Aminobicyclo[2.2.1.]heptane dicarboxylic acids (ABHD), rigid analogs of ACPD and glutamic acid: synthesis and pharmacological activity on metabotropic receptors mGluR1 and mGluR2 Original Research Article

Isomeric norbornane-derived rigid analogs mimicking different potential conformations of ACPD (1-aminocyclopentane-1,3-dicarboxylic acid) and glutamic acid have been synthesized, via the hydantoin route, to be used as conformational probes for bioactive conformations at the glutamatergic receptors of the central nervous system. Activities on metabotropic receptors mGluR1 and mGluR2 are reported and discussed.
