“…1 supplemented with 5 mM (or 50 ~tM) L-aspartic acid and 10 ~tM glycine. IEM-1573, IEM-1442, IEM-1441, and IEM-1791 were synthesized by alkylation of the dimethyl ester of imidazole-4,5-dicarboxylic acid followed by hydrolysis, as described in [1]. IEM-1574, IEM-1808, IEM-1795, and IEM-1797 were prepared by oxidation of the corresponding 2-substituted benzimidazoles as described in [2,6,18].…”
