Compounds that include a targeting moiety bound to a regioselective leaving group are useful for preparing imaging agents. The imaging agents can be isolated from byproducts derived from the leaving group based on differences in the chemical attributes (e.g., net charge or polarity) of the molecules or physical attributes of the molecules through the use of a solid support. Methods of producing an imaging agent include the steps of providing a compound that includes a targeting moiety bound to a support via a linker group that contains a site for regioselective substitution of a detectable species, contacting the compound with a solution containing the detectable species, and recovering the imaging agent. Kits which include a first container (5) having therein a solution (31) containing a detectable species and a second container (2) having therein a compound that includes a targeting moiety bound to a support (30) via a leaving group that contains a site for regioselective substitution of the detectable species are also useful for preparing imaging agents.
将包括与一个区域选择性离去基团结合的靶向基团的化合物用于制备成像剂是有用的。这些成像剂可以通过固体支持物来分离出来,基于分子的化学属性(例如净电荷或极性)或物理属性之间的差异,以此与离去基团衍生的副产物进行区分。制备成像剂的方法包括以下步骤:提供一个包含通过链连接基团与支持物相结合的靶向基团的化合物,该链连接基团包含一个用于区域选择性取代可检测物种的位点;将该化合物与含有可检测物种的溶液接触;并回收成像剂。还有一种用于制备成像剂的工具包,其中包括一个第一容器(5),其中含有一个含有可检测物种的溶液(31),以及一个第二容器(2),其中含有一个通过含有一个用于区域选择性取代可检测物种的离去基团的位点而与支持物(30)相结合的靶向基团的化合物。
