4-Hydro-2-quinolones. 192.* relationship of xy structure and analgesic activity of 4-amino-2-oxo-1,2-dihydroquinoline-3-carboxylic acids and their derivatives
摘要:
Some 4-N-R-2-Oxo-1,2-dihydroquinoline-3-carboxylic acids and their derivatives were synthesized as close structural analogs of the highly-active analgesic 4-benzylamino-2-oxo-1,2-dihydroquinoline-carboxylic acid. Pharmacological testing showed that manifestation of an analgesic effect depends on the presence of a carboxylic group and benzyl fragment in these molecules.
