Research Abstract |
We aimed at the development of the imaging probe for early diagnosis of Alzheimer's disease (AD). The cognitive impairment of AD is related to the cholinergic nerve system. we targeted the cholin transporter(ChT) and the acetylcholine transporter(VAChT) which exist in pre-synapse in cholinergic nerve. We synthesized the imaging probes with high affinity for ChT or VAChT. We could not develope a probe with high affinity for ChT in in vitro assays. However, I could synthesize a probe with high affinity for VAChT such as (-)-o-iododecalinvesamicol(OIDV). Radioiodinated OIDV ((-)-[I-125]OIDV) accumulated in rat brain through B.B.B. In vivo blocking and ex vivo autoradiography study showed that (-)-[I-125]OIDV selevtively accumulated in the VAChT in rat brain. These results showed that (-)-[I-125]OIDV bound selectively to VAChT in rat brain in vivo. Radioiodinated (-)-OIDV labeled with I-123 was suggested to be useful as a VAChT imaging agent for SPECT.
