their ability to inhibit the binding at the strychnine-insensitiveglycinereceptor that is associated with the NMDA-PCP-glycine receptorcomplex. All of the compounds were selective for the glycinesite relative to other sites on the receptor macrocomplex and several of the compounds in this series were found to have submicromolar affinity for this receptor. The lead compound, 2-carboxy-6-chloro-3-indoleacetic
