Compositions and methods for chemical exchange saturation transfer (CEST) based magnetic resonance imaging (MRI) or frequency labeled exchange (FLEX) imaging are disclosed. Beta-hydroxycarboxylate and beta-aminocarboxylate derivatives including salicylic acid, salicylates, salicylic acid prodrugs, N-alkyl/aryl/acyl/sulfonyl-anthranilic acid analogs, and any aromatic compound with OH/NH group ortho to the carboxylic acid group are disclosed. Such compounds can be used as general MRI organic contrast agents and produce significantly improved contrast in MR images detectable through CEST or FLEX.
本研究公开了基于化学交换饱和转移(CEST)的磁共振成像(MRI)或频率标记交换(FLEX)成像的组合物和方法。本发明公开了β-羟基羧酸盐和β-氨基羧酸盐衍生物,包括水杨酸、水杨酸盐、水杨酸原药、N-烷基/芳基/酰基/磺酰基-蒽酸类似物,以及羧酸基团正交有 OH/NH 基团的任何芳香族化合物。这些化合物可用作一般的核磁共振成像有机对比剂,并能显著改善通过 CEST 或 FLEX 检测到的核磁共振成像对比度。
