole moiety linked through a common basic nitrogen were prepared and evaluated for 5-HT1A affinity, serotonin rat transporter affinity, and functional antagonist activity in vitro. 26a was found to be the most potent and selective compound in this series and was… (More)
Comparative molecular field analysis (CoMFA) has been applied to novel D2 partial agonists. Due to the predictability of the CoMFA model across different series of D2 partial agonists, we believe these compounds are binding to the D2 agonist receptor in the conformation and alignment described herein.
Described in this report is a systematic study which led to the identification of two new dopamine D2 partial agonists (5 and 17). Phenols 5 and 17 represent prototypes of two new classes of D2 partial agonists as well as templates for the future design of novel dopaminergic agents.
Based on the previously reported discovery lead, 3-(cis-4-(4-(1H-indol-4-yl)piperazin-1-yl)cyclohexyl)-5-fluoro-1H-indole (2), a series of related arylpiperazin-4-yl-cyclohexyl indole analogs were synthesized then evaluated as 5-HT transporter inhibitors and 5-HT(1A) receptor antagonists. The investigation of the structure-activity relationships revealed… (More)
The design and synthesis of a novel series of indole derivatives (9) having dual 5-HT transporter reuptake and 5-HT(1A) antagonist activity are described.
Derivatives of the serotonin reuptake inhibitor 4-(5-fluoro-1H-indol-3-yl)cyclohexylamine, in which serotonin 1A (5-HT(1A)) receptor pharmacophoric elements are incorporated, are reported. Analogs exhibiting affinity for both the serotonin transporter and the 5-HT(1A) receptor are described. Compounds containing 1-(4-indolyl)piperazine and… (More)
The synthesis of several bioisosteric analogs based on the 3-OH-phenoxyethylamine dopamine D2 agonist template (i.e., 3) is described. The benzimidazol-2-ones and benzthioimidazol-2-ones (7-10) and 2-trifluoromethyl-benzimidazole (13) were observed to have excellent affinity for the D2 receptor.
