ImmH (1) and DADMe-ImmH (2) are potent inhibitors of human purinenucleoside phoshorylase (PNP), developed by us and currently in clinical trials for the treatment of a variety of T-cell related diseases. Compounds1 and 2 were used as templates for the design and synthesis of a series of acyclic immucillin analogues (8−38) in order to identify simplified alternatives to 1 and 2. SerMe-ImmG (8) and

(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.

Novel intermediates for non-ionic polyiodo amino-substituted benzenepolyamides having polyol substituents on the amide nitrogens are provided which are 5-amino-6-hydroxy-1,3-dioxepanes. The compounds provide an economic and efficient route to novel contrast media having excellent chemical and physiological properties. Also provided are methods for preparing the subject compounds.
