A series of indole-2-carboxylates were prepared and evaluated for their ability to inhibit the binding at the strychnine-insensitive glycine receptor that is associated with the NMDA-PCP-glycine receptor complex. All of the compounds were selective for the glycine site 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 acid (Ki = 1.6 microM vs [3H]glycine), was also found to noncompetitively inhibit the binding of MK-801, a ligand for the phencyclidine site on the receptor macrocomplex. These latter data suggest that the compound functions as an antagonist at the strychnine-insensitive glycine receptor. The structural activity relationships within this series of indole-2-carboxylates is discussed and several key pharmacophores are identified for this series of glycine ligands. In general, the most potent compounds were the C-3 acetamides, with N-propyl-2-carboxy-6-chloro-3-indoleacetamide having the highest receptor affinity.
