THE INVENTION CONCERNS NEW PTERINE DERIVATIVES AND THEIR USE IN THE RADIOIMMUNOLOGICAL DETERMINATION OF PTERINS. THE COMPOUNDS OF THE INVENTION RESPOND TO THE GENERAL FORMULA: (CF DRAWING IN BOPI) IN WHICH R REPRESENTS A HYDROXYPHENYL, HYDROXYPHENYL RADIO-IODINE, TYRAMINOCARBONYL, TYRAMINOCARBONYL RADIO-IODINE, PROTEIN ORINOCARBONYL GROUP; Q REPRESENTS A STRAIGHT OR BRANCHED C-C ALKYLENE GROUP; AND R AND R EACH REPRESENT A HYDROGEN ATOM OR A C-C ALKYL, OR C-C HYDROXYALKYL. APPLICATION: THE COMPOUNDS IN WHICH R IS A RADIO-IODINE HYDROXYPHENYL OR RADIO-IODINE TYRAMINOCARBONYL GROUP ARE USED AS TRACERS IN THE RADIO-IMMUNOLOGICAL DETERMINATION OF PTERINS. |
