• 4-(Phosphonoalkyl)- and 4-(phosphonoalkenyl)-2-piperidinecarboxylic acids: synthesis, activity at N-methyl-D-aspartic acid receptors and anticonvulsant activity

  A series of 4-(phosphonoalkyl)- and 4-(phosphonoalkenyl)-2-piperidinecarboxylic acids were synthesized, and their biological activity was assessed as competitive ligands for the NMDA receptor, both in vitro by using a receptor binding assay ([3H]CGS 19755 binding) and in vivo by using an NMDA seizure model in mice. The analogues were also evaluated in [3H]AMPA and [3H]kainate binding to assess their affinity for non-NMDA excitatory amino acid receptor subtypes. A number of these analogues show potent and selective NMDA antagonistic activity both in vitro and in vivo. Most notable are 4-(phosphonomethyl)-2-piperidinecarboxylic acid (1a) (CGS 19755) and the phosphonopropenyl analogue 1i, both of which show anticonvulsant activity in the 1-2 mg/kg ip range. With the aid of computer-assisted modeling, a putative bioactive conformation for AP-5 is hypothesized from the SAR data presented and a preliminary model for the antagonist-preferring state of the NMDA receptor is presented.
