Novel non-ionic contrast media of a hitherto unknown combination of low osmolality and low viscosity are efficiently prepared from generally available ionic contrast media or non-iodinated precursors. Particularly, polyhydroxyhalo-hydrocarbons are employed with a triiodo-substituted acylamido benzoic acids in aqueous weakly basic media to selectively substitute the amido nitrogen, followed by activation of the carboxyl group for amide formation.

(EN) Novel non-ionic contrast media are efficiently prepared from generally available ionic contrast media or non-iodinated precursors. Particularly, polyhydroxyhalo-hydrocarbons are employed with a triiodo-substituted acylamido benzoic acids in aqueous weakly basic media to selectively substitute the amido nitrogen, followed by activation of the carboxyl group for amide formation.(FR) De nouveaux milieux de contraste non-ioniques sont préparés de manière efficiente à partir de milieux de contraste ioniques couramment disponibles ou à partir de précurseurs non-iodés. On utilise notamment des polyhydroxyhalo-hydrocarbures avec des acides acylamido benzoïques à substitution triiodo dans des milieux aqueux faiblement basiques pour substituer de manière sélective l'azote amido, cette opération étant suivie par l'activation du groupe carboxyle pour la formation d'amides.

The invention relates to compounds of the general formula (I) which are inhibitors of purine nucleoside phosphorylases (PNPs) and/or nucleoside hydrolases (NHs). The invention also relates to the use of these compounds in the treatment of diseases and infections including cancer, bacterial infections, protozoal infections, and T-cell mediated disease and to pharmaceutical compositions containing the compounds.
Es werden neuartige Triiod-5-Aminoisophthaldiamide angegeben, bei denen die Amino- und eine der Amid-Stickstoffgruppen substituiert sind. Die Verbindungen besitzen mindestens zwei Hydroxylgruppen und weisen niedrige Viskosität und Osmolalität auf. Es werden verfahren für die Herstellung der Verbindungen angegeben.
