A series of benzimidazol-2-ylamides of 4-hydroxy-2-oxo-1,2-dihydroquinoline-3-carboxylic acids was prepared in a search for biologically active compounds. These compounds exist in the crystal exclusively in the amide form, while in solution amide↔imide tautomerism is observed. The results of a study of the antithyroid and antituberculosis activities of these compounds are given.
为了寻找
生物活性化合物,制备了一系列
