Abstract
Description
Foreliggende oppfinnelse vedrører forbindelser som kan anvendes som kontrastmidler for radiografi. The present invention relates to compounds that can be used as contrast agents for radiography.
Oppfinnelsen vedrører også kontrastmidler inneholdende de samme forbindelser. The invention also relates to contrast agents containing the same compounds.
Jodbenzenforbindelser som inneholder flere'jodatomer i benzen-ringen, vanligvis 3 jodatomer pr benzenring, og forskjellige andre substituenter har i lengre tid vært anvendt som kontrastmidler. Disse andre substituenter er farmakologisk tålbare grupper som gjør at forbindelsene kan tilføres til mennesker og dyr. Generelt velges disse substituenter, på den ene side, for å gi forbindelsene passende oppløselighet i vann slik at de kan tilføres i vandig oppløsning og, på den annen side, for å gi disse forbindelser en toleranse som er til-strekkelig for deres anvendelse i humane organismer. Iodobenzene compounds containing several iodine atoms in the benzene ring, usually 3 iodine atoms per benzene ring, and various other substituents have for a long time been used as contrast agents. These other substituents are pharmacologically tolerable groups which enable the compounds to be administered to humans and animals. In general, these substituents are chosen, on the one hand, to give the compounds suitable solubility in water so that they can be administered in aqueous solution and, on the other hand, to give these compounds a tolerance sufficient for their use in humans organisms.
For dette formål er ikke-ioniske strukturer foreslått, dvs. jodbenzenderivater med ikke-ioniske substituenter. For this purpose, non-ionic structures have been proposed, i.e. iodobenzene derivatives with non-ionic substituents.
I patentet FR-A-2 053 037 ble således karbamoyljodbenzenfor-bindelser som totalt inneholder minst en N-hydroksyalkyl-gruppe og minst to hydroksygrupper foreslått. Thus, in the patent FR-A-2 053 037, carbamoyl iodobenzene compounds containing a total of at least one N-hydroxyalkyl group and at least two hydroxy groups were proposed.
En forbindelse som illustrerer denne gruppen er metrizamid som imidlertid har vist seg å ha begrenset stabilitet. A compound that illustrates this group is metrizamide which, however, has been shown to have limited stability.
I EPO patentsøknad nr 89 401 509.8 ble det foreslått ikke-ioniske forbindelser som tolereres godt av den humane organ-isme og som utviser god stabilitet i vandig oppløsning. Disse forbindelser har formelen: In EPO patent application no. 89 401 509.8, non-ionic compounds were proposed which are well tolerated by the human organism and which exhibit good stability in aqueous solution. These compounds have the formula:

polyhydroksyalkyl, polyhydroxyalkyl,
R3 er valgt fra hydrogen eller C-^-C^ alkyl, og R 3 is selected from hydrogen or C 1 -C 4 alkyl, and
R4 er valgt fra hydrogen, C^-C^ alkyl, C1-C4 hydroksyalkyl R 4 is selected from hydrogen, C 1 -C 4 alkyl, C 1 -C 4 hydroxyalkyl
eller C-^- C^ polyhydroksyalkyl. or C 1 -C 3 polyhydroxyalkyl.
Formålet med den foreliggende oppfinnelse er å tilveiebringe nye forbindelser som tilhører gruppen av forbindelser med formel I, som er kjennetegnet ved både god stabilitet og god oppløselighet i vandig medier. The purpose of the present invention is to provide new compounds belonging to the group of compounds with formula I, which are characterized by both good stability and good solubility in aqueous media.
Forbindelsene i henhold til den foreliggende oppfinnelse har den følgende generelle formel: The compounds according to the present invention have the following general formula:
hvori R velges fra 2,3-dihydroksypropyl og 1,3-dihydroksy-2-propyl. wherein R is selected from 2,3-dihydroxypropyl and 1,3-dihydroxy-2-propyl.
En av forbindelsene i henhold til den foreliggende oppfinnelse er 5-[3-hydroksy-2-(hydroksymetyl)-propionamido]-N,N'-dimetyl-N,N'-bis-(2,3-dihydroksypropyl)-2,4,6-trijodisoftalamid, dvs. forbindelsen med formelen: One of the compounds according to the present invention is 5-[3-hydroxy-2-(hydroxymethyl)-propionamido]-N,N'-dimethyl-N,N'-bis-(2,3-dihydroxypropyl)-2, 4,6-triiododisophthalamide, i.e. the compound with the formula:
Den andre forbindelse i henhold til den foreliggende oppfinnelse er 5-[3-hydroksy-2-(hydroksymetyl)-propionamido]-N,N'-dimetylN,N'-bis-(1,3-dihydroksy-2-propyl)-2,4,6-trijodiso-ftalamid, med formelen: The second compound according to the present invention is 5-[3-hydroxy-2-(hydroxymethyl)-propionamido]-N,N'-dimethylN,N'-bis-(1,3-dihydroxy-2-propyl)- 2,4,6-triiododiso-phthalamide, with the formula:
Disse formler dekker ikke bare racematene men også alle de stereoisomerer som er forbundet med tilstedeværelsen av asym-metrisk karbon og med hindring av rotasjon av visse bindinger som skyldes den steriske hindring tilveiebragt av jodatomene. These formulas cover not only the racemates but also all the stereoisomers associated with the presence of asymmetric carbon and with the hindrance of rotation of certain bonds due to the steric hindrance provided by the iodine atoms.
Forbindelsen med formel A er uventet kjennetegnet ved en bedre oppløselighet i et vandig medium enn forbindelsen i eks. 1 i den ovennevnte EPO patentsøknad, nemlig 5-[3-hydroksy-2- The compound with formula A is unexpectedly characterized by a better solubility in an aqueous medium than the compound in ex. 1 in the above-mentioned EPO patent application, namely 5-[3-hydroxy-2-
(hydroksymetyl)-N-(2,3-dihydroksypropyl)propionamido]-N',N"-bis-(2-hydroksyetyl)-2,4,6-trijodisoftalamid. (hydroxymethyl)-N-(2,3-dihydroxypropyl)propionamido]-N',N"-bis-(2-hydroxyethyl)-2,4,6-triiododisophthalamide.
Videre har forbindelsene i henhold til den foreliggende oppfinnelse den fordel sammenlignet med forbindelsen i eks. 1 i den ovennevnte patentsøknad, at de lettere kan oppnås ved at de ikke krever et endelig N-alkyleringstrinn som gir problemer i forbindelse med rensing ved fremstilling i industriell måle-stokk . Furthermore, the compounds according to the present invention have the advantage compared to the compound in ex. 1 in the above-mentioned patent application, that they can be obtained more easily in that they do not require a final N-alkylation step which causes problems in connection with purification during production on an industrial scale.

Blandingen omrøres i 12 timer ved romtemperatur. Trietylaminhydrokloridet fjernes ved filtrering. Preparation of 5-[3-hydroxy-2-(hydroxymethyl)-propionamido-1-N,N'-dimethyl-N,N'-bis-(2,3-dihydroxypropyl)-2,4,6-triodisophthalamide. a) Preparation of [2-isopropyl-1,3-dioxane-5-carboxamido]-N,N'-dimethyl-N,N'-bis-(2,3-dihydroxypropyl)-2,4,6-triiodoiso- phthalamide. 74 g (98 mmol) of 5-[2-isopropyl-1,3-dioxane-5-carboxamido]-2,4,6-triiododisophthaloyl dichloride are suspended in 300 ml of isopropanol containing 41 ml (294 mmol) of triethylamine. 31 g (295 mmol) of N-methyl-aminopropane-2,3-diol are added dropwise. The mixture is stirred for 12 hours at room temperature. The triethylamine hydrochloride is removed by filtration.
Filtratet avdampes til tørrhet, og resten tas opp i vann og elueres fra 0H- harpiks IRA 67. The filtrate is evaporated to dryness, and the residue is taken up in water and eluted from OH resin IRA 67.
Etter avdamping renses produktet ved at det føres gjennom silanisert silika (Kieselgel 60 Merck) med vann som elueringsmiddel. After evaporation, the product is purified by passing it through silanized silica (Kieselgel 60 Merck) with water as eluent.
Etter ^avdamping til tørrhet oppnås 60 g av et hvitt pulver i et utbytte på 68,5 %. After evaporation to dryness, 60 g of a white powder are obtained in a yield of 68.5%.
