A precursor SnBZM for a dopamine receptor radiotracer and a method for preparing the same are revealed. The precursor includes a tributyltin group (Bu
3
Sn) that is easy to be replaced. Thus a dopamine receptor radiotracer
123
I-IBZM can be produced at high yield rate by a substitution reaction of the precursor. At the same time, both the method for preparing the precursor SnBZM and a method for preparing a reference standard IBZM are simplified. Moreover, stability of each product is improved.
揭示了一种用于
多巴胺受体放射示踪剂的前体SnB
ZM以及制备该前体的方法。该前体包括一个易于被替换的三
丁基锡基团(Bu3Sn)。因此,通过对前体的取代反应,可以高产率地生产
多巴胺受体放射示踪剂123I-IB
ZM。同时,简化了制备前体SnB
ZM和制备参比标准IB
ZM的方法。此外,提高了每个产品的稳定性。
