The present invention relates to bifunctional compounds, the bifunctional compounds for use in molecular imaging and therapy, methods of molecular imaging using the bifunctional compounds and kits including the bifunctional compounds for use molecular imaging. The bifunctional compounds have a tripodal hydroxypyridinone chelating portion and may be conjugated to a targeting group so that the compounds target specific cells or tissues in a subject.

four-directional core to produce the first-generation dendrimers (e.g., 9−11). The related second-generation dendrimer (15), possessing two different functional groups on both the surface and interior, was convergently synthesized from monomer 3. Alternatively, the mixed ester 17 was prepared starting with benzyl 4-nitrobutanoate (16); selective deprotection offered access to the representative 1 → (2 + 1)
为了提供通往多官能化树枝状聚合物的途径,设计并合成了具有酯和被保护的羟基或混合酯的新型1→(2 + 1)C-支链单体。因此,二-叔丁基4-(3- [X]氧丙基)-4- aminoheptanedioate(X =梅科,4 ; X = CH 2 CH 2 CN,6 ; X = CH 2 C ^ 6 ħ 5,7)是通过保护硝基前体2(X = H)制备高收率的化合物,这很容易从4-硝基丁醇与叔胺的迈克尔加成反应中获得丙烯酸丁酯,然后催化还原。这些单体容易附加到合适的四方向核心以产生第一代树枝状聚合物(例如,9 - 11)。从单体3聚合合成了相关的第二代树枝状聚合物(15),在表面和内部均具有两个不同的官能团。或者,以4-硝基丁酸苄酯(16)为起始原料制备混合酯17;和 选择性脱保护提供了对代表性的1→(2 +1)C支链单体20的访问,该单体已转化为树状聚合物29和30每个树突具有一个新的末端。这些1→(2
