Abstract: To reduce the molecular weight of 99mTc-labelled tropanes with the aim to enhance the passage over the blood-brain barrier, a so-called integrated tropane-BAT construct was developed. For this purpose a mercaptoethyl substituent was attached to the amine nitrogen atom of a nortropane precursor and the methyl carboxylate in 2beta-position was converted to a 2-mercaptoethylaminomethylene substituent. This integrated tropane-BAT construct could be labelled efficiently (85-90%) with technetium-99m. Results of LC-MS analysis of the tracer agent support the assumed structure. Biodistribution studies in normal rats (n=3) showed a slightly higher brain uptake for the new tracer agents as compared to 99mTc-TRODAT-1. These results indicate that further biological evaluation of the integrated 99mTc-tropane-BAT is warranted.
