1,3-bis-(3-(mono- or poly-hydroxy)acylamino-5-(mono- or poly-hydroxyalkyl)aminocarbonyl-2,4,6-triiodo-benzoyl-amino) -hydroxy- or hydroxyalkyl-propanes, their methods of preparation and X-ray contrast media containing them

摘要

Symmetrical or asymmetrical 1,3-bis-[3-(mono- or poly-hydroxy)acylamino-5-(mono- or polyhydroxyalkyl)-aminocarbonyl-2,4,6-triiodo-benzoyl-amino]-hydroxy- or hydroxyalkyl-propanes, useful to constitute the opacifying component of X-ray contrast media, are described.
