Abstract

To continue our efforts toward the development of 99mTc PiB analogs, we have synthesized 24 neutral and lipophilic Re (as a surrogate of 99mTc) 2-arylbenzothiazoles, and explored their structure–activity relationship for binding to Aβ1–40 fibrils. These Re complexes were designed and synthesized via the integrated approach, so their 99mTc analogs would have a greater chance of crossing the blood–brain barrier. While the lipophilicities (logPC18= ...
