Abstract:
The present invention relates particularly to novel preorganized hexadentate ligands that are suitable for complexing with a radionuclide, and are useful as general imaging agents for diagnostic purposes. They have general formula (I), wherein R1 and R3 are the same or different and are selected from the group consisting of hydrogen, alkyl, aryl hydroxyl, alkoxyl, mono- or poly- hydroxyalkyl, mono- or poly- alkoxyalkyl, alkoxycarbonyl or carbamoyl; l and m may be the same or different and are from 2 to 5; Q and Z may be the same or different and are an O, N or S atom; and X and Y may be the same or different and are selected from the group consisting of (a), wherein R4-R6 may be the same or different and are selected from the group consisting of hydrogen, alkyl, aryl, hydroxyl, alkoxyl, mono- or poly- hydroxyalkyl, mono- or poly- alkoxy-alkyl, alkoxycarbonyl, amino, alkylamino, aminoalkyl, or carbamoyl.
Abstract:
A 2-amino-1,3-propanediol compound represented by general formula (I) or a pharmaceutically acceptable salt thereof, and an immunosuppressant containing the same as the active ingredient. In said formula R represents optionally substituted linear or branched carbon chain, optionally substituted aryl or optionally substituted cycloalkyl; and R?2, R3, R4 and R5¿, which may be the same or different from one another, represent each hydrogen, alkyl, aralkyl, acyl or alkoxycarbonyl. The compound is immunodepressant and useful as an inhibitor against rejection in organ or bone marrow transplantation, as a preventive or remedy for autoimmune diseases and so forth, or a reagent in the medical and pharmaceutical fields.
