- Synthesis, in vitro pharmacology, and structure-activity relationships of 2-aminobicyclo[3.1.0]hexane-2,6-dicarboxylic acid derivatives as mGluR2 antagonists
-
Chemical modification of the bicyclo[3.1.0]hexane ring C-3 position led to the discovery of 3-alkoxy-2-aminobicyclo[3.1.0]hexane-2,6-dicarboxylic acid, 3-benzylthio-, and 3-benzylamino-2-amino-6-fluorobicyclo[3.1.0]hexane-2,6-dicarboxylic acid derivatives, metabotropic glutamate receptor 2 (mGluR2) antagonists. In particular, 3-(3,4-dichlorobenzyloxy)-2-aminobicyclo[3.1.0]hexane-2,6-dicarboxylic acid (15ae), (1R,2S,5R,6R)-2-amino-3-(3,4-dichlorobenzylthio)-6-fluorobicyclo[3.1.0]h exane-2,6-carboxylic acid (15at), and (1R,2S,5R,6R)-2-amino-3-(N-(3,4-dichlorobenzylamino))-6-fluorobicyclo[3. 1.0]hexane-2,6-carboxylic (15ba) showed high affinity for the mGluR2 receptor (15ae: Ki = 2.51 nM, 15at: Ki = 1.96 nM, and 15ba: Ki = 3.29 nM) and potent antagonist activity for mGluR2 (15ae; IC50 = 34.21 nM, 15at; IC50 = 13.34 nM, and 15ba; IC50 = 35.96 nM). No significant agonist activity for mGluR2 was observed with 15ae, 15at, or 15ba. This paper reports on the synthesis, in vitro pharmacological profile, and structure-activity relationships (SARs) of 3-substituted-2-aminobicyclo[3.1.0]hexane-2,6-dicarboxylic acid.
