  An Improved Large-Scale Preparation of Benzimidazole-2-Sulfonic Acids and 2-Chlorobenzimidazoles.‡

  摘要：

  An improved method for the preparation of benzimidazole-2-sulfonic acids from 2-mercaptobenzimidazoles has been developed which utilizes aqueous sodium percarbonate. 2-Chlorobenzimidazoles were obtained in high yield from the corresponding sulfonic acids upon reaction with PCl5 in POCl3 on a gram-mole scale.

  Benzimidazoles as NMDA Glycine-Site Antagonists: Study on the Structural Requirements in 2-Position of the Ligand

  摘要：

  A series of different substituted benzimidazole derivatives has been synthesized and evaluated for the ability to displace [3H]MDL-105,519 to rat cortical membranes. Two benzimidazole-2-carboxylic acids 9 b and 9 c, in this substitution pattern not yet described as glycine antagonists, showed IC50 values of 0.89 microM (9 b) and 38.0 microM (9 c). Replacement of the carboxylate function in 2-position by a sulfonic acid moiety appreciably increased solubility, but decreased the affinity giving evidence for the strong need of the carboxylate group within the ligand. Further structure-activity studies using benzimidazole-2-one derivatives with an acetic acid moiety adjacent to a ring nitrogen revealed new insights into the importance of amide functionalities within the heterocycle for the affinity of antagonist glycine-site ligands.
